This is a regularly-scheduled feature release. A new core graft command that lets you copy changesets from one branch to another, while using the merge machinery to resolve conflicts. A new standard extension called largefiles lets you handle very large files (hundreds of megabytes) with Mercurial. The files are stored outside Mercurial and are downloaded on demand when you update. Subrepositories were changed in this release: commit will now abort when there are uncommitted changes in subrepos. Use the -S option to recurse. Various bugs were fixed.
This is a major feature release that introduces "filesets". This is a powerful query language that can be used with all commands to select files based on their repository state and their content. Another new feature is the Mercurial command server. The server keeps running after executing each command, and so the startup overhead is removed. A new experimental "generaldelta" format was introduced. When enabled on a server, this can reduce the size of new clones drastically, regardless of the client version used. Many other small enhancements were made and bugs were fixed.
This is a scheduled bugfix release. The hgweb script was fixed to handle index generation for invalid paths. Handling of symlinks was improved for the keyword extension. Several bugfixes were made to subrepositories: removal of read-only Subversion files on Windows was fixed, a missing .hgsub file is now handled as if it was removed, empty directories are pruned when a Subversion subrepository is removed, a Python 2.6 bug was fixed for subrepositories. The MQ extension was fixed to ignore subrepositories. Support for generating x64 native MSI packages was added.
This release has improved behavior for named branches with the heads command and a new XML output template for logs. It can import multiple patches from email messages, mboxes, files, and URLs. A new patch.eol=auto option will let users ignore patch line-endings while preserving target file endings. The clone, bundle, incoming, outgoing, pull, and push commands now have a -b/--branch option. Basic Subversion support was added to subrepos. Support for SSL server certificates was added and IPv6 support was improved. The HGPLAIN environment variable makes output more stable for scripts.
This is a minor release. It fixes two regressions since 1.4: prepush logic when push creates new heads, and truncation of patch names in qseries. A new extension called schemes is included. Various other small bug and documentation fixes was made.
