\section{Background}

CVS uses tags to collectively label a particular set of revisions of a particular set of files. With a tag, one may easily request all the revisions of all the files that correspond to something meaningful, such as an official release of a project.

There are two kinds of tags provided by CVS. First is the release tag that simply marks a set of revisions as belonging together as a unit. Each release of a project should be tagged with a release tag. Other development milestones may also receive a release tag. Release tags are useful for marking any point in development that will be useful to return to or compare against.

The second kind of tag is a branch tag. It does not mark a single revision of a file, but an entire branch of development of a file. Branch tags are the means by which different working directories can track different branches of development.

A tag may be used in a CVS repository only once, so we must keep track of what tags have already been used, and what they mean. The remaining sections of this TIP record the tags in use. This TIP should be kept up to date by adding any new tags here as they are added to the CVS repository.

\section{Branch Tags --- Official Development}

The following branch tags label branches of development from which releases of Tcl/Tk are generated:
\begin{itemize}
\item{}
\textit{HEAD} --- current development of new features; spawns future alpha and beta releases.
\item{}
\textit{core-8-5-branch} --- bug fix branch; spawns 8.5.\textit{X} releases after 8.5.2.
\item{}
\textit{core-8-4-branch} --- bug fix branch; spawns 8.4.\textit{X} releases after 8.4.2.
\end{itemize}

\section{Branch Tags --- Features}

The following branch tags label branches on which features are being developed and tested. No releases of Tcl/Tk will be spawned from these branches. As the features mature, they will be merged onto the HEAD branch, or they may be rejected.
\begin{itemize}
\item{}
\textit{core-8-4-win-speedup} (Tk) --- Work on improving performance of Tk on the Windows platforms.
\item{}
\textit{tip-59-implementation} (Tcl) --- For coordinating between Andreas Kupries and the platform maintainers on implementing \cite{tip59}.
\item{}
\textit{mod-8-3-4-branch} (Tcl) --- Contains the modularization work done by ActiveState for Cisco. Not for public modification.
\item{}
\textit{dgp-refactor} (Tcl) --- Various refactoring exercises.
\item{}
\textit{kennykb-numerics-branch} (Tcl) --- Explorations into improving Tcl's numeric properties, including support for large integers and rationals, and improvements to Tcl's floating point conversions.
\item{}
\textit{msofer-wcodes-branch} (Tcl) --- Experimental features for the bytecode engine.
\item{}
\textit{tip-257-implementation-branch} (Tcl) --- For development of the implementation of \cite{tip257}. Branch root version at the tag \textit{tip-257-implementation-branch-root}.
\item{}
\textit{tip-278-branch} (Tcl) --- Work on \cite{tip278}.
\item{}
\textit{core-stabilizer-branch} (Tcl/Tk) --- Branch where the version number is bumped to the next level of stability above the HEAD for advance testing of issues that might arise when the HEAD is declared more stable.
\item{}
\textit{tip-162-branch} (Tcl) --- Work on \cite{tip162}. Includes extreme windows channel driver rewrite. Maintained by davygrvy@pobox.com
\end{itemize}

\section{Dead Branches}

The following branch tags label branches that are no longer being developed. Some are old official branches from which releases are no longer being spawned. Others are feature development branches that have been merged into an official branch, or rejected.
\begin{itemize}
\item{}
\textit{macosx-8-4-branch} --- Branch used during MacOSX porting work. Merged into 8.4.0.
\item{}
\textit{dkf-64bit-support-branch} (Tcl) --- Work on supporting 64-bit numbers, particularly on 32-bit platforms (including large file support.) See \cite{tip72} for overview. Results merged into HEAD.
\item{}
\textit{kennykb-tip-22-33} (Tcl) --- Work on implementing the changes described in \cite{tip22} and \cite{tip33}. Abandoned.
\item{}
\textit{dgp-privates-into-namespace} (Tk) --- Work on moving Tk's private commands and variables into the ::tk namespace and its children (see \cite{tip44}.) Merged into Tk 8.4a3.
\item{}
\textit{core-8-3-1-io-rewrite} (Tcl) --- Work rewriting Tcl's IO Channels to correct problems with the implementation of stacked channels. Merged into Tcl 8.3.2 and Tcl 8.4a2.
\item{}
\textit{daves-chop-branch} (Tcl) --- Attempts to modularize subsystems so they can be easily removed at compile-time. First step towards a 'tinytcl' on the HEAD rather than starting with an older version. (maintained by davygrvy@pobox.com)
\item{}
\textit{daves-mk-branch} (Tcl) --- On-going work to improve the native windows makefiles. One top-root makefile.win will serve as the starting point for MSVC++, BCC, and Watcom. Extreme use of shared info will highlight this new system. This is not TEA --- this is anti-TEA. (maintained by davygrvy@pobox.com)
\item{}
\textit{core-8-3-1-branch} --- Spawned Tcl/Tk 8.3.X releases.
\item{}
\textit{core-8-2-1-branch} --- Spawned Tcl/Tk 8.2.X releases.
\item{}
\textit{core-8-1-branch-old} --- Spawned Tcl/Tk 8.1bX releases.
\item{}
\textit{dev-stubs-branch}, \textit{dev-8-1-stubs-branch} --- Two branches on which the stubs interfaces were developed. Merged into Tcl 8.1.
\item{}
\textit{msofer-bcEngine} (Tcl) --- Work on improving performance of the bytecode engine.
\end{itemize}
