  • Added COMPOSER_BIN_DIR env var and _composer_bin_dir global containing the path to the bin-dir for binaries. Packages relying on finding the bin dir with $BASH_SOURCES[0] will need to update their binaries (#10402)
  • Fixed issue when new binary proxies are combined with PHPUnit and process isolation (#10387)
  • Fixed deprecation warnings when using Symfony 5.4+ and requiring composer/composer itself (#10404)
  • Fixed UX of plugin warnings (#10381)
