### Removed
- Pxo files saved with versions prior to v0.8 can no longer get loaded starting version 0.11.2. If you have old files that you need to load, load them in an earlier version first (from v0.8 to v0.11.1) and save them again. [#904](https://github.com/Orama-Interactive/Pixelorama/pull/904)
- Implemented a "smart slicer" system that lets the software automatically slice a spritesheet in separate frames on image import, without the user having to specify horizontal and vertical frames. [#893](https://github.com/Orama-Interactive/Pixelorama/pull/893)
- Added optional integer zooming for the canvas, which can be enabled from the Preferences. Disabled by default. [#894](https://github.com/Orama-Interactive/Pixelorama/pull/894)

- Fixed image effect animations appearing when changing the affected option, even if that image effect had no animatable properties. [#879](https://github.com/Orama-Interactive/Pixelorama/pull/879)
- 3D layers have now been implemented, which allows for non-destructive usage of 3D geometry inside Pixelorama. The 3D objects get automatically rasterized (pixelated) depending on the size of the canvas. [#840](https://github.com/Orama-Interactive/Pixelorama/pull/840)
- A perspective editor has been added, that aims to help artists use perspective in their work. [#806](https://github.com/Orama-Interactive/Pixelorama/pull/806)
- Dynamics are finally here! You can now use tablet pen pressure and/or mouse/pen velocity to affect the size and the alpha of the brush. More options will come in the future!
- A new crop tool has been added. It can resize the canvas without resizing the content. [#830](https://github.com/Orama-Interactive/Pixelorama/pull/830)
- Exporting and loading APNG files is now possible. [#772](https://github.com/Orama-Interactive/Pixelorama/pull/772) and [#797](https://github.com/Orama-Interactive/Pixelorama/pull/797)

- Your art progress inside Pixelorama can now be recorded and saved as screenshots, for you to combine into a video. Useful for art timelapses. [#823](https://github.com/Orama-Interactive/Pixelorama/pull/823)
- Control + Mouse wheel can now be used to adjust the brush size and shape thickness. Unfortunately, this shortcut cannot be edited at the moment, but it will be in the future (most likely once we port to Godot 4.x). [#776](https://github.com/Orama-Interactive/Pixelorama/discussions/776)
- Selections now have their own tile mode option, that works within the boundaries of the selection. [#834](https://github.com/Orama-Interactive/Pixelorama/pull/834)
- A way to easily preview an animation that has frames drawn in the form of a spritesheet/atlas has been added in the canvas preview. [#835](https://github.com/Orama-Interactive/Pixelorama/pull/835)
- The average color between the two selected colors is now shown in the color pickers, and can be easily picked. [#822](https://github.com/Orama-Interactive/Pixelorama/pull/822)
- A list of the recently used project sizes now appears on the new project dialog. [#819](https://github.com/Orama-Interactive/Pixelorama/pull/819)
- The palette panel is now more reactive; it automatically resizes in order to show/hide swatches based on its size. It is also now possible to scroll palettes with the mouse wheel, and resize the swatches with Control + mouse wheel. [#761](https://github.com/Orama-Interactive/Pixelorama/pull/761)
- Linked cels have been refactored, which allows for having multiple linked sets of cels in the same layer. [#764](https://github.com/Orama-Interactive/Pixelorama/pull/764)
- Gradient generation is now more powerful; there is now support for multi-color gradients and they can be repeated. Step gradients have been removed in favor of linear gradients with constant interpolation.
- The color picker now picks any visible color on the canvas, regardless of layer. A toggle has also been added in the tool options to let the user change back to the previous behavior of only picking a color on the selected layer. [#816](https://github.com/Orama-Interactive/Pixelorama/pull/816)
- A single popup appears when exporting multiple files that already exist, instead of showing one popup for each file to overwrite. [#585](https://github.com/Orama-Interactive/Pixelorama/discussions/585)

- Onion skinning settings are now being saved and are remembered between sessions. [#857](https://github.com/Orama-Interactive/Pixelorama/pull/857)
- The timeline has been refactored behind the scenes, and its performance has been massively improved for projects with a lot of frames and layers. [#698](https://github.com/Orama-Interactive/Pixelorama/pull/698)
- If Pixelorama crashes during saving of a .pxo file and a file of the same name already exists in that directory, it no longer gets replaced with an empty 0 byte file. [#763](https://github.com/Orama-Interactive/Pixelorama/issues/763)
- The movement preview now works as intended for all selected cels [#811](https://github.com/Orama-Interactive/Pixelorama/pull/811) for the move tool, [5cb0edd](https://github.com/Orama-Interactive/Pixelorama/commit/5cb0eddae5983b29a378a34ad4919116f911a403) for the selected content.
