[Amin Bandali]

branch: emacs-28
commit 30b5e0a51417490e577407b7b0cc80983890e7be
Author: Amin Bandali <bandali@gnu.org>
Commit: Amin Bandali <bandali@gnu.org>

    Add NEWS items for changes to ERC since 5.3 to etc/ERC-NEWS
    
    * etc/ERC-NEWS: copy ERC NEWS items from etc/NEWS, etc/NEWS.27,
    etc/NEWS.26, etc/NEWS.25, and etc/NEWS.24 to here.  Future ERC NEWS
    are also to be added here.  This is in motivated by preparation for
    addition of ERC to GNU ELPA, along with the ERC manual and NEWS.
    * etc/NEWS: remove ERC-related entries, and refer the reader to
    ERC-NEWS instead.

-* For changes after ERC 5.3, see the main Emacs NEWS file
+* Changes in ERC 5.4
+
+** Starting with Emacs 28.1 and ERC 5.4, ERC NEWS are added here again.
+After ERC 5.3, since November 2012, ERC's NEWS items were added in the
+main Emacs NEWS file, and users were referred to there.  Now, starting
+with Emacs 28.1 and ERC 5.4, which mark ERC's release to GNU ELPA, ERC
+NEWS have been moved to this file again, so that we can include a NEWS
+file consisting only of ERC changes in ERC's package on GNU ELPA.
+
+The NEWS entries for ERC changes in Emacs 28.1 have been moved from
+the main Emacs NEWS file to here.  For ERC NEWS entries corresponding
+to Emacs versions before 28, to avoid modifying the NEWS file for all
+of those releases, the ERC NEWS entries have only been copied below,
+and the NEWS.* files were left intact.
+
+*** New option 'erc-rename-buffers'.
+
+*** New faces 'erc-my-nick-prefix-face' and 'erc-nick-prefix-face'.
+
+*** 'erc-format-@nick' displays all user modes instead of only op and voice.
+
+*** The display of irc commands in the current buffer has been disabled.
+
+*** 'erc-version' now follows the Emacs version.
+
+*** ERC can now hide message types by network or channel.
+'erc-hide-list' will hide all messages of the specified type, while
+'erc-network-hide-list' and 'erc-channel-hide-list' will only hide the
+specified message types for the respective specified targets.
+
+*** Reconnection is now asynchronous.
+
+*** Nick completion is now case-insensitive again after inadvertently
+being made case-sensitive in Emacs 24.2.
+
+*** New variable 'erc-default-port-tls' used to connect to TLS IRC
+servers.
+
+*** New hook 'erc-insert-done-hook'.
+This hook is called after strings have been inserted into the buffer,
+and is free to alter point and window configurations, as it's not
+called from inside a 'save-excursion', as opposed to 'erc-insert-post-hook'.
+
+*** 'erc-button-google-url' has been renamed to 'erc-button-search-url'
+and its value has been changed to Duck Duck Go.
+
+*** 'erc-send-pre-hook' and 'erc-send-this' have been obsoleted.
+The user option to use instead to alter text to be sent is now
+'erc-pre-send-functions'.
+
+*** Improve matching/highlighting of nicknames.
+Open and close parenthesis and apostrophe are not considered valid
+nick characters anymore, matching the given grammar in RFC 2812
+section 2.3.1.  This enables correct matching and highlighting of
+nicks when they are surrounded by parentheses, like "(nick)", and when
+adjacent to an apostrophe, like "nick's".
+
+*** Set 'erc-button-url-regexp' to 'browse-url-button-regexp'
+which better handles surrounding pair of parentheses.
+
+*** New function 'erc-switch-to-buffer-other-window'
+which is like 'erc-switch-to-buffer', but opens the buffer in another
+window.
+
+*** New function 'erc-track-switch-buffer-other-window'
+which is like 'erc-track-switch-buffer', but opens the buffer in
+another window.
+
+*** NickServ passwords can now be retrieved from auth-source.
+The 'erc-use-auth-source-for-nickserv-password' user option enables
+querying auth-source for NickServ passwords.  To enable this, add the
+following to your init file:
+
+    (setq erc-use-auth-source-for-nickserv-password t)
+
+*** NickServ identification now prompts for password last.
+When 'erc-prompt-for-nickserv-password' is non-nil, the user used to
+be unconditionally prompted interactively for a password, regardless
+of the value of 'erc-nickserv-passwords', which was effectively
+ignored (same for the new
+'erc-use-auth-source-for-nickserv-password').  This limitation is now
+lifted, and the user is interactively prompted last, after the other
+identification methods have run.
+
+*** The '/ignore' command will now ask for a timeout to stop ignoring the user.
+Allowed inputs are seconds or ISO8601-like periods like "1h" or "4h30m".
+
+*** ERC now recognizes 'C-]' for italic text.
+Italic text is displayed in the new 'erc-italic-face'.
+
+*** erc-match.el now supports 'message' highlight type (not including the 
nick).
+The 'erc-current-nick-highlight-type', 'erc-pal-highlight-type',
+'erc-fool-highlight-type', 'erc-keyword-highlight-type', and
+'erc-dangerous-host-highlight-type' user options now support a
+'message' type for highlighting the entire message but not the
+sender's nick.
+
+*** erc-status-sidebar.el is now part of ERC.
+The 'erc-status-sidebar' package which provides a HexChat-like
+activity overview sidebar for joined IRC channels is now part of ERC.
+
+*** erc-tls now supports specifying a TLS client certificate.
+The 'erc-tls' function has been updated to allow specifying a TLS
+client certificate for authentication, as an alternative to NickServ
+password-based authentication.  This is referred to as "CertFP" (short
+for Certificate Fingerprint) by several IRC networks.  See the Info
+node "(erc) Connecting" in the ERC manual for more details and
+examples on how to specify and use TLS client certificates with
+'erc-tls'.
+
+*** Update IRC-related references to point to Libera.Chat.
+The Free Software Foundation and the GNU Project have moved their
+official IRC channels from the Freenode network to Libera.Chat.
+For the original announcement and the follow-up update, including
+more details, see:
+
+https://lists.gnu.org/archive/html/info-gnu/2021-06/msg00005.html
+https://lists.gnu.org/archive/html/info-gnu/2021-06/msg00007.html
+
+Given the relocation of GNU and FSF's official IRC channels, as well
+as #emacs and various other Emacs-themed channels (see the link below)
+to Libera.Chat, IRC-related references in the Emacs repository have
+now been updated to point to Libera.Chat.
+
+https://lists.gnu.org/archive/html/info-gnu-emacs/2021-06/msg00000.html
+
+*** Add 'erc-track-select-mode-line-face' (obsoletes 'erc-track-find-face').
+The 'erc-track-find-face' function of the erc-track module has been
+declared obsolete and rewritten as 'erc-track-select-mode-line-face',
+with different expected arguments (the current and old faces are now
+separated) and clearer documentation.
+
+*** Add '/opme' and '/deopme' convenience commands.
+The new '/opme' convenience command asks ChanServ to set the operator
+status for the current nick in the current channel, and '/deopme'
+unsets it.
+
+*** Add '/wii' convenience command for whois with idle time.
+The new '/wii' convenience command calls the '/whois' command with the
+given nick as both arguments, which is useful for displaying the whois
+information for the nick along with idle time, even if the nick is on
+a different server than the one the current user is connected to.
+Using the given nick itself instead of the server it is connected to
+is not standardized, but is widely supported across IRC networks.
