First draft of our 2010-05 HCAR report.
Note that you can edit this directly if you want:

Basically, I've been leaving the first and last paragraph
intact and modifying the middle section which reports on
progress in the last 6 months.
Darcs is a distributed revision control system written in Haskell. In
Darcs, every copy of your source code is a full repository, which allows for
full operation in a disconnected environment, and also allows anyone with
read access to a Darcs repository to easily create their own branch and
modify it with the full power of Darcs' revision control. Darcs is based on
an underlying theory of patches, which allows for safe reordering and
merging of patches even in complex scenarios. For all its power, Darcs
remains a very easy to use tool for every day use because it follows the
principle of keeping simple things simple.
Our most recent major release, Darcs 2.4, was in January 2010.
It provides faster repository-local operations, a new interactive hunk
editing feature among other bug fixes and features. For our next
release, we hope to continue the trend of improving Darcs performance:
\item Better support for long histories: Petr Rockai has begun work
(originally started by David Roundy) to make Darcs handle
long histories in hashed repositories. If you tag your
repositories regularly, operations that add or remove patches
to Darcs should take O(1) time instead of O(N) with respect to
the number of the patches in your history.
\item Faster Darcs annotate: Benedikt Schmidt has nearly completed
his work on a new ``patch index'' feature which we hope to make
darcs annotate considerably faster. He also plans to overhaul
the user interface to provide more human-readable output.
These changes and more will appear in the upcoming Darcs 2.5 release,
scheduled for July 2010. Also, we are excited to report that a Darcs
project has been accepted for the 2010 Google Summer of Code. Alexey
Levan will be working to improve Darcs performance over networks.
Meanwhile, we still have a lot progress to make and are always open to
contributions. Haskell hackers, we need your help!