- Opening the rotate image dialog twice on large canvases no longer results in a crash. [ad61ddc](https://github.com/Orama-Interactive/Pixelorama/commit/ad61ddc2c0c251e8e20da3369c072e48380c0cd3)
- Pasted content should no longer get placed in sub-pixel positions. [403539b](https://github.com/Orama-Interactive/Pixelorama/commit/403539bb4794d81289214c4eda5226e70b9af19a)
- Drawing with image brushes no longer results in pixels outside the selection, if it exists. [30d279c](https://github.com/Orama-Interactive/Pixelorama/commit/30d279c4948b5712dac87bf6575932ca30d1c4dc)
- Using the selection gizmos when an overlay window is directly on top of them is no longer possible.
- Fix bug where the tool changes from a draw tool to a non-draw tool, while having an image brush selected. The bug was that the indicator was appearing as a white square, until the user moved their mouse.
- Fix bug where clicking on previous/next frame when only one frame exists makes the cel unselected. [6b58768](https://github.com/Orama-Interactive/Pixelorama/commit/6b587688f12dcc027c2f43832f179e4dca73a702)
- Fix selection handles and shape tool previews not working properly when mirror view is enabled. [#860](https://github.com/Orama-Interactive/Pixelorama/pull/860)
- The right tool gets activated only if the right mouse button (or whatever input action is assigned) is first pressed. [cc332c6](https://github.com/Orama-Interactive/Pixelorama/commit/cc332c6cbf3f9265a95a4bdc4998c9ca6c4f750a)
- No more errors in the debugger or the terminal appear when attempting to undo/redo while drawing. [af2b1fe](https://github.com/Orama-Interactive/Pixelorama/commit/af2b1feb1f63144ebce00520ea2f8ee832dc49bd)
- The UI now automatically gets scaled, based on the dpi and resolution of the monitor. Resolves [#643](https://github.com/Orama-Interactive/Pixelorama/issues/643).
- A "Divide into equal parts" button has been added in Gradient Map. This is meant for easy gradient bisecting, which is helpful for converting Linear/Cubic interpolated gradients into Constant. This will eventually be used in gradient generation as well, once multi-color gradient generation support gets implemented.
- A new fill area option has been added to the bucket tool options, "Whole Selection". This fills the entire selection with a color or pattern, regardless of the colors of the pixels.
- Palette swatches now get highlighted if their color is selected from the color buttons. [#730](https://github.com/Orama-Interactive/Pixelorama/pull/730)
- Copy, cut & delete now affect the entire cel if there is no selection.
- The paste placement behavior has been changed. Paste now places the pasted content in the middle of the canvas view, instead of its original position. A new option in the Edit menu has been added, "Paste in Place", that preserves the previous behavior.
- The left & right tool options now have a header with the name of the currently selected tool, and a color indicator on the top.
- The preferences dialog has been polished. Headers have been added for each segment, and all of the elements are now vertically aligned with each other.
- The recent projects menu now makes the most recent project appear on top, and if you open a project already in the recent projects list, it would then be moved to the most recent spot on the list. [#755](https://github.com/Orama-Interactive/Pixelorama/pull/755)
- The import dialog now remembers the last option. [#754](https://github.com/Orama-Interactive/Pixelorama/pull/754)
- Fix invalid pattern image error when using the bucket tool to replace colors.
- Fixed issue with the bucket tool where if the selected color is the same as the pixel's color in mouse position, the operation stops even if there are other cels selected.
- The "Close" button in the preferences no longer remains stuck in the previous language, if the language changes and the previous one was not English.
- Copying now works between multiple Pixelorama instances, and the clipboard is even being remembered when the app closes. Note that you cannot copy image data to another software, and you cannot paste image data from another software into Pixelorama. [#693](https://github.com/Orama-Interactive/Pixelorama/pull/693)
- Importing multiple images at once from File, Open is now possible.
