Early days
Miranda IM was first started by
Roland Rabien
(figbug) on February 2, 2000. At that time, it was a minimalist ICQ
clone and officially called Miranda ICQ. The first public release,
version 0.0.1, was released on February 6, 2000. This release used
LibICQ, had no support for message history, database, and
plugins, and had a distribution size of less than 100 KB.
A major new feature of version 0.0.4 was the
MegaHAL chat bot, which enabled automatic chatting between Miranda and other ICQ users. Plugin support was added with version 0.0.6.
Logger Plugin was the first plugin bundled with the official release.
Version 0.1.x
After the release of version 0.0.6.1 on December 26, 2000, the
original developers left, and Richard "cyreve" Hughes took over the
project. His first release, version 0.1.0.0 on April 8, 2001 was
improved through a major rewrite. The split message dialog bundled with
this release became the first messaging module to be put into a plugin.
The .Net Messenger Service protocol plugin appeared around the time of
version 0.1.1.0 release becoming the second messaging protocol to be
supported by Miranda. This was also the first official release to
support language pack translations. Miranda hence had multi-protocol,
multi-language instant messenger features.
After v0.1.0.0, Miranda plugin development grew rapidly. With version
0.1.2.1 (February 28, 2002), there were approximately 50 plugins
available. At the time the new
Lizard plugin enabled skinning support; the only time Miranda supported skins.
Lizard development stopped soon after, due to the instability it caused.
Version 0.2.x
After the mysterious disappearance of cyreve in June, 2002
the developers Martin Öberg (Strickz), Robert Rainwater (rainwater),
Sam K (egoDust), and Lyon Lim (lynlimz) took over the project. The MSN
protocol was taken over by Rako Shizuka who also developed the first
version of
Yahoo! Messenger protocol, which was the third protocol supported by Miranda. The
Yahoo!
plugin was closed source, and lost reliability as the official Yahoo!
Messenger protocol changed over time - it was later re-written by new
developer Gennady Feldman.
The first of the non-IM plugins, including
RSS News and
Weather,
were released within this period. These added a contact to contact list
for the purpose of displaying information to the user rather than
chatting.
Discussion about renaming of the program and removal of
ICQ from the core began about this time. Due to the increase of protocol support, the project was officially renamed to
Miranda IM on December 17, 2002.
The first release under the new name occurred on February 1, 2003,
about three years after the beginning of the project, and a bug fix
version came two weeks later.
Version 0.3.x
The major change in version 0.3, released on June 23, 2003, was the removal of
ICQ from the core into a plugin. From now on, Miranda could run without the
ICQ application being installed. The project moved to a new site at
www.miranda-im.org, featuring a new discussion board and file listing.
Protocol plugins bundled in version 0.3 included
ICQ,
MSN,
AIM, and
XMPP. The
Yahoo!
protocol was not included in the package. IRC support was added later
by Jörgen Persson (m8rix) to the official release of version 0.3.1, on
August 8, 2003.
Another major change was the removal of the
Send-Receive Messaging Module from the core into a plugin,
SRMM.
This reduced the size of the executable file and encouraged rapid
development of messaging modules. During this period many variations
(including
SRAMM,
SRMM_mod, etc.) offered different new features and improvements over the standard implementation.
ZDNet.be reviewed release 0.3, complimenting its "effortless" contact
importing, low memory usage, and extensive variety of plugins, and
stating, "Miranda is a strong recommendation for people who have a
system tray populated by several IM applications."
Version 0.4.x
Miranda IM, customized with plugins and skins.
Version 0.4 of Miranda IM was released on April 7, 2005. This was the first version to have
Yahoo!
protocol bundled with the official release. Other major changes
included the removal of contact list and database module from the core
into plugins.
As a result, there were 4 variations of contact list modules: the original
clist_classic, multi-window contact list
clist_mw, modern contact list
clist_modern, and nicer contact list with extensive UI customization
clist_nicer. Other popular plugins released within this period included tabbed message window (
tabsrmm and
scriver), HTML based message log support
IE view, scripting plugin
mbot, and the meta contact plugin.
Version 0.5.x
Version 0.5 of Miranda IM was released on July 28, 2006. This is the first version to have
Unicode support available as a download option for
Windows NT,
2000 and
XP users. Another new feature is the introduction of
AIM Oscar,
first released in early 2006, allowing users to transfer files and
receive away messages. This version also provided more support for
avatars among the various protocols.
Version 0.6.x
Customized Miranda IM 0.6.8 - plugins (Modern Contact List, SmileyAdd, Scriver...), skin (WIP Zune), icons, colors, etc...
Version 0.6 of Miranda IM was released on December 29, 2006. This version introduced
UPnP support to improve file transfer and direct connect reliability through
routers. Other changes included improved support for
UTF-8 strings, improved tabbed options support, and numerous bug fixes.
Version 0.7.x
Version 0.7 of Miranda IM was released on October 1, 2007. Key
changes included integrated font and icon services, a rewritten menu
engine, and a release notifier. One large change is a new way to
uniquely identify plugins and the interfaces they implement which may
break backward compatibility in the future.
A 2008
CNET
review gave the program 4 out of 5 stars, noting that though the
interface is "plain", the program supports most IM protocols in one
package. Features favored in the review included its centralized
personal information management, "numerous" window behavior controls,
and configurable hotkeys.
Techzine.nl
reviewed this version, listing its positive attributes as "support for
many protocols; small and fast; a lot of plug-ins and skins; many
settings" and writing it "will not look bad on your computer. Especially
if you are looking for a simple client on a USB stick then Miranda IM
is a good choice." On the other hand, "if you are using WLM (
Windows Live Messenger)
and you find the settings of the program hard, [we] can not recommend
Miranda IM. The typical things like WLM's smilies, sounds, winks and
games are not standard. You do get that functionality by the wide choice
of skins and plug-ins, but for that you do some research and setting
work."
Authors Lui and Chan in
Software Development Rhythms describe
using Miranda IM's plugin architecture to copy, modify, and test
existing plugins in order to develop "NAMMIK", a scriptable ICQ chatting
bot used to interview people; they refer to Miranda IM's architecture
as "simple and flexible".
Version 0.8.x
Version 0.8 of Miranda IM was released on June 17, 2009. It included a
new Account Manager which supports multiple accounts per protocol
(doing away with DLL renaming), built-in
SSL support, various enhancements and bugfixes for the core and plugins.
A PCWorld Magazine review of version 0.8.16 noted its addon
capability, but stated, "Miranda's user interface leaves something to be
desired" while referring to its login status icons, wishing for easier
management and grouping of contacts, easy blocking/reporting of
spammers, and ultimately recommending it "for those who use only surface
capabilities of instant messengers."
Version 0.9.x
Version 0.9 of Miranda IM was released on August 24, 2010. It
consists of many new features focused on improving Unicode support and
overall protocol improvements. It is also the first Miranda IM version
to feature an official 64-bit build.
Version 0.10.x
Version 0.10 of Miranda IM was released on July 18, 2012. It consists
of enhancements to Miranda IM 0.9.x including improved language support
and improved networking support.
Miranda NG
In May 2012 Miranda IM was forked to
Miranda NG
(New Generation). The reasons were differences in the development team
and slow-moving development of original Miranda. Main differences
between original client and fork are: moving to VS2010 compiler thus
deprecating ANSI version, core and plugins development is combined and
share unified repository.
