* Changes in Emacs 25.1
-** x-select-enable-clipboard is renamed gui-select-enable-clipboard.
-Additionally it now also applies to OSX and GNUstep.
+** C-h l now also lists the commands that were run.
+
+** The new M-s M-w key binding uses eww to search the web for the
+text in the region.
+
+** M-x suggests shorthands and ignores obsolete commands for completion.
+** x-select-enable-clipboard is renamed select-enable-clipboard.
+x-select-enable-primary and renamed select-enable-primary.
+Additionally they both now apply to all systems (OSX, GNUstep, Windows, you
+name it), with the proviso that on some systems (e.g. Windows)
+select-enable-primary is ineffective since the system doesn't
+have the equivalent of a primary selection.
+++
** terpri gets an optional arg ENSURE to conditionally output a newline.
++++
+** New macro `define-advice'.
+
** `insert-register' now leaves point after the inserted text
when called interactively. A prefix argument toggles this behavior.
** New var `truncate-string-ellipsis' to choose how to indicate truncation.
----
-** The default value of `history-length' has increased to 100.
-
+++
** The new variable `term-file-aliases' replaces some files from lisp/term.
The function `tty-run-terminal-initialization' consults this variable
animation when entering and leaving fullscreen. For native OSX fullscreen
this has no effect.
+*** A new text property `inhibit-read-only' can be used in read-only
+buffers to allow certain parts of the text to be writable.
+
\f
* Editing Changes in Emacs 25.1
+** New minor mode global-eldoc-mode is enabled by default.
+
** Emacs now supports "bracketed paste mode" when running on a terminal
that supports it. This facility allows Emacs to understand pasted
chunks of text as strings to be inserted, instead of interpreting each
paste experience similar to that under a window system, and significant
performance improvements when pasting large amounts of text.
+** Emacs now supports the latest version of the UBA.
+The Emacs implementation of the Unicode Bidirectional Algorithm (UBA)
+was updated to support all the latest additions and changes introduced
+in Unicode Standard versions 6.3 and 7.0, and a few changes suggested
+for Unicode 8.0. This includes full support for directional isolates
+and the Bidirectional Parentheses Algorithm (BPA) specified by these
+Unicode standards.

