Corteza vs Fat Free CRM: at a glance
What is Corteza?
Corteza 2026.9.0 goes final after a week of single-fix candidates.
Corteza shipped 2026.9.0 on October 19, closing a run of release candidates that each fixed one edge: MySQL 8 cast checks in rc.4, deny rules in permission reports in rc.5 and MySQL-compatible reminder timestamps in rc.6. The release entry only links to the 2026.9 changelog. Before this, the feed was a slow patch train on the 2024.9 line, ending at 2024.9.10 in late August.
What is Fat Free CRM?
Fat Free CRM's only tracked release is a test tag that pins the Ruby platform back to 3.4.
Fat Free CRM, the open-source Rails CRM, has one tracked entry: an April 2026 GitHub release tagged "test" that normalizes the platform setting and drops back to Ruby 3.4. It is build configuration, not a feature release.

Corteza
5.0CRM
Corteza 2026.9.0 goes final after a week of single-fix candidates.
◆ Current state
Corteza shipped 2026.9.0 on October 19, closing a run of release candidates that each fixed one edge: MySQL 8 cast checks in rc.4, deny rules in permission reports in rc.5 and MySQL-compatible reminder timestamps in rc.6. The release entry only links to the 2026.9 changelog. Before this, the feed was a slow patch train on the 2024.9 line, ending at 2024.9.10 in late August.
◆ Where it's heading
The jump from 2024.9 to 2026.9 opens a new major line after two years on the old one. Two of the final three fixes targeted MySQL, which suggests the release was validated across database backends. What the new line adds for users still isn't visible in the feed.
◆ Prediction
Expect 2026.9.x patch releases to follow the same pattern as 2024.9, with occasional fixes over months. Whether 2024.9 keeps receiving patches is unclear from the entries.
Fat Free CRM
0.0CRM
Fat Free CRM's only tracked release is a test tag that pins the Ruby platform back to 3.4.
◆ Current state
Fat Free CRM, the open-source Rails CRM, has one tracked entry: an April 2026 GitHub release tagged "test" that normalizes the platform setting and drops back to Ruby 3.4. It is build configuration, not a feature release.
◆ Where it's heading
One CI-facing tag is too little to read a direction from. The Ruby version pin hints at maintenance work keeping the app on a supported runtime rather than new CRM capability.
◆ Prediction
The entries don't support a confident prediction; a tagged versioned release would be the first signal of where the project is heading.