- On image effect dialogs, the preview will show all of the selected cels instead of only one cel. [#722](https://github.com/Orama-Interactive/Pixelorama/pull/722)
- The icon for onion skinning options has changed. [#711](https://github.com/Orama-Interactive/Pixelorama/pull/711)

- Even-numbered thickness sizes on the rectangle and ellipse shape tools now work as expected. The thickness of the shapes no longer goes up by 2 pixels. [23f591a](https://github.com/Orama-Interactive/Pixelorama/commit/23f591a8626c12fd7e6344ab59f8e33b8d20cb99)
- [[Keychain](https://github.com/Orama-Interactive/Keychain)] Fixed issue with menu events being triggered by actions that are not exact matches. This means that, for example, "Control + Shift + S" will no longer activate both "Save" and "Save as", but only "Save as". [09c9583](https://github.com/Orama-Interactive/Keychain/commit/09c95835ef034effa949732cf9cf9bd315ed08a8)
- Massively improved the performance of the selection system, most notably the Rectangle Selection and Select by Color tools, and selection content deletion. [#710](https://github.com/Orama-Interactive/Pixelorama/pull/710)
- Performance when drawing big lines on big canvases has been increased, thanks to the update to Godot 3.5. Most likely due to [godotengine/godot#62826](https://github.com/godotengine/godot/pull/62826)
- Fixed issue with save file dialog taking the name of the first file it sees. [5d65e82](https://github.com/Orama-Interactive/Pixelorama/commit/5d65e820708ed7586fdb7f0ac4633f7b468ec73d)
- Fixed grid-based snapped movement when the offset of the grid was larger than the grid size. [#712](https://github.com/Orama-Interactive/Pixelorama/pull/712)

- The [Keychain plugin](https://github.com/Orama-Interactive/Keychain) has been implemented. Keychain makes Pixelorama's shortcut system fully configurable, and it provides the ability to the users to set custom shortcuts of every input type for all input actions. The plugin is developed by us and it's free to use for your own Godot projects as well! [#700](https://github.com/Orama-Interactive/Pixelorama/pull/700)
- The cursor can now be moved with the numpad arrow keys and gamepad's left stick and d-pad, the canvas can be moved with gamepad's right stick and it is also possible to map the activate left and right tool actions to keyboard and gamepad buttons, to allow drawing from these devices, making Pixelorama a lot more accessible. Made possible by the Keychain plugin.
- A lot more gradient options have been added. Apart from the Linear Step gradient, there are now Linear, Radial, Radial Step, Linear Dithering and Radial Dithering gradient types. They are all shader-based, so they are a lot faster than the previous method. [#677](https://github.com/Orama-Interactive/Pixelorama/pull/677)
- A drop shadow image effect has been added. [#674](https://github.com/Orama-Interactive/Pixelorama/pull/674)
- A new rotation method has been added. It is shader-based, therefore faster than the other methods. [#683](https://github.com/Orama-Interactive/Pixelorama/pull/683)
- The export window is now more clear if the directory path, the file name or both are invalid. [#669](https://github.com/Orama-Interactive/Pixelorama/pull/669)
- Timeline scroll behavior has been tweaked. [#682](https://github.com/Orama-Interactive/Pixelorama/pull/682)

- It is now possible to delete content from all selected cels.
- The flood fill algorithm (bucket tool's "same color area" mode) is now a lot faster. [#667](https://github.com/Orama-Interactive/Pixelorama/pull/667) and [#672](https://github.com/Orama-Interactive/Pixelorama/pull/672)
- Going into fullscreen mode and then exiting it no longer makes the window opacity not working properly. Note that window opacity still does not work when in fullscreen mode.
- A new Window menu has been added that has the new UI system options, as well as Zen mode and Fullscreen mode that were previously under the View menu.
- A similarity option has been added to the "same color pixels" mode of the bucket tool. [#649](https://github.com/Orama-Interactive/Pixelorama/pull/649)
- Added an experimental Extensions system that will let the users make their own extensions that add new functionality to Pixelorama. Keep in mind that this is still experimental and backwards compatibility is NOT guaranteed - use at your own risk.
- A grayscale mode for the canvas has been added to the View menu. [#646](https://github.com/Orama-Interactive/Pixelorama/pull/646)
- Bulk importing images has been made easier by adding an "Apply to all" checkbox that uses the same import options for all images that are to be imported. [#624](https://github.com/Orama-Interactive/Pixelorama/pull/624)
- Extra cursor options have been added to the Preferences that let the user use the native mouse cursors of the OS and toggle the cross cursor on or off for the canvas, and the "Indicators" tab has been renamed to "Cursors".
