* Changes in Emacs 21.4
+ ** The max size of buffers and integers has been doubled.
+ On 32bit machines, it is now 256M (i.e. 268435455).
+
+ ** Under XFree86 4, the display table is modified so that `' is
+ displayed as balanced quotes, not the ASCII glyphs whose shape has
+ been changed generally in the XFree86 fonts.
+
+ +++
+ ** The -f option, used from the command line to call a function,
+ now reads arguments for the function interactively if it is
+ an interactively callable function.
+
+
+ ** sql changes.
+
+ *** The variable `sql-product' controls the highlightng of different
+ SQL dialects. This variable can be set globally via Customize, on a
+ buffer-specific basis via local variable settings, or for the current
+ session using the new SQL->Product submenu. (This menu replaces the
+ SQL->Highlighting submenu.)
+
+ The following values are supported:
+
+ ansi ANSI Standard (default)
+ db2 DB2
+ informix Informix
+ ingres Ingres
+ interbase Interbase
+ linter Linter
+ ms Microsoft
+ mysql MySQL
+ oracle Oracle
+ postgres Postgres
+ solid Solid
+ sqlite SQLite
+ sybase Sybase
+
+ The current product name will be shown on the mode line following the
+ SQL mode indicator.
+
+ The technique of setting `sql-mode-font-lock-defaults' directly in
+ your .emacs will no longer establish the default highlighting -- Use
+ `sql-product' to accomplish this.
+
+ *** The function `sql-add-product-keywords' can be used to add
+ font-lock rules to the product specific rules. For example, to have
+ all identifiers ending in "_t" under MS SQLServer treated as a type,
+ you would use the following line in your .emacs file:
+
+ (sql-add-product-keywords 'ms
+ '("\\<\\w+_t\\>" . font-lock-type-face))
+
+ *** Oracle support includes keyword highlighting for Oracle 9i. Most
+ SQL and PL/SQL keywords are implemented. SQL*Plus commands are
+ highlighted in `font-lock-doc-face'.
+
+ *** Microsoft SQLServer support has been significantly improved.
+ Keyword highlighting for SqlServer 2000 is implemented.
+ sql-interactive-mode defaults to use osql, rather than isql, because
+ osql flushes it's error stream more frequently. Thus error messages
+ are displayed when they occur rather than when the session is
+ terminated.
+
+ If the username and password are not provided to `sql-ms', osql is
+ called with the -E command line argument to use the operating system
+ credentials to authenticate the user.
+
+ *** Imenu support has been enhanced to locate tables, views, indexes,
+ packages, procedures, functions, triggers, sequences, rules, and
+ defaults.
+
+ *** Added SQL->Start SQLi Session menu entry which calls the
+ appropriate sql-interactive-mode wrapper for the current setting of
+ `sql-product'.
+
+ ** M-x view-file and commands that use it now avoid interfering
+ with special modes such as Tar mode.
+
+ ** Enhancements to apropos commands:
+
+ *** The apropos commands will now accept a list of words to match.
+ When more than one word is specified, at least two of those words must
+ be present for an item to match. Regular expression matching is still
+ available.
+
+ *** The new option `apropos-sort-by-scores' causes the matching items
+ to be sorted according to their score. The score for an item is a
+ number calculated to indicate how well the item matches the words or
+ regular expression that you entered to the apropos command. The best
+ match is listed first, and the calculated score is shown for each
+ matching item.
+
+ +++
+ ** The old bindings C-M-delete and C-M-backspace have been deleted,
+ since there are situations where one or the other will shut down
+ the operating system or your X server.
+
+ ** New minor mode, Visible mode, toggles invisibility in the current buffer.
+ When enabled, it makes all invisible text visible. When disabled, it
+ restores the previous value of `buffer-invisibility-spec'.
+
+ ** New command `kill-whole-line' kills an entire line at once.
+ By default, it is bound to C-S-<backspace>.
+
+ +++
+ ** Info now hides node names in menus and cross references by default.
+ If you prefer the old behavior, you can set the new user option
+ `Info-hide-note-references' to nil.
+
+ ** Support for the SQLite interpreter has been added to sql.el by calling
+ 'sql-sqlite'.
+
+ ** BibTeX mode:
+ *** New `bibtex-entry-format' option `required-fields', enabled by default.
+ *** bibtex-maintain-sorted-entries can take values `plain',
+ `crossref', and `entry-class' which control the sorting scheme used
+ for BibTeX entries. `bibtex-sort-entry-class' controls the sorting
+ scheme `entry-class'. TAB completion for reference keys and
+ automatic detection of duplicates does not require anymore that
+ bibtex-maintain-sorted-entries is non-nil.
