+## 1.0.2 - 2016-02-24
+
+This release fixes issues related to installing the component without
+any dev dependencies or with packages that don't have a source or dist
+reference, which is usual with packages defined directly in the
+`composer.json`.
+
+Total issues resolved: **3**
+
+- [11: fix composer install --no-dev PHP7](https://github.com/Ocramius/PackageVersions/pull/11)
+- [12: Packages don't always have a source/reference](https://github.com/Ocramius/PackageVersions/issues/12)
+- [13: Fix #12 - support dist and missing package version references](https://github.com/Ocramius/PackageVersions/pull/13)
+
+## 1.0.1 - 2016-02-01
+
+This release fixes an issue related with composer updates to
+already installed versions.
+Using `composer require` within a package that already used
+`ocramius/package-versions` caused the installation to be unable
+to write the `PackageVersions\Versions` class to a file.
+
+Total issues resolved: **6**
+
+- [2: remove unused use statement](https://github.com/Ocramius/PackageVersions/pull/2)
+- [3: Remove useless files from dist package](https://github.com/Ocramius/PackageVersions/pull/3)
+- [5: failed to open stream: phar error: write operations disabled by the php.ini setting phar.readonly](https://github.com/Ocramius/PackageVersions/issues/5)
+- [6: Fix/#5 use composer vendor dir](https://github.com/Ocramius/PackageVersions/pull/6)
+- [7: Hotfix - #5 generate package versions also when in phar context](https://github.com/Ocramius/PackageVersions/pull/7)
+- [8: Versions class should be ignored by VCS, as it is an install-time artifact](https://github.com/Ocramius/PackageVersions/pull/8)
