Release Timeline
================
-LLVM is released on a time based schedule --- roughly every 6 months. We do
-not normally have dot releases because of the nature of LLVM's incremental
-development philosophy. That said, the only thing preventing dot releases for
-critical bug fixes from happening is a lack of resources --- testers,
-machines, time, etc. And, because of the high quality we desire for LLVM
-releases, we cannot allow for a truncated form of release qualification.
+LLVM is released on a time based schedule --- with major releases roughly
+every 6 months. In between major releases there may be dot releases.
+The release manager will determine if and when to make a dot release based
+on feedback from the community. Typically, dot releases should be made if
+there are large number of bug-fixes in the stable branch or a critical bug
+has been discovered that affects a large number of users.
+
+Unless otherwise stated, dot releases will follow the same procedure as
+major releases.
The release process is roughly as follows:
* Finally, release!
+The release process will be accelerated for dot releases. If the first round
+of testing finds no critical bugs and no regressions since the last major release,
+then additional rounds of testing will not be required.

Similarly, **Release Candidate 2** would be named ``RC2`` and so on. This keeps
a permanent copy of the release candidate around for people to export and build
-as they wish. The final released sources will be tagged in the ``RELEASE_XY``
+as they wish. The final released sources will be tagged in the ``RELEASE_XYZ``
directory as ``Final`` (c.f. :ref:`tag`).
The Release Manager may supply pre-packaged source tarballs for users. This can

Community Testing
-----------------
#. During the remaining rounds of testing, only patches that fix critical
regressions may be applied.
+#. For dot releases all patches must mantain both API and ABI compatibility with
+ the previous major release. Only bugfixes will be accepted.
