The Mercurial Sprint, spring 2010 edition

Things that got done

UI: many error messages have been improved
mq improvements: parent nodes, UI cleanup, -Q for versioned users, better error messages
named branches: heads changes, push/pull/in/out per branch, better error messages
work on the Python conversion, hgsubversion release
work on support for git subrepos
improvements for HTTP protocol support
code to implement progress bars
rebase --detach (expected behavior), new 'adapt' command soon
WiX-based installers hg and THG
support for SSL server certificates
better import of multiple patches

more efficient incoming/outgoing (changelog-only, improved discovery)
better debugging tools (condensed DAG creation/display)
useful discussions on narrow/shallow clones (and punching)
pbranch: use rebase --detach, integration with review/lbranch/overlay
parent deltas
basic support for transferring bookmarks
stream improvements: future hash types support, progress support
getting interactive hunk selection into core (needs in-memory patching)
selectively include/exclude help details (examples, background)
continuous integration using tools from Logilab
work on a scripting mode (disable customizations; for use with MercurialEclipse, emacs' vc-hg)
work on output annotation (better support for colors, GUI hooks)
improvements to the hg-review extension
