2.0.10 - released 2021-02-23

Changelog

Added COMPOSER_MAX_PARALLEL_HTTP to let people set a lower amount of parallel requests if needed
Fixed autoloader registration when plugins are loaded, which may impact plugins relying on this bug (if you use symfony/flex make sure you upgrade it to 1.12.2+ to fix dump-env issues)
Fixed exec command suppressing output in some circumstances
Fixed Windows/cmd.exe support for script handlers defined as path/to/foo, which are now rewritten internally to path\to\foo when needed
Fixed bin handling on Windows for PHP scripts, to more closely match symlinks and allow @php vendor/bin/foo to work cross-platform
Fixed Git for Windows/Git Bash not being detected correctly as an interactive shell (regression since 2.0.7)
Fixed regression handling some private Bitbucket repository clones
Fixed Ctrl-C/SIGINT handling during downloads to correctly abort as soon as possible
Fixed runtime autoloader registration (for plugins and script handlers) to prefer the project dependencies over the bundled Composer ones
Fixed numeric default branches being aliased as 9999999-dev internally. This alias now only applies to default branches being non-numeric (e.g. dev-main)
Fixed support for older lib-sodium versions
Fixed various minor issues
