* Installation Changes in Emacs 24.5
++++
+** Building Emacs now requires C99 or later.
+
+** Building Emacs now requires GNU make.
+
+** By default, Emacs no longer works on IRIX. We expect that Emacs
+users are not affected by this, as SGI stopped supporting IRIX in
+December 2013. If you are affected, please send a bug report. You
+should be able to work around the problem either by porting the Emacs
+undumping code to GCC under IRIX, or by configuring --with-wide-int,
+or by sticking with Emacs 24.4.
+
+---
+** The configure option `--with-pkg-config-prog' has been removed.
+Use './configure PKG_CONFIG=/full/name/of/pkg-config' if you need to.
+
\f
* Startup Changes in Emacs 24.5
---
** 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
+when deciding what terminal-specific initialization code to run.
+
+---
+** New variable `system-configuration-features', listing some of the
+main features that Emacs was compiled with. This is mainly intended
+for use in Emacs bug reports.
+
\f
* Editing Changes in Emacs 24.5
+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
+character in the pasted text as actual user input, resulting in a
+paste experience similar to that under a window system and significant
+performance improvements when pasting large amounts of text.
+
\f
* Changes in Specialized Modes and Packages in Emacs 24.5
---
** The Rmail commands d, C-d and u now handle repeat counts
to delete or undelete multiple messages.
+
+** Calendar and diary
+
++++
+*** New commands to insert diary entries with Chinese dates:
+`diary-chinese-insert-anniversary-entry' `diary-chinese-insert-entry'
+`diary-chinese-insert-monthly-entry'
+`diary-chinese-insert-yearly-entry'
+
++++
+*** Calendar can list and mark diary entries with Chinese dates:
+`diary-chinese-list-entries' and `diary-chinese-mark-entries'.
+
+** 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.
+
+** Obsolete packages
+
+---
+*** gulp.el

* New Modes and Packages in Emacs 24.5
\f
* Incompatible Lisp Changes in Emacs 24.5
+** window-configurations do not record the buffers's marks any more.
+
+** inhibit-modification-hooks now also inhibits lock-file checks as well as
+active region handling.
+
+** deactivate-mark is now buffer-local.
+
+** cl-the now asserts that its argument is of the given type.
+
\f
* Lisp Changes in Emacs 24.5
+** New function `function-put' to use instead of `put' for function properties.
+
++++
+** New properties that can be specified with `declare':
+*** (interactive-only INSTEAD), tells to use INSTEAD for non-interactive use.
+*** (pure VAL), if VAL is non-nil, indicates the function is pure.
+*** (side-effect-free VAL), if VAL is non-nil, indicates the function does not
+have side effects.
+
++++
+** New macro `with-file-modes', for evaluating expressions with default file
+permissions set to temporary values (e.g., for creating private files).
+
+** You can access the slots of structures using `cl-struct-slot-value'.
+
\f
* Changes in Emacs 24.5 on Non-Free Operating Systems
** In keymaps where SPC scrolls forward, S-SPC now scrolls backward.
This affects View mode, etc.
++++
+** The default value of `make-backup-file-name-function' is no longer nil.
+Instead it defaults to a function that does what the nil value used to.
+
** Help changes

*** `electric-indent-mode' is now enabled by default.
-E.g., typing RET reindents the current line and indents the new line.
-`C-j' inserts a newline but does not indent.
+Typing RET reindents the current line and indents the new line.
+`C-j' inserts a newline but does not indent. In some programming modes,
+additional characters are electric (eg `{').
+++
*** New buffer-local `electric-indent-local-mode'.

** New Dired minor mode `dired-hide-details-mode' toggles whether details,
-such as file ownership or permissions, are visible.
+such as file ownership or permissions, are visible in Dired buffers.
+See the new options `dired-hide-details-hide-symlink-targets' and
+`dired-hide-details-hide-information-lines' for customizing what to hide.

** You can enable ElDoc inside the `eval-expression' minibuffer with:
** The cars of the elements in `interpreter-mode-alist' are now
treated as regexps rather than literal strings.
+---
+** Overlay priority does not have to be nil or a non-negative integer.
+Overlay priority can be other kinds of Lisp objects. We didn't yet
+decide whether other types of values are stable enough, and therefore
+don't feel it's right to document them. For now, don't assume in your
+code that the values of overlay priority can only be either nil or an
+integer, always test them with an appropriate predicate to be one or
+the other.

** The second argument of `eval' can now specify a lexical environment.

`visited-file-modtime'.
-** Autorevert changes
+** Revert and Autorevert changes
+
++++
+*** The default values of `buffer-stale-function', `revert-buffer-function',
+and `revert-buffer-insert-file-contents-function' are no longer nil.
+Instead they default to functions that do what the nil value used to.
+
++++
+*** `buffer-stale-function' is now used for buffers visiting files too.
