Changelog
hg log
The changelog is part of a Mercurial repository. It contains all changesets of a repository and is stored in revlog format. For each changeset of the repository, there is exactly one file revision in the revlog file.
The changelog is stored in .hg/store/00changelog.i and optionally .hg/store/00changelog.d in the repository. Note that 00changelog.d may be missing, because Mercurial merges its content right into the 00changelog.i for small changelogs (see RevlogNG).
