TwelveMonkeys ImageIO 3.9.0

TwelveMonkeys ImageIO 3.9.0 release notes

The TwelveMonkeys ImageIO version 3.9.0 is ready for release.

Thanks to everyone who has committed code, patches, filed bug reports or otherwise contributed to the development of this version!

Special thanks to the following contributors:

• @Simon04090 for contributing the major parts of WebP lossless decoding
• @younseunghyun for PSD group layer support
• @Schmidor for several TIFF fixes and improvements
• @KoenDG for TGA bugfix, documentation and other improvements
• @astappiev for the Jakarta EE module generation
• @gotson for the new Github Actions build

What's new?

Improved WebP read support. We finally support WebP lossless, alpha and more of the animation (ANIM/ANMF) spec. All still images should now be correctly read.

Major overhaul of the metadata generation, for more correct and consistent metadata. Fixed a lot of minor issues in the "standard format" metadata.

Generally improved stream performance.

Support for the new Jakarta EE namespace in the servlet module. Now outputs a separate JAR for Jakarta EE, to allow usage in a Jakarta EE environment.
