7.Extended /drawpic -o [N] to refer to frames in a GIF file.

19.Changed the way maximum server line lengths are applied to various
commands and features.
20.Added /privmsg command.
21.Added support for CPRIVMSG and CNOTICE. If listed in numeric 005,
PRIVMSG and NOTICE will be automatically upgraded for most
outgoing messages if you are an op/voice on a channel and message
a user on the same channel.
22.Added support for numeric 005 STATUSMSG=@+ and WALLVOICES and added
commands /vmsg, /vnotice, and /wallvoices. If server does not support
STATUSMSG, WALLCHOPS, or WALLVOICES, mIRC uses own method to send to
23.Changed line splitting method for long messages when:
1) Sending message through editbox of a channel/query window.
2) Using commands /ame /amsg /describe /me /msg /omsg /privmsg /qme
/qmsg /query /sound /vmsg /wallchops.
Note: when line splitting, the /sound command switches to an ACTION
message for the second line onwards.
Note: line splitting is not performed on NOTICEs, so is not applied
to /notice /onotice /vnotice /wallvoices.
24.Changed multiple target handling in PRIVMSG and NOTICE so that if
TARGMAX or MAXTARGETS are not specified in numeric 005, mIRC assumes
the maximum is one target per message.
25.Changed channel favorites dialog drag-resize method.
26.Changed channel mode parsing in numeric 324 and MODE events to handle
channel keys hidden from non-ops only on the Undernet ircd. As there
is no numeric 005 token for this, this is based on the Undernet ircd
version number in numeric 004.
Note: Added support for numeric 005 HIDDENKEY token. When specified,
this means that non-ops on a channel receive the * character as the
channel key in numeric 324 and MODE events. Clients should treat the
* character (or whatever character/string is sent) as a non-key if
they are not ops. If the user is then opped, their client can issue
a MODE to retrieve the real key.
27.Changed STATUSMSG support to use only NOTICE on the Undernet ircd,
which is the only method Undernet supports. On all other ircds,
STATUSMSG implies NOTICE/PRIVMSG. As there is no numeric 005 token
for this, this is based on the Undernet ircd version number in
28.Increased the size of short, medium, and long string lengths used
throughout mIRC that affect features such as variables, window names,
and so on.
29.Increased stack reserve size from 2 to 8 megabytes.
30.Added identifiers $maxlens $maxlenm $maxlenl that return the maximum
string lengths for small, medium, and large strings.
Note: although it is possible in some situations, eg. when assigning
values to variables, to store slightly longer strings, the values
returned by the above identifiers should be treated as maximums.
31.Changed CAP packet-size request to use mIRC's medium string length,
as returned by $maxlenm. The previous version was requesting 1024. If
a server replies with a different value, mIRC will use it, with a
mimumum of 512 and a maximum of $maxlenm.
32.Changed base64 implementation for $decode() to handle invalid input
33.Added $eventparms identifer that returns the event-specific parameters
passed to an executed command in a script.
34.Changed /ialfill to not issue a WHO if it thinks the IAL list is
already filled or currently filling.
35.Changed $base() to only remove the 0x prefix from base16 input.
36.Changed perform, and the joining of channels, on connect to trigger
only after a short delay, if the server connection uses nickserv to
identify a nickname. This ensures that you are able to join channels
that only allow identified users.
37.Fixed while loop parsing bug when $& is used to separate comparison
38.Changed when the raw event for invite (as a channel notification)
triggers to allow the /haltdef of default display text.
39.Fixed options/connect dialog new status window being opened with the
current status window's SSL port/state.
40.Updated OpenSSL library to v1.0.2p.
41.Added support for IRCv3 nested batches. This goes beyond the basic
batch support in previous versions and implements the full
specification, which includes nested batches and delaying batch
execution until end of batch is received. This includes support
for draft/label and draft/labeled-response.
42.Extended $hfind() 'w' and 'r' parameters to search entire length of
binary variable data. Note that in the case of 'r', long results
will be truncated due to internal string length limits.
43.Fixed $hash() parsing bug that caused a break evaluation error.
44.Changed how mIRC manages its string pool memory to ensure that very
large strings are freed immediately.
45.Changed $hfind() to allow $null text parameter.

47.Changed the way long lines are displayed to get around ExtTextOut()
48.Changed default hash table hash function to modified FNV-1A for
49.Added support for dynamic-resizing in hash tables for features like
the IAL, nickname lists, INI files, etc. that start off with small
hash tables and expand as necessary to improve performance.
50.Fixed $readini() reporting an evaluation error when reading a line
that contains only empty spaces.
51.Changed the [dirs] section to always contain "getdir", refers to
the default item in [extensions].

made to the way resources are loaded, the resources file has been

61.Changed /var to report an error if it is used outside a script.
62.Added /hload and /hsave -B switch that uses a larger index to allow
longer binary data to be saved. This is not compatible with files
created by the -b switch.
63.Changed script editor editbox to allow longer lines before it starts
64.Changed DCC Send file dialog to display some custom controls better
under dark mode in Windows 10.