+
+ *** If the new variable bibtex-parse-keys-fast is non-nil,
+ use fast but simplified algorithm for parsing BibTeX keys.
+
+ *** If the new variable bibtex-autoadd-commas is non-nil,
+ automatically add missing commas at end of BibTeX fields.
+
+ *** The new variable bibtex-autofill-types contains a list of entry
+ types for which fields are filled automatically (if possible).
+
+ *** The new command bibtex-complete completes word fragment before
+ point according to context (bound to M-tab).
+
+ *** The new commands bibtex-find-entry and bibtex-find-crossref
+ locate entries and crossref'd entries.
+
+ *** In BibTeX mode the command fill-paragraph (bound to M-q) fills
+ individual fields of a BibTeX entry.
+
+ ** When display margins are present in a window, the fringes are now
+ displayed between the margins and the buffer's text area, rather than
+ at the edges of the window.
+
+ ** A window may now have individual fringe and scroll-bar settings,
+ in addition to the individual display margin settings.
+
+ Such individual settings are now preserved when windows are split
+ horizontally or vertically, a saved window configuration is restored,
+ or when the frame is resized.
+
+ ** New functions frame-current-scroll-bars and window-current-scroll-bars.
+
+ These functions return the current locations of the vertical and
+ horisontal scroll bars in a frame or window.
+
+ ** Under X, mouse-wheel-mode is turned on by default.
+
+ ** The X resource useXIM can be used to turn off use of XIM, which may
+ speed up Emacs with slow networking to the X server.
+
+ If the configure option `--without-xim' was used to turn off use of
+ XIM by default, the X resource useXIM can be used to turn it on.
+
+ ** `describe-char' can show data from the Unicode database file. See
+ user option `unicode-data'.
+
+ ** `undo-only' does an undo which does not redo any previous undo.
+
+ ** `uniquify-strip-common-suffix' tells uniquify to prefer
+ `file|dir1' and `file|dir2' to `file|dir1/subdir' and `file|dir2/subdir'.
+
+ ** If the user visits a file larger than `large-file-warning-threshold',
+ Emacs will prompt her for confirmation.
+
+ ** A UTF-7 coding system is available in the library `utf-7'.
+
+ ** GUD mode has its own tool bar for controlling execution of the inferior
+ and other common debugger commands.
+
+ ** recentf changes.
+
+ The recent file list is now automatically cleanup when recentf mode is
+ enabled. The new option `recentf-auto-cleanup' controls when to do
+ automatic cleanup.
+
+ With the more advanced option: `recentf-filename-handler', you can
+ specify a function that transforms filenames handled by recentf. For
+ example, if set to `file-truename', the same file will not be in the
+ recent list with different symbolic links.
+
+ To follow naming convention, `recentf-keep-non-readable-files-flag'
+ and `recentf-menu-append-commands-flag' respectively replace the
+ misnamed options `recentf-keep-non-readable-files-p' and
+ `recentf-menu-append-commands-p'. The old names remain available as
+ aliases, but have been marked obsolete.
+
** The default for the paper size (variable ps-paper-type) is taken
from the locale.

+++
+ ** CC Mode changes.
+
+ *** Font lock support.
+ CC Mode now provides font lock support for all its languages. This
+ supersedes the font lock patterns that have been in the core font lock
+ package for C, C++, Java and Objective-C. Like indentation, font
+ locking is done in a uniform way across all languages (except the new
+ AWK mode - see below). That means that the new font locking will be
+ different from the old patterns in various details for most languages.
+
+ The main goal of the font locking in CC Mode is accuracy, to provide a
+ dependable aid in recognizing the various constructs. Some, like
+ strings and comments, are easy to recognize while others like
+ declarations and types can be very tricky. CC Mode can go to great
+ lengths to recognize declarations and casts correctly, especially when
+ the types aren't recognized by standard patterns. This is a fairly
+ demanding analysis which can be slow on older hardware, and it can
+ therefore be disabled by choosing a lower decoration level with the
+ variable font-lock-maximum-decoration.
+
+ Note that the most demanding font lock level has been tuned with lazy
+ fontification in mind, i.e. there should be a support mode that waits
+ with the fontification until the text is actually shown
+ (e.g. Just-in-time Lock mode, which is the default, or Lazy Lock
+ mode). Fontifying a file with several thousand lines in one go can
+ take the better part of a minute.
