Encryption

There is also a Pidgin-Encryption plugin, which uses RSA Encryption.^[3]

Naming dispute

Pidgin was originally known as 'GTK+ AOL Instant Messenger'. In response to pressure from AOL, the program was renamed to the acronymous-but-lowercase 'Gaim'. As AOL's IM program AOL Instant Messenger gained popularity, AOL trademarked its acronym, "AIM", leading to a lengthy legal struggle with the program's creators, who kept the matter largely secret.
On April 6 2007, the project development team announced the results of their settlement with AOL, which included a series of name changes: ''Gaim'' would become ''Pidgin'', ''libgaim'' would become ''libpurple'', and ''gaim-text'' would become ''finch''.^[4] The name Pidgin was chosen in reference to the term "pidgin", which describes communication between people who do not share a common language. ^[5] It also harks back to its original name, as the pigeon bird is a popular game bird and messenger. The name "purple" refers to "prpl", the internal libgaim name for an IM protocol.
Due to the legal issues, version 2.0 of the software was frozen in beta stages. Following the settlement, it was announced that the first official release of Pidgin 2.0.0 was hoped to occur during the two weeks from April 8, 2007.^[6] However, Pidgin 2.0 did not release as scheduled, and on April 22, 2007, Pidgin developers announced the reason for the delay having to do with the preferences folder ".gaim".^[7]
Pidgin 2.0.0 was released on May 3, 2007. This was the first release version to be called Pidgin, and contained a completely new graphics design.^[8]

Criticisms and current deficiencies

:''See The Pidgin developer site for the current list of outstanding issues.''
Because the Pidgin project uses reverse-engineering to interact with some proprietary protocols, there are disparities in functionality between official clients and the Pidgin client.
File transfers through the .NET protocol are slow, as data is routed through MSN servers to the receiver, instead of utilizing a faster peer-to-peer functionality.^[9] A Google Summer of Code project aims to add peer-to-peer functionality in 2007.^[10]
Like similar programs, saved passwords are stored in a cleartext file. This password file is readable by anyone who uses the same user account on that computer, or to anyone who has access to the administrative account. (The reason for this is that saved passwords must be stored in a way that is readily accessible to the program. If they were encrypted by the application, decryption by third parties would only require access to the application's source code, including any encryption key. The developers believe that saving the passwords in a cleartext format avoids a false illusion of security.^[11])
Pidgin does not currently support video and audio conferencing. ^[12] The developers plan on implementing multimedia messaging in the future,^[13][14] but there has been parallel development with the uncompleted 'gaim-vv' library.
The GTK+ build packaged with Pidgin has been known to cause errors with GIMP in Windows.^[15] This was, however, determined to be a bug in GIMP, which made improper assumptions about configuration files.^[16]