- Frame duration now appears as a hint tooltip of the frame buttons.
- Added Portuguese translation.
### Changed
- The UI system has changed completely. Users can re-arrange all of the panels and place them wherever they want, resize them or hide them from view. It is also possible to save and load custom UI layouts. [#640](https://github.com/Orama-Interactive/Pixelorama/pull/640)
- The secondary canvas is hidden from view by default, but it can become visible by going to the Window > Panels.
- The mirroring and pixel perfect options are now global tool options and affect both left and right tools.
- Various timeline improvements, like deleting and cloning multiple selected frames and when creating new frames, tags that are in front of them are being pushed. If the currently selected frames are inside a tag, creating new frames makes the tag bigger. [#648](https://github.com/Orama-Interactive/Pixelorama/pull/648)
- The custom mouse cursor now scales with the UI. [#642](https://github.com/Orama-Interactive/Pixelorama/issues/642)
- Importing an image will replace the previous project, if that project is empty.
- Clicking on a layer toggle button (lock, visible & cel linking) now selects that layer.
- Resize Canvas will always display the current size of the project.
- Imported images can now be immediately exported, and for imported png images "Overwrite" is being displayed instead of "Export", until the user uses "Export as...".
- Drawing with big brush sizes has been optimized. [#657](https://github.com/Orama-Interactive/Pixelorama/pull/657) - which was based on [#554](https://github.com/Orama-Interactive/Pixelorama/pull/554)
- The "same color pixels" mode of the bucket tool has become a lot faster because it now uses a shader. [#649](https://github.com/Orama-Interactive/Pixelorama/pull/649) - which was based on [#613](https://github.com/Orama-Interactive/Pixelorama/pull/613)
- Fixed crash when importing non-palette .tres files.
- Deferred mode for the color pickers of gradients has been enabled, so that the gradient preview color only changes on mouse release. Addressed a part of [#645](https://github.com/Orama-Interactive/Pixelorama/issues/645).
- "From Current Palette" preset option is now disabled when creating a new palette, if there is no current palette, which fixes [#659](https://github.com/Orama-Interactive/Pixelorama/issues/659)
- Aspect ratio in scale image no longer sets width and height to have the same value, but it works as expected like it does in the create new image dialog.
- Added an option in the preferences that toggles confirmation while quitting. This has no effect if there are unsaved changes in any of the projects, the confirmation will always appear in that case.
- Massively improved memory management by fixing a memory leak. Previously, every time the user made a change, memory kept going up and never coming down. Now, data that can never be recovered, like undo data that have been rewritten in history, are also removed from memory. [4832690](https://github.com/Orama-Interactive/Pixelorama/commit/48326900d9d9f0b32fd435e56fd5a39bbf13fa36)

- Fixed issues with guides and notifications not working properly when the UI is scaled.
- A bug was fixed where when the user has another application as their focus and reenters Pixelorama with the mouse but not focusing it and then exiting with the mouse, the target FPS would be set to the standard. [#543](https://github.com/Orama-Interactive/Pixelorama/pull/543)
- An installer for Windows will be available for v0.9 and future versions! [#486](https://github.com/Orama-Interactive/Pixelorama/pull/486)
- You can now select multiple cels in the timeline and edit them all at once!

- You can now right click a cel to delete its contents.
- Layer dragging and dropping is now also possible.
- A new "fill inside" option has been added in the Pencil tool options. [#489](https://github.com/Orama-Interactive/Pixelorama/pull/489), based off [#459](https://github.com/Orama-Interactive/Pixelorama/pull/459)
- The selection system has been completely changed and has become a lot more powerful. See [#129](https://github.com/Orama-Interactive/Pixelorama/issues/129#issuecomment-756799706) for more details.
- The palette system has been completely replaced with a new one. See [#447](https://github.com/Orama-Interactive/Pixelorama/pull/447) for more details.
- UI icons have been changed to single-color "symbolic" textures. This removes the need for multiple graphics for each theme type as these new textures can change their modulation on runtime.
- Image color inverting, desaturation and HSV adjusting are now shader based. This improves the performance of these image effects and prevents crashes on large images. [#475](https://github.com/Orama-Interactive/Pixelorama/pull/475)
- The color picker tool now works on the surrounding tiles when tile mode is enabled. [#506](https://github.com/Orama-Interactive/Pixelorama/issues/506)
- Issues such as not being able to create guides at random times, which are a result of PoolVectorArray locking issues, may have finally been solved. [#331](https://github.com/Orama-Interactive/Pixelorama/issues/331)
- Cropping large images no longer crash the application.
