(This change was actually made in Emacs 26.1, but was not called out
in its NEWS.)
** VC
*** VC support for Mercurial was improved.
Emacs now avoids invoking 'hg' as much as possible, for faster operation.
(This and the following changes were actually made in Emacs 26.1, but
were not called out in its NEWS.)
---
**** New vc-hg options.
The new option 'vc-hg-parse-hg-data-structures' controls whether vc-hg
will try parsing the Mercurial data structures directly instead of
running 'hg'; it defaults to t (set to nil if you want the pre-26.1
behavior).
The new option 'vc-hg-symbolic-revision-styles' controls how versions
in a Mercurial repository are presented symbolically on the mode line.
The new option 'vc-hg-use-file-version-for-mode-line-version' controls
whether the version shown on the mode line is that of the visited file
or of the repository working copy.
---
**** Display of Mercurial revisions in the mode-line has changed.
Previously, the mode line displayed the local number (1, 2, 3, ...) of
the revision. Starting with Emacs 26.1, the default has changed, and
it now shows the global revision number, in the form of its changeset
hash value. To get back the previous behavior, customize the new
option 'vc-hg-symbolic-revision-styles' to the value '("{rev}")'.
