Since RFC 1459 was published, the new features in the irc2.10 implementation led to the publication of several revised protocol documents (RFC 2810, RFC 2811, RFC 2812 and RFC 2813); however, these protocol changes have not been widely adopted among other implementations.
RFC 1459 publitseerimisest saati on uute, irc2.10 versioonis lisandunud võimaluste kohta avaldatud mitu sarnast dokumenteeringut (RFC 2810, RFC 2811, RFC 2812, RFC 2813), kuid need muutused protokollis ei ole leidnud laialdast kasutust.