- Zen mode now hides the animation timeline again. [#478](https://github.com/Orama-Interactive/Pixelorama/pull/478)
- Pixelorama should no longer crash when loading a project and the symmetry axes fail to load. They will still fail to load, but the app will no longer crash. [e8b36bbc61154641ce9eec1f0a845a0061d3585d](https://github.com/Orama-Interactive/Pixelorama/commit/e8b36bbc61154641ce9eec1f0a845a0061d3585d)
- The shading tool now has correct Hue, Saturation and Value changes, as well as some other tweaks, like limiting the darkening hue to 240 instead of 270. [#519](https://github.com/Orama-Interactive/Pixelorama/pull/519) and [#522](https://github.com/Orama-Interactive/Pixelorama/pull/522)
- You can now change the transparency of the application's window, allowing for easier tracing/rotoscoping. (Does not work on the Web version) ([#444](https://github.com/Orama-Interactive/Pixelorama/pull/444))
- Added a new pixel grid, which is a grid of size 1px and it appears after a certain zoom level. ([#427](https://github.com/Orama-Interactive/Pixelorama/pull/427))
- The isometric grid has been refactored to work better and to offer more changeable options, such as the width and height of the cell bounds. ([#430](https://github.com/Orama-Interactive/Pixelorama/pull/430))
- Added a new Centralize Image option in the Image menu, which places the visible pixels of the image in the center of the canvas. ([#441](https://github.com/Orama-Interactive/Pixelorama/pull/441))
- Implemented the options to import a spritesheet as a new layer and to import an image and have it replace an already existing frame. ([#453](https://github.com/Orama-Interactive/Pixelorama/pull/453))
- More templates have been added when creating a new sprite. ([#450](https://github.com/Orama-Interactive/Pixelorama/pull/450))
- Added a keyboard shortcut for clear selection, `Control-D`. ([#457](https://github.com/Orama-Interactive/Pixelorama/pull/457))
- Added an option in the Preferences for interface dimming on dialog popup. If this is enabled, the application background gets darker when a dialog window pops up.
- You can now toggle if you want the grid to be drawn over the tile mode or just the original part of the canvas. ([#434](https://github.com/Orama-Interactive/Pixelorama/pull/434))
- Frame tags can now be set for frames larger than 100. ([#408](https://github.com/Orama-Interactive/Pixelorama/pull/408))
- Improved the "Scale Image" dialog. It now automatically sets the size to the current project's size, has a button to lock aspect ratio, and resizing based on percentage.
- Having no active selection no longer treats all the pixels of the canvas as selected. This is also a performance boost, especially for larger images, as Pixelorama no longer has to loop through all of the pixels to select them.
- Fixed issue with pixels being selected outside of the canvas boundaries, when the selection rectangle was outside the canvas and its size got reduced.
- Fixed layer button textures not being updated properly when changing theme. ([#404](https://github.com/Orama-Interactive/Pixelorama/issues/404))
- Keyboard shortcut conflicts between tool shortcuts and other shortcuts that use the "Control" key, like menu shortcuts, have been resolved. ([#407](https://github.com/Orama-Interactive/Pixelorama/pull/407))
- The opacity of a cel and the tile mode opacity are now multiplicative. ([#414](https://github.com/Orama-Interactive/Pixelorama/pull/414))
- Fixed an issue where adding a new layer did not select it, rather it was selecting the above layer of the previously selected layer. ([#424](https://github.com/Orama-Interactive/Pixelorama/pull/424))
- Fixed issue that occurred when the application window regained focus and the tool was immediately activated. ([35f97eb](https://github.com/Orama-Interactive/Pixelorama/commit/35f97ebe6f90bd2a5994b294231738ef4a6b998c))
- The lighten/darken tool now has a hue shifting mode. It lets users configure the shift in hue, saturation and value of the new shaded pixels. ([#189](https://github.com/Orama-Interactive/Pixelorama/issues/189))
- Added a "frame properties" option on the popup menu that appears when right-clicking on a cel. This lets the user choose a custom frame delay for that specific frame. ([#357](https://github.com/Orama-Interactive/Pixelorama/pull/357))
- Added a "Recent Projects" option in the File menu, to contain the most recently opened projects. ([#370](https://github.com/Orama-Interactive/Pixelorama/pull/370))
- More options have been added to Tile mode; Tile only in X Axis, Y Axis or both Axis. ([#378](https://github.com/Orama-Interactive/Pixelorama/pull/378))
- Added a "Mirror View" option in the View menu, which is used to flip the canvas horizontally and non-destructively. ([#227](https://github.com/Orama-Interactive/Pixelorama/issues/227))
- The CJK font (for Chinese & Korean) was changed to DroidSansFallback from NotoSansCJKtc. This results in a much smaller exported `.pck` (over 10MB less!)
