Darcs 2.4 release announcement

+February 27, 2010 - The darcs team is proud to announce the immediate availability of darcs 2.4. +darcs 2.4 contains many improvements and bugfixes compared to darcs 2.3.1. +Highlights are the faster operation of record, revert and related commands, +and the experimental interactive hunk editing. +

+ +

+The easiest way to install darcs is using the Haskell Platform [1]. If you +have installed the Haskell Platform or cabal-install, you can install this +beta release by doing:

+ +

+  $ cabal update
+  $ cabal install --reinstall darcs
+

+ +

Alternatively, you can download the tarball from +http://darcs.net/releases/darcs-2.4.tar.gz, and build it by hand as +explained in the README file.

+ +

Interactive hunk editing

+ +

+To try out interactive hunk editing, press 'e' when you are prompted with a +hunk patch by 'darcs record'. You will then be shown an editor screen in which +you can edit the state you want to record between the last two ruler lines. +

+ +

+You can find more information about the hunk editing feature on +the hunk editor wiki page. +

+ +

Performance

+darcs in its current form does not perform very well on huge repositories. In +order to systematically address this issue, and to catch performance +regressions, we have started a darcs benchmarking project. You can find +benchmarks of darcs performance in many different situations on +the benchmarks wiki page. On this other wiki page, you will find graphs of the benchmark results on a Windows Vista machine. +

+ +

+On that page, you will also find instructions on how to run your own darcs +benchmarks. +

+ +

Reporting bugs

+ +

+If you have an issue with darcs 2.4, you can report it via the web on +http://bugs.darcs.net/ . You can also report bugs by email to bugs@darcs.net. +

+ +
