  (#114 by @thojou and @clue)

• Minor documentation improvements and simplify install instructions.
  (#98 and #99 by @clue)

• Use GitHub actions for continuous integration (CI).
  (#112 by @SimonFrings and #113 by @szepeviktor)

• Feature: Update all dependencies and improve forward compatibility with symfony/console v5 through legacy v2.5.
  (#87 by @clue)

• Feature: Significantly improve performance when adding phar contents.
  (#90 by @clue)

• Feature: Support cloning projects from git SSH URLs.
  (#96 by @clue)

• Feature: Ignore packages without autoload definition and missing vendor directory.
  (#94 by @clue)

• Feature: Write phar to temporary file to support any extension and overwriting.
  (#93 by @clue)

• Feature / Fix: Disable install subcommand on Windows.
  (#95 by @clue)

• Improve test suite by adding PHPUnit to require-dev and support legacy PHP 5.3 through PHP 7.2 and HHVM,
  add tests for all commands and perform some minor code cleanup/maintenance,
  minor internal refactoring to clean up some unneeded code duplication and unneeded references and
  remove dedicated bundler classes, always bundle complete package.
  (#85, #86, #89 and #92 by @clue)

• Add build script removing uneeded files and update development docs.
  (#91 by @clue)

• First stable release, now following SemVer.
• Feature: Can now be installed as a require-dev Composer dependency and
  supports running as ./vendor/bin/phar-composer.
  (#36 by @radford)
• Fix: Actually exclude vendor/ directory. This prevents processing all
  vendor files twice and reduces build time by 50%.
  (#38 by @radford)
• Fix: Fix error reporting when processing invalid project paths.
  (#56 by @staabm and @clue)
• Fix: Fix description of phar-composer install command.
  (#47 by @staabm)
• Updated documentation, tests and project structure.
  (#54, #57, #58 and #59 by @clue)

• Feature: The search command is the new default if you do not pass any command
  (#13).
  You can now use the following command to get started:

$ phar-composer

• Fix: Pass through STDERR output of child processes instead of aborting
  (#33)
• Fix: Do not timeout when child process takes longer than 60s.
  This also helps users with slower internet connections.
  (#31)
• Fix: Update broken dependencies
  (#18)
• Fix: Fixed an undocumented config key
  (#14, thanks @mikey179)

• Feature: New install command will now both build the given package and then
  install it into the system-wide bin directory /usr/local/bin (usually already
  in your $PATH). This works for any package name or URL just like with the
  build command, e.g.:

$ phar-composer install phpunit/phpunit

After some (lengthy) build output, you should now be able to run it by just issuing:

$ phpunit

• Feature: New search command provides an interactive command line search.
  It will ask for the package name and issue an search via packagist.org's API and
  present a list of matching packages. So if you don't know the exact package name,
  you can now use the following command:

$ phar-composer search boris

• Feature: Both build and install commands now also optionally accept an
  additional target directory to place the resulting phar into.

• Feature: Resulting phar files can now be executed on systems without
  ext-phar (#8). This vastly improves portability for legacy setups by including
  a small startup script which self-extracts the current archive into a temporary
  directory.
• Feature: Resulting phar files can now be executed without the phar file name
  extension. E.g. this convenient feature now allows you to move your ~demo.phar
  to /usr/bin/demo for easy system wide installations.
• Fix: Resolving absolute paths to vendor/autoload.php

• Feature: Packages can now also be cloned from any git URLs (#9), like this:

$ phar-composer build https://github.com/clue/phar-composer.git

The above will clone the repository and check out the default branch.
You can also specify either a tag or branch name very similar to how composer works:

$ phar-composer build https://github.com/clue/phar-composer.git:dev-master

• Feature: Packages listed on packagist.org can now automatically be downloaded and installed
  prior to generating phar (#7), like this:

$ phar-composer build clue/phar-composer

The above will download and install the latest stable tagged release (if any).
You can also specify a tagged version like this:

$ phar-composer build clue/phar-composer:0.1.*

Or you can specify to install the head of a given branch like this:

$ phar-composer build clue/phar-composer:dev-master

• Feature: Bundle complete project directories

• First tagged release
