Important: This website is now read only (except to admins) to comply with the UK Online Safety Act. Composr CMS is in the process of migrating to a new Constitutional governance model and Bazaar development model, with functionality of the old website (constructed by ocProducts Ltd, the prior copyright holder, a UK company) spread between GitLab and the new website (which has no connections to the UK).
A new version, 10.0.52 is available. Upgrading to 10.0.52 is considered strongly advised by ocProducts for v10 sites planning to upgrade later to v11 due to upgrader and tar.php fixes. There may have been other upgrades since 10.0.52 - see the ocProducts news archive.
