darcs

Most of the functionality provided by the old
"push" command has been split into two commands:
"send" and "push". Win32 support has been
improved, including support for sending patches by
email via MAPI, the standard Windows email
interface. Along with these major changes, a
number of bugfixes and performance improvements
were made.

A couple of minor, but annoying, bugs that made it
into version 0.9.16 were fixed.

Support was added for per-user preference setting
which can be overridden by the existing
per-repository preferences. Support was added for
multiple-choice flags (such as --summary and
--no-summary), so users can choose either one as
the default option and then override it on the
command line. File permissions in the working
direcotry are now preserved. A few minor bugs were
fixed.

The repository format transition begun in darcs 0.9.14 has moved to the
next stage. Also, a problem with text files lacking trailing newlines
has been fixed. Both of these changes are dealt with by the convert-repo
program. New repair, annotate, and rollback commands have been added,
and darcs mv has been improved to better match the behavior of the
ordinary shell mv. A number of performance improvements and minor
bugfixes have been implemented, as well.

The user interface was rewritten, allowing the
user to return to previous prompts. A transition
to a new repository format was started (this will
take two more releases to complete). Other changes
include the new unrevert command, automatic
detection of binary files that contain '\0' or ^Z,
and a --summary option for whatsnew. darcs can now
be called in subdirectories of a repository.
Miscellaneous bugfixes were made.
