* Changes in Specialized Modes and Packages in Emacs 23.1
** Abbrev has been rewritten in Elisp and extended with more flexibility.
++++
*** New functions: abbrev-get, abbrev-put, abbrev-table-get, abbrev-table-put,
abbrev-table-p, abbrev-insert, abbrev-table-menu.
++++
*** Special hook `abbrev-expand-functions' obsoletes `pre-abbrev-expand-hook'.
++++
*** `make-abbrev-table', `define-abbrev', `define-abbrev-table' all take
extra arguments for arbitrary properties.
++++
*** New variable `abbrev-minor-mode-table-alist'.
++++
*** `local-abbrev-table' can hold a list of abbrev-tables.
++++
*** Abbrevs have now the following special properties:
`:count', `:system', `:enable-function', `:case-fixed'.
++++
*** Abbrev-tables have now the following special properties:
`:parents', `:case-fixed', `:enable-function', `:regexp',
`abbrev-table-modiff'.
This variable was only used by call-process-region, which now uses
temporary-file-directory instead.
+** The COUNT and SYSTEM-FLAG arguments to define-abbrev have been
+removed. The function now takes extra arguments for specifying
+arbitrary abbrev properties.
