Corteza vs Membrain: 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 Membrain?
Membrain's recent changelog is editorial content only — no product releases visible

Corteza vs Membrain: editorial side-by-side
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.
Membrain
5.0CRM
Membrain's recent changelog is editorial content only — no product releases visible
◆ Current state
All of Membrain's logged entries are blog posts and podcast episodes about sales management philosophy, AI adoption in sales, and sales leadership. There are no product release notes, feature announcements, or capability changes in the recent entry set. The publication cadence is roughly weekly.
◆ Where it's heading
The content themes — AI in sales, sales manager evolution, cold calling best practices — align with Membrain's sales CRM positioning, but the actual product roadmap isn't readable from editorial content alone. Without product changelog data, the product's current capability state and direction cannot be assessed.
◆ Prediction
Without actual product changelog data, no grounded prediction is warranted. The editorial content reflects the company's thought leadership strategy but reveals nothing about the product shipping cadence.
