[3] Most of the early major releases were named after famous cities or particular places [4] the project maintainer has visited and/or was inspired by.

b2evolution 5.0 was rapidly adopted, becoming the most popular version,[6] but overall b2evolution usage is declining relative to competitors WordPress and Drupal.

Known primarily for its multi-blog capabilities,[7] b2evolution also includes "all the features of traditional blog tools"[8] like file & photo management, advanced skinning, multiple domain support, detailed user permissions, and W3C standards compliance.

These include text format extensions enabling Textile, Auto-P, Greymatter, BB code, Texturize, LaTeX, and graphic smilies.

Other features include community-wide spam filters, in which many b2evolution sites aggregate and tag spammer IPs into a central blacklist for the benefit of all b2evolution blogs,[citation needed] a button to declare "comment spam bankruptcy"—which deletes all comments across an entire b2evolution installation, a fully skinnable interface, strong SEO features including automatic redirection of renamed articles and insertion of canonical link tags, url shortening, localization into a dozen language packs, and a fully exposed API for plugin developers to add new functionality.
