This file is about changes in ERC, the powerful, modular, and
extensible IRC (Internet Relay Chat) client distributed with
GNU Emacs since Emacs version 22.1.


* Changes in ERC 5.7

** Changes in the library API.

*** Module setup runs in query buffers on reconnect.
A module's setup would always run in channel buffers on reconnect, due
to channels being rejoined, but query buffers lacked a similar
opportunity to reinitialize their state for the new session.  This is no
longer the case.

*** Local modules activate in preferred order instead of in reverse.
In recent versions, ERC has enabled local modules in the reverse order
of that produced by the "set" function used by 'setopt' and the Custom
UI for the option 'erc-modules'.  Specifically, Built-in locals were
activated in reverse lexicographic order after third-party ones, which
were simply reversed as given.  Now, just like with global modules, ERC
preserves the preferred order when activating local modules for new
sessions.


* Changes in ERC 5.6.2

** Option 'erc-log-insert-log-on-open' can be a function.
Rather than insert redundant logs into all buffers when reconnecting,
which is what happens when this option is set to t, ERC 5.6.2 allows
users to exercise more control by specifying a predicate.  The provided
'erc-log-new-target-buffer-p' tells ERC to only insert logs when
creating a new target buffer, such as when issuing a "/JOIN" or a
"/QUERY" or when connecting for the first time with autojoin configured.

** Changes in the library API.

*** Function 'erc-log-setup-logging' deprecated.
In order to ensure proper buffer-local setup, the 'log' module has
always run this function somewhat indiscriminately and overly often.
This might be fine were it not for the function's interest in the option
'erc-log-insert-log-on-open' and its consequent altering of buffer text
in a manner only conducive to buffer creation.  The module now conducts
such business in a tidier and more internal fashion that no longer has
any use for the function nor its presence in 'erc-connect-pre-hook'.

*** Accessors like 'erc-channel-user-voice' may ignore assignments.
ERC now silently ignores attempts to enable certain status flags on
'erc-channel-user' objects if the connection's "PREFIX" parameter omits
them.  In the future, ERC will likely signal an error if such an attempt
is made.  Users can preview this potentially disruptive behavior by
setting the new variable 'erc-channel-user-signal-if-status-unknown' to
t.  This change stems from a bug fix for a regression affecting ERC 5.6
and 5.6.1 in which these accessors mishandled unsupported flags.


* Changes in ERC 5.6.1

** Option 'erc-truncate-padding-size' controls truncation frequency.
In fast-moving channels and in queries with long-winded bots, the
'truncate' module has historically been asked to work overtime, mostly
on account of a rather stingy buffering threshold of 512 characters.
Now configurable, its default has been relaxed eightfold to 4096.

** Option 'erc-modules' no longer autoloaded.
This cornerstone of ERC's configuration system was autoloaded globally
in 5.6 to allow users the freedom of running 'customize-option' without
first having to load the package.  Unfortunately, this also had the side
effect of arranging for ERC to load on startup whenever someone
customized the variable.

** New option determines 'keep-place-indicator's influence on 'truncate'.
Option 'erc-keep-place-indicator-truncation' manages the tension between
truncation and place keeping, prioritizing one or the other.

** Stray key binding removed from 'erc-fill-wrap-mode-map'.
The command 'erc-fill-wrap-cycle-visual-movement' was mistakenly given
the key binding "C-c a" in an inadvertent holdover from development.  It
