** BibTeX mode
---
*** New user variables 'bibtex-BibTeX-aux-entry-alist',
'bibtex-biblatex-aux-entry-alist', 'bibtex-BibTeX-aux-opt-alist',
and 'bibtex-biblatex-aux-opt-alist' facilitate the customization of
BibTeX and biblatex entries. These variables now support the definition
of aliases that inherit the definition of another entry.
---
*** The user variable 'bibtex-user-optional-fields' has been renamed
to 'bibtex-aux-opt-alist'. The old name is an obsolete alias.
---
*** The user variable 'bibtex-include-OPTkey' is now obsolete and
its default is nil. Use 'bibtex-aux-opt-alist' instead.
---
*** New user option 'bibtex-entry-ask-for-key'.
