* Installation changes

** Upgrading from previous (stable) version if you have used No Gnus.

If you have tried No Gnus (the unstable Gnus branch leading to this
release) but went back to a stable version, be careful when upgrading to
this version.  In particular, you will probably want to remove the
`~/News/marks' directory (perhaps selectively), so that flags are read
from your `~/.newsrc.eld' instead of from the stale marks file, where
this release will store flags for nntp.  See a later entry for more
information about nntp marks.  Note that downgrading isn't safe in
general.

** Lisp files are now installed in `.../site-lisp/gnus/' by default.  It
defaulted to `.../site-lisp/' formerly.  In addition to this, the new
installer issues a warning if other Gnus installations which will shadow
the latest one are detected.  You can then remove those shadows manually
or remove them using `make remove-installed-shadows'.

** New `make.bat' for compiling and installing Gnus under MS Windows

Use `make.bat' if you want to install Gnus under MS Windows, the first
argument to the batch-program should be the directory where `xemacs.exe'
respectively `emacs.exe' is located, if you want to install Gnus after
compiling it, give `make.bat' `/copy' as the second parameter.

`make.bat' has been rewritten from scratch, it now features automatic
recognition of XEmacs and GNU Emacs, generates `gnus-load.el', checks if
errors occur while compilation and generation of info files and reports
them at the end of the build process.  It now uses `makeinfo' if it is
available and falls back to `infohack.el' otherwise.  `make.bat' should
now install all files which are necessary to run Gnus and be generally a
complete replacement for the `configure; make; make install' cycle used
under Unix systems.

The new `make.bat' makes `make-x.bat' and `xemacs.mak' superfluous, so
they have been removed.

** `~/News/overview/' not used.

As a result of the following change, the `~/News/overview/' directory is
not used any more.  You can safely delete the entire hierarchy.

** `(require 'gnus-load)'

If you use a stand-alone Gnus distribution, you'd better add `(require
'gnus-load)' into your `~/.emacs' after adding the Gnus lisp directory
into load-path.

File `gnus-load.el' contains autoload commands, functions and variables,
some of which may not be included in distributions of Emacsen.


\f
* New packages and libraries within Gnus

** Gnus includes the Emacs Lisp SASL library.

This provides a clean API to SASL mechanisms from within Emacs.  The
user visible aspects of this, compared to the earlier situation, include
support for DIGEST-MD5 and NTLM.   *Note Emacs SASL: (sasl)Top.

** ManageSieve connections uses the SASL library by default.

The primary change this brings is support for DIGEST-MD5 and NTLM, when
the server supports it.

** Gnus includes a password cache mechanism in password.el.

It is enabled by default (see `password-cache'), with a short timeout of
16 seconds (see `password-cache-expiry').  If PGG is used as the PGP
back end, the PGP passphrase is managed by this mechanism.  Passwords
for ManageSieve connections are managed by this mechanism, after
querying the user about whether to do so.

\f
* Changes in summary and article mode

** International host names (IDNA) can now be decoded inside article bodies
using `W i' (`gnus-summary-idna-message').  This requires that GNU Libidn
(`http://www.gnu.org/software/libidn/') has been installed.

** Gnus now displays DNS master files sent as text/dns using dns-mode.

** Gnus supports new limiting commands in the Summary buffer: `/ r'
(`gnus-summary-limit-to-replied') and `/ R'
(`gnus-summary-limit-to-recipient').  *Note Limiting::.

** You can now fetch all ticked articles from the server using `Y t'
(`gnus-summary-insert-ticked-articles').  *Note Summary Generation
Commands::.

** Gnus supports a new sort command in the Summary buffer: `C-c C-s C-t'
(`gnus-summary-sort-by-recipient').  *Note Summary Sorting::.

** S/MIME now features LDAP user certificate searches.  You need to
configure the server in `smime-ldap-host-list'.

** URLs inside OpenPGP headers are retrieved and imported to your PGP key
ring when you click on them.

** Picons can be displayed right from the textual address, see
`gnus-picon-style'.  *Note Picons::.

** ANSI SGR control sequences can be transformed using `W A'.

ANSI sequences are used in some Chinese hierarchies for highlighting
articles (`gnus-article-treat-ansi-sequences').