- Onion skinned previous and next frames are now being drawn on top of the current frame. This fixes issues where onion skinning would not work with an opaque background.
- macOS: Shortcuts with the Control keyboard button have now been changed to use "Command" instead. ([#393](https://github.com/Orama-Interactive/Pixelorama/pull/393))
- Fixed issue where the user could grab and could not let go of the focus of guides even when they were invisible.
- Fixed issues where fully transparent color could not be picked. One of these cases was [#364](https://github.com/Orama-Interactive/Pixelorama/issues/364).
- Fixed "Export" option in the File menu not working properly and not remembering the directory path and file name when switching between projects (tabs).
- Fixed freeze when switching to a project of a larger size and using an image effect, with the affected parts being set to something different that "Current cel".
- Creating palettes from sprites has been enhanced - you can now choose if you want to get colors from the selection, current cel, entire frame or all frames, and if you want the colors to have an alpha component.
- A new "Cut" option in the Edit menu or by pressing `Ctrl-X`. It cuts (deletes & copies) the selection, and you can later paste it. ([#345](https://github.com/Orama-Interactive/Pixelorama/pull/345))
- Most likely fixed an issue that occurred when the user attempted to export the project, which failed due to a locking error (error code 23). (Part of [#331](https://github.com/Orama-Interactive/Pixelorama/issues/3391))
- Fixed crash where Pixelorama could not load a cached sub-resource. ([#339](https://github.com/Orama-Interactive/Pixelorama/issues/339))
- Fixed issue with the selection rectangle, where if it was being moved while using paste or delete, it went back to its original position. ([#346](https://github.com/Orama-Interactive/Pixelorama/pull/346))

- The Web (HTML5) is now a supported platform of Pixelorama! It is now possible to save .png and .pxo files, as well as load image and palette files in the Web version. Made possible thanks to https://github.com/Pukkah/HTML5-File-Exchange-for-Godot
- Gradient generation. A new option under the "Image" menu that lets you generate a RGB gradient.
- The dialog windows of most image effects have been improved. You can now select if you want the effect to apply in the selection, the current cel, the entire frame, all frames or even all projects (tabs)!
- Added previews in all image effect dialog windows with a checkerboard background. Also placed checkerboard backgrounds in the cel buttons of the timeline, and the Export window. ([#206](https://github.com/Orama-Interactive/Pixelorama/issues/206))
- You can now drag & drop files into the program while it's running to open them. You can open .pxo files, image files and palette (json, gpl and pal) files this way.
- Selection region and size are now being shown when making a selection on the top, next to the position label. ([#281](https://github.com/Orama-Interactive/Pixelorama/pull/281))
- Flip, desaturation and invert colors now have dialogs with previews and extra options. You can now choose individual color channels to invert, including alpha.
- A play button has been added for playing the animation exclusively on the small canvas preview area. A zoom slider for the preview area has been added, too.
- Added color previews next to the themes in Preferences.
- Added options for the checkerboard background to follow camera movement and zoom level. ([#311](https://github.com/Orama-Interactive/Pixelorama/pull/311))
- The GDNative gif exporter addon has been replaced with a GDScript equivalent. This makes gif exporting possible in all currently supported platforms, and it also adds support for transparency. ([#295](https://github.com/Orama-Interactive/Pixelorama/pull/295))
- Drawing is no longer limited by the canvas boundaries. This means that, if you have a brush largen than 1px, you can draw on the edges of the canvas. All pixels that are being drawn outside of the canvas will still have no effect.
- Imported frames are now being cropped to the project's size. It is no longer possible to have multiple sizes for each frame at all in the same project.
