Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Implement revlogng. revlogng results in smaller indexes, can address larger data files, and supports flags and version numbers. By default the original revlog format is used. To use the new format, use the following .hgrc field: [revlog] # format choices are 0 (classic revlog format) and 1 revlogng format=1
