Full Changelog

• BC Break / Security: Disabled automatic fallback to source checkout if dist/zip install fails, we have introduced a new source-fallback config option as a temporary way to restore the old behavior, but if you need this talk to us as we plan to remove it entirely in 2.11 (#12885)

Full Changelog: composer/composer@2.9.8...2.10.0

2.10.0-RC2

Composer 2.10 is ready for a release, and we need your help to test it and report any regression.

Please try it out!

• Running composer self-update --preview will get you the 2.10.0-RC2
• Running composer self-update --stable will get you back on the latest 2.9 stable release if anything broke.
• Report any issues you encounter as a new issue specifying you tried the 2.10 RC and please include stack traces & repro details.

Full Changelog

• Since 2.10.0-RC1, fixes in 2.9.6 - 2.9.8, many of which security relevant, are also included
• Since 2.10.0-RC1 a lot of the new filter list config format was modified - see #12786 for the latest state of this new feature
• Added a new policy config block to control all security related update/install/audit policies. This replaces and deprecates most of the audit config (#12804 for implementation, #12786 for RFC/upgrade docs)
• Enabled blocking of malware packages at install time by default
• Fixed --no-plugins handling regression (#12789)
• Fixed regression in startup performance when many scripts are defined (#12832)
• Improved classmap dumping performance
