What is grommunio?

grommunio's feed publishes release pointers only; the changes themselves live on GitHub.

The crawled feed carries release-note stubs from 2022 to 2026, each the same sentence pointing to GitHub for the detailed logs. 2026.06.2 is the newest, published at the end of September. Nothing in the feed states what changed in any release.

What is Session?

Session survived its funding scare; now Pro is on hold and Protocol v2 is the bet.

Session's 2026 started with a cofounder's appeal warning the project might not continue, followed in June by news that community support had restored its runway. Since then the feed has tracked Session Pro: release preparation in August, a proposed change to Pro's tokenomics, a beta submitted to app stores in September, then in October a pause on the Pro launch while talks with an allied privacy ecosystem continue. Infrastructure work continued, with lighter Session Node software in mid-October.

grommunio vs Session: editorial side-by-side

G0.0

grommunio's feed publishes release pointers only; the changes themselves live on GitHub.

◆ Current state

The crawled feed carries release-note stubs from 2022 to 2026, each the same sentence pointing to GitHub for the detailed logs. 2026.06.2 is the newest, published at the end of September. Nothing in the feed states what changed in any release.

◆ Where it's heading

The only signal available is cadence, and it is thin and irregular: twelve published notes across roughly five years, with 2023.11.x, 2025.01.x and 2026.06.1 as the visible markers. That is a release-notes page maintained as an index rather than a changelog. Reading direction from grommunio would require the GitHub logs these notes point at.

◆ Prediction

Expect the next entry to be another dated pointer of the same form. Whether grommunio's real release cadence matches this feed cannot be determined from what is published here.

5.0

Session survived its funding scare; now Pro is on hold and Protocol v2 is the bet.

◆ Current state

Session's 2026 started with a cofounder's appeal warning the project might not continue, followed in June by news that community support had restored its runway. Since then the feed has tracked Session Pro: release preparation in August, a proposed change to Pro's tokenomics, a beta submitted to app stores in September, then in October a pause on the Pro launch while talks with an allied privacy ecosystem continue. Infrastructure work continued, with lighter Session Node software in mid-October.

◆ Where it's heading

Protocol v2, adding forward secrecy, post-quantum encryption and better linked-device handling, is now the main technical thread, with an invite-only alpha planned. Pro's monetisation model is in flux, so the revenue side remains unresolved.

◆ Prediction

Unclear whether Pro launches in its current form; the next concrete step is more likely a Protocol v2 alpha announcement.
