The record

Purpose: PmWiki is a wiki-based content-management system for collaboratively creating and maintaining websites.
Editing: Pages can be edited and added through the web without requiring users to know HTML or CSS.
Access control: Password protection can be set for an entire site, page groups, or individual pages, and can control reading, editing, and uploads.
Authentication integrations: The access control system can work with existing password databases such as .htaccess, LDAP, and MySQL.
Extensibility: Administrators can customize markup and add features through extensions called recipes in the PmWiki Cookbook.
Storage: PmWiki stores pages as flat files and does not require a database; its features page says it can handle thousands of pages.
Customization: Site administrators can change appearance and functions using skins and HTML templates.
History: Page histories include restore links, and the number of history days and revisions can be configured.
Security update: Release 2.7.5 closed a vulnerability affecting PmWiki versions 2.0.0 through 2.7.4 on Windows servers under certain editing and read-protection conditions.
Privacy update: In version 2.7.6, page histories reveal edit IP addresses only to administrators.
Current release: The release notes list version 2.7.6, dated 2026-09-18, and say it includes updates for recent PHP versions.
Support: The project lists a FAQ, troubleshooting guide, error-message descriptions, and mailing lists as free user-support resources.
Paid services: PmWiki maintainer Petko Yotov offers paid technical support and development at 60€ per hour and says an invoice will be provided.
Maintainer location: The support page lists Petko Yotov's address in La Ferté-sous-Jouarre, France.