\f
* Changes in Specialized Modes and Packages in Emacs 25.1
+** ido
+*** New command `ido-bury-buffer-at-head' bound to C-S-b
+Bury the buffer at the head of `ido-matches', analogous to how C-k
+kills the buffer at head.
+
+** Minibuffer
+
+*** You can use <up> and <down> keys to move point in the multi-line
+minibuffer just as in an ordinary buffer. Only when point moves over
+the bottom/top of the minibuffer it goes to the next/previous history
+element. The new commands bound to <up> and <down> in the minibuffer:
+`next-line-or-history-element' and `previous-line-or-history-element'.
+
+** Search and Replace
+
+*** 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
+and TO are the original text and its replacement, and SEP is an arrow
+string defined by the new variable `query-replace-from-to-separator'.
+To select a prior replacement, type `M-p' until the desired
+replacement appears in the minibuffer, and then exit the minibuffer by
+typing RET.
+
+** Calc
++++
+*** If `quick-calc' is called with a prefix argument, insert the
+result of the calculation into the current buffer.
** ElDoc
*** New minor mode global-eldoc-mode
*** eldoc-documentation-function now defaults to nil
+** eww
+
+*** A new command `R' (`eww-readable') will try do identify the main
+textual parts of a web page and display only that, leaving menus and
+the like off the page.
+
+*** You can now use several eww buffers in parallel by renaming eww
+buffers you want to keep separate.
+
+*** Partial state of the eww buffers (the URIs and the titles of the
+pages visited) is now preserved in the desktop file.
+
+*** `eww-after-render-hook' is now called after eww has rendered
+the data in the buffer.
+
+** Message mode
+
+*** text/html messages that contain inline image parts will be
+transformed into multipart/related messages before sending.
+
** pcase
*** New UPatterns `quote' and `app'.
*** New UPatterns can be defined with `pcase-defmacro'.
**** Variables `european-calendar-style', `diary-face', `hebrew-holidays-{1,4}'.
+**** The nil and list forms of `diary-display-function'.
+
** New ERT function `ert-summarize-tests-batch-and-exit'.
+---
+** `Info-fontify-maximum-menu-size' can be t for no limit.
+
---
** ntlm.el has support for NTLM2.
** In sh-mode, you can now use `sh-shell' as a file-local variable to
specify the type of shell in use (bash, csh, etc).
-** The URL package accepts now the protocols "ssh", "scp" and "rsync".
+** URL
+
+*** The URL package accepts now the protocols "ssh", "scp" and "rsync".
When `url-handler-mode' is enabled, file operations for these
protocols as well as for "telnet" and "ftp" are passed to Tramp.
+*** The URL package allows customizing the `url-user-agent' string.
+The new `url-user-agent' variable can be customized to be a string or
+a function.
+
+*** The new interface variable `url-request-noninteractive' can be used
+to specify that we're running in a noninteractive context, and that
+we should not be queried about things like TLS certificate validity.
+
** Tramp
*** New connection method "nc", which allows to access dumb busyboxes.
** VC and related modes
+*** The new command vc-region-history shows the log+diff of the active region.
+
*** New option `vc-annotate-background-mode' controls whether
the color range from `vc-annotate-color-map' is applied to the
background or to the foreground.
*** New custom variable `tex-print-file-extension' to help users who
use PDF instead of DVI.
-** Obsolete packages
+** whitespace-mode: new 'big-indent style highlighting too much indentation.
+By default, 32 spaces and four TABs are considered to be too much but
+`whitespace-big-indent-regexp' can be configured to change that.
----
-*** gulp.el
+** tildify: `tildify-space-string', `tildify-pattern', and
+`tildify-foreach-region-function' variables added making
+`tildify-string-alist', `tildify-pattern-alist', and
+`tildify-ignored-environments-alist' variables (as well as a few
+helper functions) obsolete.
----
-*** crisp.el, tpu-edt.el, ws-mode.el
-These emulations of old editors are believed to be no longer relevant
- - contact emacs-devel@gnu.org if you disagree.
+** Obsolete packages
---
-*** vi.el, vip.el (try M-x viper instead)
+*** gulp.el

\f
* Incompatible Lisp Changes in Emacs 25.1
\f
* Lisp Changes in Emacs 25.1
+** New function macroexpand-1 to perform a single step of macroexpansion.
+
** Some "x-*" were obsoleted:
*** x-select-text is renamed gui-select-text.
*** x-selection-value is renamed gui-selection-value.
*** x-get-selection-value is renamed to gui-get-primary-selection.
*** x-set-selection is renamed to gui-set-selection
-** call-process-shell-command and process-file-shell-command

-
** New function `alist-get', which is also a valid place (aka lvalue).
** New function `funcall-interactively', which works like `funcall'
*** New macros `thread-first' and `thread-last' allow threading a form
as the first or last argument of subsequent forms.
++++
+** Time-related changes:
+
+*** Time-related functions now consistently accept numbers
+(representing seconds since the epoch) and nil (representing the
+current time) as well as the usual list-of-integer representation.
+Affected functions include `current-time-string', `current-time-zone',
+`decode-time', `float-time', `format-time-string', `seconds-to-time',
+`time-add', `time-less-p', `time-subtract', `time-to-day-in-year',
+`time-to-days', and `time-to-seconds'.

+been obsoleted.
+
+*** `calendar-next-time-zone-transition', `time-add', and
+`time-subtract' no longer return time values in the obsolete and
+undocumented integer-pair format. Instead, they return a list of two
+integers.
+
\f
* Changes in Frames and Windows Code in Emacs 25.1
*** New buffer-local variables `horizontal-scroll-bar' and
`scroll-bar-height'.
++++
** The height of a frame's menu and tool bar are no more counted in the
frame's text height. This means that the text height stands only for
the height of the frame's root window plus that of the echo area (if
and menu bars (like in the Gtk builds) but has now been extended to all
builds.
++++
** Frames now do not necessarily preserve the number of columns or lines
they display when setting default font, menu bar, fringe width, or
scroll bars. In particular, maximized and fullscreen frames are
specific frame does not resize that frame in order to preserve the
number of columns or lines it displays.
+** Tearoff menus and detachable toolbars for Gtk+ has been removed.
+Those features have been deprecated in Gtk+ for a long time.
+
\f