+
+ **** The (c|c++|objc|java|idl|pike)-font-lock-extra-types variables
+ are now used by CC Mode to recognize identifiers that are certain to
+ be types. (They are also used in cases that aren't related to font
+ locking.) At the maximum decoration level, types are often recognized
+ properly anyway, so these variables should be fairly restrictive and
+ not contain patterns for uncertain types.
+
+ **** Support for documentation comments.
+ There is a "plugin" system to fontify documentation comments like
+ Javadoc and the markup within them. It's independent of the host
+ language, so it's possible to e.g. turn on Javadoc font locking in C
+ buffers. See the variable c-doc-comment-style for details.
+
+ Currently two kinds of doc comment styles are recognized: Suns Javadoc
+ and Autodoc which is used in Pike. This is by no means a complete
+ list of the most common tools; if your doc comment extractor of choice
+ is missing then please drop a note to address@hidden
+
+ **** Better handling of C++ templates.
+ As a side effect of the more accurate font locking, C++ templates are
+ now handled much better. The angle brackets that delimit them are
+ given parenthesis syntax so that they can be navigated like other
+ parens.
+
+ This also improves indentation of templates, although there still is
+ work to be done in that area. E.g. it's required that multiline
+ template clauses are written in full and then refontified to be
+ recognized, and the indentation of nested templates is a bit odd and
+ not as configurable as it ought to be.
+
+ **** Improved handling of Objective-C and CORBA IDL.
+ Especially the support for Objective-C and IDL has gotten an overhaul.
+ The special "@" declarations in Objective-C are handled correctly.
+ All the keywords used in CORBA IDL, PSDL, and CIDL are recognized and
+ handled correctly, also wrt indentation.
+
+ *** Support for the AWK language.
+ Support for the AWK language has been introduced. The implementation is
+ based around GNU AWK version 3.1, but it should work pretty well with
+ any AWK. As yet, not all features of CC Mode have been adapted for AWK.
+ Here is a summary:
+
+ **** Indentation Engine
+ The CC Mode indentation engine fully supports AWK mode.
+
+ AWK mode handles code formatted in the conventional AWK fashion: `{'s
+ which start actions, user-defined functions, or compound statements are
+ placed on the same line as the associated construct; the matching `}'s
+ are normally placed under the start of the respective pattern, function
+ definition, or structured statement.
+
+ The predefined indentation functions haven't yet been adapted for AWK
+ mode, though some of them may work serendipitously. There shouldn't be
+ any problems writing custom indentation functions for AWK mode.
+
+ The command C-c C-q (c-indent-defun) hasn't yet been adapted for AWK,
+ though in practice it works properly nearly all the time. Should it
+ fail, explicitly set the region around the function (using C-u C-SPC:
+ C-M-h probably won't work either) then do C-M-\ (indent-region).
+
+ **** Font Locking
+ There is a single level of font locking in AWK mode, rather than the
+ three distinct levels the other modes have. There are several
+ idiosyncrasies in AWK mode's font-locking due to the peculiarities of
+ the AWK language itself.
+
+ **** Comment Commands
+ M-; (indent-for-comment) works fine. None of the other CC Mode
+ comment formatting commands have yet been adapted for AWK mode.
+
+ **** Movement Commands
+ Most of the movement commands work in AWK mode. The most important
+ exceptions are M-a (c-beginning-of-statement) and M-e
+ (c-end-of-statement) which haven't yet been adapted.
+
+ The notion of "defun" has been augmented to include AWK pattern-action
+ pairs. C-M-a (c-awk-beginning-of-defun) and C-M-e (c-awk-end-of-defun)
+ recognise these pattern-action pairs, as well as user defined
+ functions.
+
+ **** Auto-newline Insertion and Clean-ups
+ Auto-newline insertion hasn't yet been adapted for AWK. Some of
+ the clean-ups can actually convert good AWK code into syntactically
+ invalid code. These features are best disabled in AWK buffers.
+
+ *** New syntactic symbols in IDL mode.
+ The top level constructs "module" and "composition" (from CIDL) are
+ now handled like "namespace" in C++: They are given syntactic symbols
+ module-open, module-close, inmodule, composition-open,
+ composition-close, and incomposition.
+
+ *** New functions to do hungry delete without enabling hungry delete mode.
+ The functions c-hungry-backspace and c-hungry-delete-forward can be
+ bound to keys to get this feature without toggling a mode.
+ Contributed by Kevin Ryde.
+
+ *** Better control over require-final-newline.
