* Changes in Emacs 25.1
-** x-select-enable-clipboard is renamed gui-select-enable-clipboard.
-Additionally it now also applies to OSX and GNUstep.
+** Network security (TLS/SSL certificate validity and the like) is
+added via the new Network Security Manager (NSM) and controlled via
+the `network-security-level' variable.
+
+** 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
codeset is "UTF-8" (as in "en_US.UTF-8"). This is needed because
MS-Windows doesn't support UTF-8 as codeset in its locales.
+** New variable `ns-use-fullscreen-animation' controls animation for
+non-native NS fullscreen. The default is nil. Set to t to enable
+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'.
++++
+*** New vector QPattern.
** Lisp mode
*** Strings after `:documentation' are highlighted as docstrings.
*** C-x C-x in rectangle-mark-mode now cycles through the four corners.
*** `string-rectangle' provides on-the-fly preview of the result.
-+++
-** Macro `pcase' now supports vector qpattern.
-
** New font-lock functions font-lock-ensure and font-lock-flush, which
should be used instead of font-lock-fontify-buffer when called from Elisp.
** Macro `minibuffer-with-setup-hook' takes (:append FUN) to mean
appending FUN to `minibuffer-setup-hook'.
+** cl-lib
+*** New functions cl-fresh-line, cl-digit-char-p and cl-parse-integer.
+
** Calendar and diary
+++
`diary-chinese-insert-monthly-entry', `diary-chinese-insert-yearly-entry'.
+++
-*** Calendar can list and mark diary entries with Chinese dates.
+*** The calendar can now list and mark diary entries with Chinese dates.
See `diary-chinese-list-entries' and `diary-chinese-mark-entries'.
-*** The mode line of the calendar buffer will not be modified if
-`calendar-mode-line-format' is nil.
+---
+*** The option `calendar-mode-line-format' can now be nil,
+which means to do nothing special with the mode line in calendars.
+
+---
+*** Many items obsolete since at least version 23.1 have been removed.
+The majority were function/variable/face aliases, too numerous to list here.
+The remainder were:
+
+**** Functions `calendar-one-frame-setup', `calendar-only-one-frame-setup',
+`calendar-two-frame-setup', `european-calendar', `american-calendar'.
+
+**** Hooks `cal-menu-load-hook', `cal-x-load-hook'.
+
+**** Macro `calendar-for-loop'.
+
+**** Variables `european-calendar-style', `diary-face', `hebrew-holidays-{1,4}'.
+

+*** 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.
----

++++
+** 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.

bars on all existing and future frames.
+*** New function `toggle-horizontal-scroll-bar' to toggle horizontal

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