** Gnus now MIME decodes articles even when they lack "MIME-Version" header.
This changes the default of `gnus-article-loose-mime'.

** `gnus-decay-scores' can be a regexp matching score files.  For example,
set it to `\\.ADAPT\\'' and only adaptive score files will be decayed.
 *Note Score Decays::.

** Strings prefixing to the `To' and `Newsgroup' headers in summary lines
when using `gnus-ignored-from-addresses' can be customized with
`gnus-summary-to-prefix' and `gnus-summary-newsgroup-prefix'.  *Note To
From Newsgroups::.

** You can replace MIME parts with external bodies.  See
`gnus-mime-replace-part' and `gnus-article-replace-part'.  *Note MIME
Commands::, *Note Using MIME::.

** The option `mm-fill-flowed' can be used to disable treatment of
format=flowed messages.  Also, flowed text is disabled when sending
inline PGP signed messages.  *Note Flowed text: (emacs-mime)Flowed text.
(New in Gnus 5.10.7)


\f
* Changes in Message mode

** Gnus now supports the "hashcash" client puzzle anti-spam mechanism.  Use
`(setq message-generate-hashcash t)' to enable.  *Note Hashcash::.

** You can now drag and drop attachments to the Message buffer.  See
`mml-dnd-protocol-alist' and `mml-dnd-attach-options'.  *Note MIME:
(message)MIME.

** The option `message-yank-empty-prefix' now controls how empty lines are
prefixed in cited text.  *Note Insertion Variables: (message)Insertion
Variables.

** Gnus uses narrowing to hide headers in Message buffers.  The
`References' header is hidden by default.  To make all headers visible,
use `(setq message-hidden-headers nil)'.  *Note Message Headers:
(message)Message Headers.

** You can highlight different levels of citations like in the article
buffer.  See `gnus-message-highlight-citation'.

** `auto-fill-mode' is enabled by default in Message mode.  See
`message-fill-column'.  *Note Message Headers: (message)Various Message
Variables.


\f
* Changes in back ends

** The nntp back end stores article marks in `~/News/marks'.

Earlier it was generated when the user configurable email address was
different from the Gnus guessed default user address.  As the guessing
algorithm is rarely correct these days, and (more controversially) the
only use of the Sender: header was to check if you are entitled to
cancel/supersede news (which is now solved by Cancel Locks instead, see
another entry), generation of the header has been disabled by default.
See the variables `message-required-headers',
`message-required-news-headers', and `message-required-mail-headers'.

** You can import and export your RSS subscriptions from OPML files.  *Note
RSS::.

** IMAP identity (RFC 2971) is supported.

By default, Gnus does not send any information about itself, but you can
customize it using the variable `nnimap-id'.

** The `nnrss' back end now supports multilingual text.  Non-ASCII group
names for the `nnrss' groups are also supported.  *Note RSS::.

** Retrieving mail with POP3 is supported over SSL/TLS and with StartTLS.

** The nnml back end allows other compression programs beside `gzip' for
compressed message files.  *Note Mail Spool::.

** The nnml back end supports group compaction.

This feature, accessible via the functions `gnus-group-compact-group'
(`G z' in the group buffer) and `gnus-server-compact-server' (`z' in the
server buffer) renumbers all articles in a group, starting from 1 and
removing gaps.  As a consequence, you get a correct total article count
(until messages are deleted again).

\f
* Appearance

** The tool bar has been updated to use GNOME icons.  You can also
customize the tool bar.  There's no documentation in the manual yet, but
`M-x customize-apropos RET -tool-bar$' should get you started.  (Only
for Emacs, not in XEmacs.)

** The tool bar icons are now (de)activated correctly in the group buffer,
see the variable `gnus-group-update-tool-bar'.  Its default value
depends on your Emacs version.

** You can change the location of XEmacs' toolbars in Gnus buffers.  See
`gnus-use-toolbar' and `message-use-toolbar'.


\f
* Miscellaneous changes

** Having edited the select-method for the foreign server in the server
buffer is immediately reflected to the subscription of the groups which
use the server in question.  For instance, if you change
`nntp-via-address' into `bar.example.com' from `foo.example.com', Gnus
will connect to the news host by way of the intermediate host
`bar.example.com' from next time.

** The `all.SCORE' file can be edited from the group buffer using `W e'.
