-** Emacs can now load shared/dynamic libraries (modules) that expose a
-C interface. Such modules can provide additional functions or
-otherwise interact with Emacs just like Lisp code. Modules have to
-export a function `emacs_module_init' and conform to the API laid out
-in emacs-module.h. Modules are disabled by default and need to be
-enabled using the --with-modules configure flag. They are
-experimental and subject to change.
+** Emacs can now load shared/dynamic libraries (modules).
+A dynamic Emacs module is a shared library that provides additional
+functionality for use in Emacs Lisp programs, just like a package
+written in Emacs Lisp would. The functions `load', `require',
+`load-file', etc. were extended to load such modules, as they do with
+Emacs Lisp packages. The new variable `module-file-suffix' holds the
+system-dependent value of the file-name extension (`.so' on Posix
+hosts) of the module files.
+
+A module should export a C-callable function named
+`emacs_module_init', which Emacs will call as part of the call to
+`load' or `require' which loads the module. It should also export a
+symbol named `plugin_is_GPL_compatible' to indicate that its code is
+released under the GPL or compatible license; Emacs will refuse to
+load modules that don't export such a symbol.
+
+If a module needs to call Emacs functions, it should do so through the
+API defined and documented in the header file `emacs-module.h'. Note
+that any module that provides Lisp-callable functions will have to use
+Emacs functions such as `fset' and `funcall', in order to register its
+functions with the Emacs Lisp interpreter.
+
+Modules can create `user-ptr' Lisp objects that embed pointers to C
+struct's defined by the module. This is useful for keeping around
+complex data structures created by a module, to be passed back to the
+module's functions. User-ptr objects can also have associated
+"finalizers" -- functions to be run when the object is GC'ed; this is
+useful for freeing any resources allocated for the underlying data
+structure, such as memory, open file descriptors, etc. A new
+predicate `user-ptr-p' returns non-nil if its argument is a `usr-ptr'
+object.
+
+Loadable modules in Emacs are an experimental feature, and subject to
+change in future releases. For that reason, their support is disabled
+by default, and must be enabled by using the `--with-modules' option
+at configure time.

* Editing Changes in Emacs 25.1
** Successive single-char deletions are collapsed in the undo-log just like
successive char insertions.
++++
+** New command `comment-line' bound to `C-x C-;'.
+
** Unicode names entered via C-x 8 RET now use substring completion by default.
** C-x 8 now has shorthands for these chars: ‐ ‑ ‒ – — ― ‘ ’ “ ” † ‡ • ′ ″

* Changes in Specialized Modes and Packages in Emacs 25.1
+** Checkdoc
+
++++
+*** New command `checkdoc-package-keywords' checks if the
+current package keywords are recognized. Set the new option
+`checkdoc-package-keywords-flag' to non-nil to make
+`checkdoc-current-buffer' call this function automatically.
+
++++
+*** New function `checkdoc-file' checks for style errors.
+It's meant for use together with `compile':
+emacs -batch --eval "(checkdoc-file \"subr.el\")"
+
** New function `bookmark-set-no-overwrite' bound to C-x r M.
It raises an error if a bookmark of that name already exists,
unlike `bookmark-set' which silently updates an existing bookmark.
** Search and Replace
++++
+*** New user option `search-default-regexp-mode'
+specifies the default mode for I-search.
+
++++
+*** `isearch' and `query-replace' can now perform character folding in matches.
+Isearch does that by default, while `query-replace' will do that if
+the new variable `replace-character-fold' is customized to a non-nil
+value. This is analogous to case folding, but instead of disregarding
+case variants, it disregards wider classes of distinctions between
+similar characters. (Case folding is a special case of character
+folding.) This means many characters in the search string will match
+entire groups of characters instead of just themselves.
+
+For instance, the " will match all variants of double quotes (like “
+and ”), and the letter a will match all of its accented cousins, even
+those composed of multiple characters, as well as many other symbols
+like ℀, ℁, ⒜, and ⓐ.
+
++++
+*** New function `character-fold-to-regexp' can be used
+by searching commands to produce a regexp matching anything that
+character-folds into STRING.
+
++++
+*** The new M-s M-w key binding uses eww to search the web for the
+text in the region. The search engine to use for this is specified by
+the customizable variable `eww-search-prefix'.
+
++++
*** Query-replace history is enhanced.
When query-replace reads the FROM string from the minibuffer, typing
`M-p' will now show previous replacements as "FROM SEP TO", where FROM
allow overriding the regular expression that recognizes the ldapsearch
command line's password prompt.
+EUDC's BBDB backend now supports BBDB 3.

* Incompatible Lisp Changes in Emacs 25.1
+---
+** `setq' and `setf' must now be called with an even number of
+arguments. The earlier behavior of silently supplying a nil to the
+last variable when there was an odd number of arguments has been
+eliminated.
+
** `syntax-begin-function' is declared obsolete.
Removed font-lock-beginning-of-syntax-function and the SYNTAX-BEGIN
slot in font-lock-defaults.