+ The variable that controls how to handle a final newline when the
+ buffer is saved, require-final-newline, is now customizable on a
+ per-mode basis through c-require-final-newline. The default is to set
+ it to t only in languages that mandate a final newline in source files
+ (C, C++ and Objective-C).
+
+ *** Format change for syntactic context elements.
+ The elements in the syntactic context returned by c-guess-basic-syntax
+ and stored in c-syntactic-context has been changed somewhat to allow
+ attaching more information. They are now lists instead of single cons
+ cells. E.g. a line that previously had the syntactic analysis
+
+ ((inclass . 11) (topmost-intro . 13))
+
+ is now analysed as
+
+ ((inclass 11) (topmost-intro 13))
+
+ In some cases there are more than one position given for a syntactic
+ symbol.
+
+ This change might affect code that call c-guess-basic-syntax directly,
+ and custom lineup functions if they use c-syntactic-context. However,
+ the argument given to lineup functions is still a single cons cell
+ with nil or an integer in the cdr.
+
+ *** API changes for derived modes.
+ There have been extensive changes "under the hood" which can affect
+ derived mode writers. Some of these changes are likely to cause
+ incompatibilities with existing derived modes, but on the other hand
+ care has now been taken to make it possible to extend and modify CC
+ Mode with less risk of such problems in the future.
+
+ **** New language variable system.
+ See the comment blurb near the top of cc-langs.el.
+
+ **** New initialization functions.
+ The initialization procedure has been split up into more functions to
+ give better control: c-basic-common-init, c-font-lock-init, and
+ c-init-language-vars.
+
+ *** Changes in analysis of nested syntactic constructs.
+ The syntactic analysis engine has better handling of cases where
+ several syntactic constructs appear nested on the same line. They are
+ now handled as if each construct started on a line of its own.
+
+ This means that CC Mode now indents some cases differently, and
+ although it's more consistent there might be cases where the old way
+ gave results that's more to one's liking. So if you find a situation
+ where you think that the indentation has become worse, please report
+ it to address@hidden
+
+ **** New syntactic symbol substatement-label.
+ This symbol is used when a label is inserted between a statement and
+ its substatement. E.g:
+
+ if (x)
+ x_is_true:
+ do_stuff();
+
+ *** Better handling of multiline macros.
+
+ **** Syntactic indentation inside macros.
+ The contents of multiline #define's are now analyzed and indented
+ syntactically just like other code. This can be disabled by the new
+ variable c-syntactic-indentation-in-macros. A new syntactic symbol
+ cpp-define-intro has been added to control the initial indentation
+ inside #define's.
+
+ **** New lineup function c-lineup-cpp-define.
+ Now used by default to line up macro continuation lines. The behavior
+ of this function closely mimics the indentation one gets if the macro
+ is indented while the line continuation backslashes are temporarily
+ removed. If syntactic indentation in macros is turned off, it works
+ much line c-lineup-dont-change, which was used earlier, but handles
+ empty lines within the macro better.
+
+ **** Automatically inserted newlines continues the macro if used within one.
+ This applies to the newlines inserted by the auto-newline mode, and to
+ c-context-line-break and c-context-open-line.
+
+ **** Better alignment of line continuation backslashes.
+ c-backslash-region tries to adapt to surrounding backslashes. New
+ variable c-backslash-max-column which put a limit on how far out
+ backslashes can be moved.
+
+ **** Automatic alignment of line continuation backslashes.
+ This is controlled by the new variable c-auto-align-backslashes. It
+ affects c-context-line-break, c-context-open-line and newlines
+ inserted in auto-newline mode.
+
+ **** Line indentation works better inside macros.
+ Regardless whether syntactic indentation and syntactic indentation
+ inside macros are enabled or not, line indentation now ignores the
+ line continuation backslashes. This is most noticeable when syntactic
+ indentation is turned off and there are empty lines (save for the
+ backslash) in the macro.
+
+ *** indent-for-comment is more customizable.
+ The behavior of M-; (indent-for-comment) is now configurable through
+ the variable c-indent-comment-alist. The indentation behavior based
+ on the preceding code on the line, e.g. to get two spaces after #else
+ and #endif but indentation to comment-column in most other cases
+ (something which was hardcoded earlier).
+
+ *** New function c-context-open-line.
+ It's the open-line equivalent of c-context-line-break.
+
+ *** New lineup functions
+
+ **** c-lineup-string-cont
+ This lineup function lines up a continued string under the one it
+ continues. E.g:
+
+ result = prefix + "A message "
+ "string."; <- c-lineup-string-cont
+
+ **** c-lineup-cascaded-calls
+ Lines up series of calls separated by "->" or ".".
