### Credits

This is a major new release of Pinta, with large changes to its architecture
including porting to GTK4 and libadwaita. Using GTK4 also required porting Pinta
to use a new library (Gir.Core) for C# bindings to GTK and other GObject
libraries, so special thanks goes to @badcel and the @gircore contributors for
their excellent work on that project!

This release also coincides with a new and improved project website, contributed
by @rolandixor !

### Changed

- Due to API changes in GTK4, the File -> New Screenshot option now invokes
platform-specific tools (the XDG screenshot portal on Linux, and the screenshot
tool on maCOS). This is currently unsupported on Windows
- When building Pinta using the Makefile, 'dotnet publish' is now run during the build step rather than the install step.
- Added a "Reseed" button for the random noise used by several effects (such as "Add Noise" and "Frosted Glass"). Previously,
the noise pattern changed every time the effect was computed (including when other parameters were changed).
- Saving an image already saved in a format that supports multiple layers to a format that does not support layers will now
explicitly prompt the user to flatten the image before saving, rather than silently flattening it (#909)
- The add-in manager dialog now filters out old versions incompatible with the current version of Pinta, or new addins requiring
future version of Pinta (#1580205)
- The tool windows on the right side of the dock layout can now be completely hidden (#1179)