- The .pxo file structure has been changed. It's now consisted of a JSON-structured metadata part, where all the data that can be stored as text are, and a binary part, that contain all the actual image data for each cel and project brush.
- You can now choose if you want your .pxo to use ZSTD compression or not.
- To make a straight line, you now have to hold Shift while dragging (moving and pressing) your mouse. Releasing your mouse button makes the line. ([#281](https://github.com/Orama-Interactive/Pixelorama/pull/281))
- When making a straight line, a preview of how the line's pixels will look is now being shown. ([#260](https://github.com/Orama-Interactive/Pixelorama/pull/260))
- Drawing lines with Ctrl are now constrained at 1:1 and 1:2 ([#201](https://github.com/Orama-Interactive/Pixelorama/issues/201))
- Pixelorama now remembers the selected colors, tools and their options when it's closed and re-opened. ([#281](https://github.com/Orama-Interactive/Pixelorama/pull/281))
- The "pixelorama" folder, which contains data like Brushes, Patterns and Palettes has been renamed to "pixelorama_data" for all non-XDG directory paths.
- Mac builds will now have the execute permission by default, and they will be in `.dmg` form. ([#319](https://github.com/Orama-Interactive/Pixelorama/pull/319))
- When making a new palette or importing one and its name already exists, Pixelorama will add a number to its name. For example, "Palette_Name" would become "Palette_Name (2)", "Palette_Name (3)", etc.
- The "create new image" dialog now remembers the last created canvas size. The default image settings are being used only when Pixelorama first launches. ([#178](https://github.com/Orama-Interactive/Pixelorama/issues/178))
- Fixed failed imports of gpl palettes by adding support for the newer variant of gpl files. ([#250](https://github.com/Orama-Interactive/Pixelorama/pull/250))
- When a color is being selected from a palette, the outline of the color's button no longer disappears when drawing. ([#329](https://github.com/Orama-Interactive/Pixelorama/pull/329))
- An autosave feature that keeps backups of unsaved projects have been added. In the case of a software crash, the users can restore their work with this system.
- You can now move the canvas with the `Arrow keys`. `Shift + Arrows` make it move with medium speed, and `Ctrl + Shift + Arrows` makes it move with high speed.
- The texture of the transparent checker background is now no longer affected by the zoom value. The users can now also change the texture's colors and the size.
- Layer visibility is taken into account when exporting the drawing as a `.png` file. This means that invisible layers will not be included in the final `.png` file.
- Onion skinning settings have been moved to a popup window, and 2 new buttons were added. One that toggles onion skinning, and one that opens the settings window.
- Palettes/Brushes get loaded/saved in appropriate locations as specified by the XDG basedir standard, for easier usage of standard Linux/BSD packaging methods and for better per-user usability.
- Chinese characters not being rendered in notifications (the labels that appear when undoing/redoing) and at the splash screen for Platinum & Gold Sponsor Placeholder labels
- Fixed issue with Space triggering the event of the last pressed button. This caused unwanted behavior when using Space to move the canvas around. Resolved by changing the focus mode of the buttons to None.
- The color picker will now have a small white triangle on the top left of the color preview if at least one of its RGB values are above 1 in Raw mode. (Added automatically because of the Godot 3.2 update)
- You can now toggle the visibility of hidden items on and off in the file dialogs. (Added automatically because of the Godot 3.2 update)
- The language buttons in the preferences have their localized names in their hint tooltips. For example, if you hover over the "English" button while the language is Greek, the hint tooltip will be "Αγγλικά", which is the Greek word for English.
- The grid options are now being updated realtime when they're being changed from the preferences, and they are also being saved in the config cache file.
- Fixed a rare crash with straight lines. It was possible that the variable `is_making_line` could be true, even if the line itself has been freed from memory.
- Added a new splash screen window dialog that appears when Pixelorama loads. Patrons with the rank of Visionaries and above can participate in splash screen artwork contests for every version! Click here for more info: https://www.patreon.com/OramaInteractive
- Added random brushes! Every time you draw, expect to see something different! To create random brushes, place the images you want your brush to have in the same folder, and put the symbol "%" in front of their filename. Examples, "%icon1.png", "%grass_green.png"
- Enabled low processor usage and reduced the amount of times "update()" gets called on Canvas and the rulers, to improve CPU usage. (Thanks to Calinou & Martin1991zab)
- Fixed alpha in custom brushes, because their alpha was being blended along with its RGB values. (Issue #51)
