Release Notes: Numerous bugs were fixed in this release. Most of the bugs are minor, but there was one bug in version 1.0.0 and earlier which has the potential to cause repository corruption, so it is strongly recommended that all users upgrade. There is an explanation of the issues related to this bug on the darcs wiki.
Release Notes: A way to configure the default values for options to darcs commands was added. darcs push and pull now default to pulling and pushing from the most recently accessed repository if you don't specify a repository. Several bugfixes were made, including a potentially nasty one in the merge code. Users should be sure to run darcs check on their repositories after upgrading to see if they're affected by the merge bug.
Release Notes: This release adds numerous memory, speed, and responsiveness improvements. It fixes rather serious bugs that showed up when dealing with an empty repo and when using the "mv" command.
