What is CommaFeed?

A self-hosted RSS reader that now spends most of its release notes on security.

CommaFeed is a self-hosted Google Reader replacement that has spent the 6.x-to-7.x stretch rebuilding its trust boundaries rather than its feature list. SSRF protection has been tightened in four consecutive releases, feed parsing now strips javascript: URLs before they reach the database, and OPML imports are filtered against import-time abuse. The 7.x line pairs that with client interop: Fever API, ReadKit compatibility, and now the Google Reader API.

What is SiYuan?

SiYuan's v3.8.0 train restates one AI feature set across seven consecutive builds.

SiYuan is deep in a v3.8.0 preview train — four alphas and three betas since August 1 — and every build republishes the same four headline features: an AI Agent, semantic search over AI embeddings with reranking, Model Context Protocol support, and OIDC authentication. Two pairs of these builds carry byte-identical published notes, so the per-build delta is not visible from the feed at all. What does vary is a long enhancement list covering sync, mobile platforms and database views.

C
CommaFeed
COLLAB
5.0

A self-hosted RSS reader that now spends most of its release notes on security.

◆ Current state

CommaFeed is a self-hosted Google Reader replacement that has spent the 6.x-to-7.x stretch rebuilding its trust boundaries rather than its feature list. SSRF protection has been tightened in four consecutive releases, feed parsing now strips javascript: URLs before they reach the database, and OPML imports are filtered against import-time abuse. The 7.x line pairs that with client interop: Fever API, ReadKit compatibility, and now the Google Reader API.

◆ Where it's heading

The project is positioning itself as a sync backend other people's apps talk to, not just a web reader. Each release adds another protocol or client fix while hardening the assumption that an instance may be publicly exposed with untrusted users on it. The 7.0.0 swap from JEXL to sandboxed CEL and the 7.3.0 flip of blockLocalAddresses to a secure default both trade self-hoster convenience for a safer out-of-the-box posture.

◆ Prediction

Expect continued client-protocol coverage and further SSRF narrowing; the recurring pattern in these entries is that every new fetch path gets a follow-up hardening release.

6.3

SiYuan's v3.8.0 train restates one AI feature set across seven consecutive builds.

◆ Current state

SiYuan is deep in a v3.8.0 preview train — four alphas and three betas since August 1 — and every build republishes the same four headline features: an AI Agent, semantic search over AI embeddings with reranking, Model Context Protocol support, and OIDC authentication. Two pairs of these builds carry byte-identical published notes, so the per-build delta is not visible from the feed at all. What does vary is a long enhancement list covering sync, mobile platforms and database views.

◆ Where it's heading

The release notes are cumulative rather than incremental, which makes the train read as a single release delivered in installments. Beneath the repeated feature banner the actual work is platform breadth: LAN peer-assisted acceleration for cloud sync, audio recording on Android and HarmonyOS, custom font import on mobile, and configurable Stable, Beta and Alpha update channels. Reaching beta.3 within ten days of the first alpha says the train is converging.

◆ Prediction

A v3.8.0 stable release looks close given the move from first alpha to third beta inside ten days. The update-channel setting arriving in this same cycle suggests the project intends to keep running parallel preview streams once it ships.
