*** Special markup can be added to log-edit buffers.
variables `sql-product', `sql-user', `sql-server', `sql-database' and
`sql-port' can now be safely used as local variables.
-*** Added ability to login with a port on MySQL.
+*** `sql-dialect' is a synonym for `sql-product'.
+
+*** Added ability to login with a port on MySQL and Postgres.
The custom variable `sql-port' can be specified for connection to
-MySQL servers.
+MySQL or Postgres servers. By default, the port is not listed in
+either login parameter, but will be added to the command line if set
+to a non-zero value.
+
+*** Dynamic selection of product in an SQL interactive session.
+If you use `sql-product-interactive' to start an SQL interactive
+session it uses the current value of `sql-product'. Preceding the
+invocation with C-u will force it to ask for the product before
+creating the session.
+
+*** Renaming a SQL interactive buffer when it is created.
+Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres',
+`sql-mysql', etc.) with C-u will force a new interactive session to be
+started and will prompt for the new name. This will reduce the need
+for `sql-rename-buffer' is most common use cases.
*** Command continuation prompts in SQL interactive mode are suppressed.
Multiple line commands in SQL interactive mode, generate command
which is a list of the parameters to be prompted for before a
connection is established.
-By default, the value of the parameter is simply prompted for. For
-`server' and `database', they can be specified in a list as shown
-below:
-
- (server :file ARG)
- (database :file ARG)
- (server :completion ARG)
- (database :completion ARG)
-
-The ARG when :file is specified is a regexp that will match valid file
-names (without the directory portion). Generally these strings will
-be of the form ".+\.SUF" where SUF is the desired file suffix.
-
-When :completion is specified, the ARG corresponds to the PREDICATE
-argument to the `completing-read' function (a list of possible values
-or a function returning such a list).
+The lists consist of the following five tokens: `user', `password',
+`database', `server', and `port'. The order in which they appear is
+the order in which they are prompted. The tokens symbols can be
+replaced by a sublist starting with the token and followed by a plist
+which control the prompting for values. The tokens `user',
+`database', and `server' each can take a property of :default which
+specifies the value to be used if no value is entered. The
+`database', `server', and `port' tokens handle the :completion
+property which restricts the entry to either one of the values in the
+list or to one of the values returned by the function provided as the
+property value. The `database' and `server' tokens also accept the
+:file property whose value is a regexp to identify useful file names.
+
+ (user :default DEF)
+ (database :default DEF
+ :file FILEPAT
+ :completion COMPLETE)
+ (server :default DEF
+ :file FILEPAT
+ :completion COMPLETE)
+
+The FILEPAT when :file is specified is a regexp that will match valid
+file names (without the directory portion). Generally these strings
+will be of the form ".+\.SUF" where SUF is the desired file suffix.
+
+When :completion is specified, the COMPLETE corresponds to the
+PREDICATE argument to the `completing-read' function (a list of
+possible values or a function returning such a list).
*** Added `sql-connection-alist' to record login parameter values.
An alist for recording different username, database and server
for the users password and then connect to the Oracle database.
**** Added SQL->Start... submenu when connections are defined.

+When connections have been defined, there is a submenu available that
allows the user to select one to start a SQLi session. The "Start
SQLi Session" item moves to the "Start..." submenu when cnnections
have been defined.
`sql-save-connection' will gather the login params specified for the
session and save them as a new connection.
+*** List database objects and details.
+Once a SQL interactive session has been started, you can get a list of
+the objects in the database and see details of those objects. The
+objects shown and the details available are product specific.
+
+**** List all objects.
+Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
+objects" will list all the objects in the database. At a minimum it
+lists the tables and views in the database. Preceeding the command by
+universal argument may provide additional details or extend the
+listing to include other schemas objects. The list will appear in a
+separate window in view-mode.
+
+**** List Table details.
+Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
+details" will ask for the name of a database table or view and display
+the list of columns in the relation. Preceeding the comand with the
+universal argument may provide additional details about each column.
+The list will appear in a separate window in view-mode.
+
*** Added option `sql-send-terminator'.
When set makes sure that each command sent with `sql-send-*' commands
are properly terminated and submitted to the SQL processor.

* Lisp changes in Emacs 24.1
+** New variable syntax-propertize-function to set syntax-table properties.
+Replaces font-lock-syntactic-keywords which are now obsolete.
+This allows syntax-table properties to be set independently from font-lock:
+just call syntax-propertize to make sure the text is propertized.
+Together with this new variable come a new hook
+syntax-propertize-extend-region-functions, as well as two helper functions:
+syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
+as-is; and syntax-propertize-rules which provides a new way to specify
+syntactic rules.
+
+** New hook post-self-insert-hook run at the end of self-insert-command.
+
++++
** Syntax tables support a new "comment style c" additionally to style b.
** frame-local variables cannot be let-bound any more.
** prog-mode is a new major-mode meant to be the parent of programming mode.
** define-minor-mode accepts a new keyword :variable.
-** `delete-file' and `delete-directory now accept optional arg TRASH.
+** `delete-file' and `delete-directory' now accept optional arg TRASH.
Trashing is performed if TRASH and `delete-by-moving-to-trash' are
both non-nil. Interactively, TRASH defaults to t, unless a prefix
argument is supplied (see Trash changes, above).
*** `image-extension-data' is renamed to `image-metadata'.
+** XML and HTML parsing
+
+*** If Emacs is compiled with libxml2 support (which is the default),
+two new Emacs Lisp-level functions are defined:
+`xml-parse-html-string-internal' (which will parse "real world" HTML)
+and `xml-parse-string-internal' (which parses XML). Both return an
+Emacs Lisp parse tree.
+
+FIXME: These should be front-ended by xml.el.
