- Added config.platform to let you specify what your target environment looks like and make sure you do not inadvertently install dependencies that would break it
- Added
exclude-from-classmap
in the autoload config that lets you ignore sub-paths of classmapped directories, or psr-0/4 directories when building optimized autoloaders - Added
path
repository type to install/symlink packages from local paths - Added possibility to reference script handlers from within other handlers using @script-name to reduce duplication
- Added
suggests
command to show what packages are suggested, use -v to see more details - Added
content-hash
inside the composer.lock to restrict the warnings about outdated lock file to some specific changes in the composer.json file - Added
archive-format
andarchive-dir
config options to specify default values for the archive command - Added --classmap-authoritative to
install
,update
,require
,remove
anddump-autoload
commands, forcing the optimized classmap to be authoritative - Added -A / --with-dependencies to the
validate
command to allow validating all your dependencies recursively - Added --strict to the
validate
command to treat any warning as an error that then returns a non-zero exit code - Added a dependency on composer/semver, which is the externalized lib for all the version constraints parsing and handling
- Added support for classmap autoloading to load plugin classes and script handlers
- Added
bin-compat
config option that if set tofull
will create .bat proxy for binaries even if Compoesr runs in a linux VM - Added SPDX 2.0 support, and externalized that in a composer/spdx-licenses lib
- Added warnings when the classmap autoloader finds duplicate classes
- Added --file to the
archive
command to choose the filename - Added Ctrl+C handling in create-project to cancel the operation cleanly
- Fixed version guessing to use ^ always, default to stable versions, and avoid versions that require a higher php version than you have
- Fixed the lock file switching back and forth between old and new URL when a package URL is changed and many people run updates
- Fixed partial updates updating things they shouldn't when the current vendor dir was out of date with the lock file
- Fixed PHAR file creation to be more reproducible and always generate the exact same phar file from a given source
- Fixed issue when checking out git branches or tags that are also the name of a file in the repo
- Many minor fixes and documentation additions and UX improvements