+
+ **** c-lineup-knr-region-comment
+ Gives (what most people think is) better indentation of comments in
+ the "K&R region" between the function header and its body.
+
+ **** c-lineup-gcc-asm-reg
+ Provides better indentation inside asm blocks. Contributed by Kevin
+ Ryde.
+
+ **** c-lineup-argcont
+ Lines up continued function arguments after the preceding comma.
+ Contributed by Kevin Ryde.
+
+ *** Better caching of the syntactic context.
+ CC Mode caches the positions of the opening parentheses (of any kind)
+ of the lists surrounding the point. Those positions are used in many
+ places as anchor points for various searches. The cache is now
+ improved so that it can be reused to a large extent when the point is
+ moved. The less it moves, the less needs to be recalculated.
+
+ The effect is that CC Mode should be fast most of the time even when
+ opening parens are hung (i.e. aren't in column zero). It's typically
+ only the first time after the point is moved far down in a complex
+ file that it'll take noticeable time to find out the syntactic
+ context.
+
+ *** Statements are recognized in a more robust way.
+ Statements are recognized most of the time even when they occur in an
+ "invalid" context, e.g. in a function argument. In practice that can
+ happen when macros are involved.
+
+ *** Improved the way c-indent-exp chooses the block to indent.
+ It now indents the block for the closest sexp following the point
+ whose closing paren ends on a different line. This means that the
+ point doesn't have to be immediately before the block to indent.
+ Also, only the block and the closing line is indented; the current
+ line is left untouched.
+
+ *** Added toggle for syntactic indentation.
+ The function c-toggle-syntactic-indentation can be used to toggle
+ syntactic indentation.
+
** The command line option --no-windows has been changed to

+ and `unify-8859-on-decoding-mode' respectively turn on translation
+ between ISO 8859 character sets (`unification') on encoding
+ (e.g. writing a file) and decoding (e.g. reading a file). Note that
+ `unify-8859-on-encoding-mode' is useful and safe, but
+ `unify-8859-on-decoding-mode' can cause text to change when you read
+ it and write it out again without edits, so it is not generally advisable.
+ By default `unify-8859-on-encoding-mode' is turned on.
+
+ ** In Emacs running on the X window system, the default value of
+ `selection-coding-system' is now `compound-text-with-extensions'.
+
+ If you want the old behavior, set selection-coding-system to
+ compound-text, which may be significantly more efficient. Using
+ compound-text-with-extensions seems to be necessary only for decoding
+ text from applications under XFree86 4.2, whose behaviour is actually
+ contrary to the compound text specification.
+
+
+ * Installation changes in Emacs 21.2
+
+ ** Support for BSD/OS 5.0 has been added.
+
+ ** Support for AIX 5.1 was added.
+
+
+ * Changes in Emacs 21.2
+
+ ** Emacs now supports compound-text extended segments in X selections.
+
+ X applications can use `extended segments' to encode characters in
+ compound text that belong to character sets which are not part of the
+ list of approved standard encodings for X, e.g. Big5. To paste
+ selections with such characters into Emacs, use the new coding system
+ compound-text-with-extensions as the value of selection-coding-system.
+
+ ** The default values of `tooltip-delay' and `tooltip-hide-delay'
+ were changed.
+
+ ** On terminals whose erase-char is ^H (Backspace), Emacs
+ now uses normal-erase-is-backspace-mode.
+
+ ** When the *scratch* buffer is recreated, its mode is set from
+ initial-major-mode, which normally is lisp-interaction-mode,
+ instead of using default-major-mode.
+
+ ** The new option `Info-scroll-prefer-subnodes' causes Info to behave
+ like the stand-alone Info reader (from the GNU Texinfo package) as far
+ as motion between nodes and their subnodes is concerned. If it is t
+ (the default), Emacs behaves as before when you type SPC in a menu: it
+ visits the subnode pointed to by the first menu entry. If this option
+ is nil, SPC scrolls to the end of the current node, and only then goes
+ to the first menu item, like the stand-alone reader does.
+
+ This change was already in Emacs 21.1, but wasn't advertised in the
+ NEWS.
+
+
+ * Lisp Changes in Emacs 21.2
+
+ ** The meanings of scroll-up-aggressively and scroll-down-aggressively
+ have been interchanged, so that the former now controls scrolling up,
+ and the latter now controls scrolling down.
+
+ ** The variable `compilation-parse-errors-filename-function' can
+ be used to transform filenames found in compilation output.
+
+
