Historically CMake used three version components for the feature level.
We released new features while incrementing only the third version
component. Since commit v2.8.2~105^2~4 (New version scheme to support
branchy workflow, 2010-04-23) we used the fourth version component for
bug-fix releases and the development date:
<major>.<minor>.<patch>[.<tweak>][-rc<n>] = Release
<major>.<minor>.<patch>.<date>[-<id>] = Development
This solidified use of three components for the feature level, and was
necessary to continue releasing 2.x versions because:
* Some existing projects performed floating-point comparisons of
${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION} to 2.x numbers
so ``x`` could never be higher than 9.
* Version 2.9.<date> was used briefly in post-2.8.0 development in
CVS prior to the transition to Git, so using it in releases may
have caused confusion.
Now that we are moving to 3.x versions, these two restrictions go away.
Therefore we now change to use only two components for the feature
level and use the scheme:
<major>.<minor>.<patch>[-rc<n>] = Release
<major>.<minor>.<date>[-<id>] = Development
When building boost with an alternate namespace the libraries generated
will have a different naming convention. This is often done to ensure
no symbol conflicts with external libraries built against a different
version of boost. If the namespace used is "myprivateboost::" instead
of "boost::" then the libraries built will be named myprivateboost_foo
instead of boost_foo. Add an option to specify a custom namespace used
to alter the library names that get searched for.
Manually read through version control history since the 2.8.12.2
release and write release notes for important user-facing changes.

Add a release/dev.txt file and include it from release/index.rst in
development versions. Add a "Changes Since Release" section with a
toctree that globs adjacent "dev/*" documents. Add a sample topic
document explaining how topic-specific release note documents work.
This approach will allow developers to write release notes for their
changes as they are made. The release manager may then consolidate and
organize the notes for a specific release version.
Add a release/index.rst document titled "CMake Release Notes" to hold
the toctree for release notes. Add a "Release Notes" section to the
top-level html document index to link to the new document.
