Hi everybody,
The third pre-release of darcs 2.1 is now available at

Since the last pre-release, we have resolved two of the items on our
work list and a recently discovered darcs 2 bug.

On the other hand, we have discovered a new regression from darcs 2.0.2
and some performance issues in our recent work for issue971.  We are
confident that we can resolve these within the upcoming week, but since
regressions are involved, I think it might be prudent to delay the
release so that we at least have one week to test these changes.  At the
very latest, darcs 2.1 should be released on 17 October, but I hope we
will be able to get it out soon after the tenth.

We are now very close to the finish line.  More news in a week!

Upcoming release schedule
2008-10-10: darcs 2.1.0pre4 
2008-10-17: darcs 2.1.0

Work remaining
* Backing out http://bugs.darcs.net/issue971 (Petr Ročkai)
  We have observed a performance regression in the newer, more robust
  version of the darcs repair code and will be postponing this feature
  for next release.  The work for this week consists of undoing the
  relevant changes and auditing the undo.
* http://bugs.darcs.net/issue1095
  Darcs sometimes crashes in darcs send.  It is clear to us why the
  crash happens and how to fix it.  The work for this week consists
  of creating a minimal test case for our regression testing suite
  and implementing the relevant changes.

* http://bugs.darcs.net/issue1026
  Improve the error messages for 'bug in get_extra' errors, which can
  happen if darcs is fooled into thinking that two patches are the same.

Changes since the last pre-release
* Bug Fix: Eliminate an error merging repeated conflicts in darcs-2
  repositories (issue1043, David Roundy)

* New Feature: Hide 'Ignore-this:' lines which will be generated by future
  versions of darcs to prevent patch-id collisions. (issue1102, Eric Kow,
  David Roundy)

* Bug Fix: Support darcs repositories which have symbolic links in their
  paths (issue1078, Dmitry Kurochkin)

* Bug Fix: Make ssh connection sharing (darcs transfer-mode) work with
  old-fashioned repositories (issue1003, David Roundy)
