+25 November 2016
+----------------
+
+I've finally released gflags 2.2.0.
+
+This release adds support for use of the gflags library as external dependency
+not only in projects using CMake, but also [Bazel](https://bazel.build/),
+or [pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/).
+One new minor feature is added in this release: when a command flag argument
+contains dashes, these are implicitly converted to underscores.
+This is to allow those used to separate words of the flag name by dashes
+to do so, while the flag variable names are required to use underscores.
+
+Memory leaks reported by valgrind should be resolved by this release.
+This release fixes build errors with MS Visual Studio 2015.
+
+Please report any further issues with this release using the GitHub issue tracker.
