We're nearly up to 380 content management systems! We recently added detection methods for Contentful, SiteKreator and LeadPages. Since these are new system to WhatCMS.org, the market share calculations we have are artificially low. We expect, as we check and re-check more sites, their market share numbers to grow.
In addition to improving our detection coverage, we spent time beefing up our existing detection methods for BigCommerce, MantisBT. As with the new systems mentioned above, we may see the market share for these systems increase but we don't expect significant changes.
