OpenEMM moved to its 26.05 line in July with a full frontend and backend GA build. Since then only frontend builds have followed (26.05.111 in September, 26.05.132 in October). Earlier lines (25.11, 25.04) got maintenance releases into December 2025. No entry describes actual changes.
What is SendPortal?
SendPortal hasn't tagged a release since July 2020.
The only tracked release is v1.0.3 from July 2020, which removed the laracatch-client dependency. No later tags appear in the feed, so for tracking purposes the project looks dormant.

OpenEMM
2.5MKT AUTO
OpenEMM ships versioned builds on schedule, with no notes on what changed.
◆ Current state
OpenEMM moved to its 26.05 line in July with a full frontend and backend GA build. Since then only frontend builds have followed (26.05.111 in September, 26.05.132 in October). Earlier lines (25.11, 25.04) got maintenance releases into December 2025. No entry describes actual changes.
◆ Where it's heading
The pattern is roughly two feature lines a year, then frontend-only builds and backported maintenance. The direction of the product can't be read from version numbers alone.
◆ Prediction
Another 26.05 frontend build in the next one to two months fits the cadence; the next major line's timing and content are unclear from the entries.
