grommunio vs RSS.com: at a glance
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 RSS.com?
RSS.com's changelog is back after ten months, with listener voicemail for podcasts.
RSS.com is a podcast hosting platform. After a public API in December 2025 its changelog went silent until v26.10.1 in October, which lets listeners leave voicemails for a show through a link in the episode notes. Earlier releases added Podcasting 2.0 location tags and a year of analytics lookback.

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.
RSS.com
2.5COMMS
RSS.com's changelog is back after ten months, with listener voicemail for podcasts.
◆ Current state
RSS.com is a podcast hosting platform. After a public API in December 2025 its changelog went silent until v26.10.1 in October, which lets listeners leave voicemails for a show through a link in the episode notes. Earlier releases added Podcasting 2.0 location tags and a year of analytics lookback.
◆ Where it's heading
The October release points toward listener interaction rather than the developer and metadata work of late 2025. One entry after a long gap is too little to call a new direction.
◆ Prediction
Unclear: a single release after ten quiet months doesn't establish a cadence, so the next move can't be read from the entries.
