What is Transmission?

Transmission rewrote its RPC API to JSON-RPC 2.0 — then the 4.1 beta train stalled.

The whole visible history is the 4.1.0 beta series, running from December 2024 to January 2026 and developed in parallel with the 4.0.x bug-fix line since 2023. Across those betas the client picked up sequential downloading, a selectable µTP-versus-TCP preferred transport, proxy support for web connections, IPv6 and dual-stack UDP trackers, native platform icons, and a JSON-RPC 2.0-compliant RPC API with snake_case unified across RPC and settings.json. Feature freeze was declared at beta.5 in January 2026, and nothing has shipped since.

What is RSS-Bridge?

The web's duct-tape RSS layer, now quiet for a year after flipping every bridge on by default.

RSS-Bridge generates feeds for sites that removed theirs, and each release is a batch of community fixes to individual bridges plus a handful of new ones. Releases are date-tagged rather than versioned and land every few months, with the most recent in August 2025 — roughly a year of silence since. The core is stable PHP; the churn is in the ~400 site-specific scrapers that break whenever a target site changes markup or adds bot protection.

Transmission rewrote its RPC API to JSON-RPC 2.0 — then the 4.1 beta train stalled.

◆ Current state

The whole visible history is the 4.1.0 beta series, running from December 2024 to January 2026 and developed in parallel with the 4.0.x bug-fix line since 2023. Across those betas the client picked up sequential downloading, a selectable µTP-versus-TCP preferred transport, proxy support for web connections, IPv6 and dual-stack UDP trackers, native platform icons, and a JSON-RPC 2.0-compliant RPC API with snake_case unified across RPC and settings.json. Feature freeze was declared at beta.5 in January 2026, and nothing has shipped since.

◆ Where it's heading

The interesting work is at the integration boundary, not in the download engine: the RPC surface has been standardised and renamed, and beta.5 was largely spent repairing what those changes broke, including backwards-incompatible keys accidentally written into settings files. That is the cost profile of an API migration in a project with a large ecosystem of third-party remotes. With feature freeze held for seven months and no 4.1.0 final, the release is late relative to its own stated plan.

◆ Prediction

The next release should be 4.1.0 final or a further beta rather than new features, since the branch is frozen — but the entries give no signal on what is holding it.

0.0

The web's duct-tape RSS layer, now quiet for a year after flipping every bridge on by default.

◆ Current state

RSS-Bridge generates feeds for sites that removed theirs, and each release is a batch of community fixes to individual bridges plus a handful of new ones. Releases are date-tagged rather than versioned and land every few months, with the most recent in August 2025 — roughly a year of silence since. The core is stable PHP; the churn is in the ~400 site-specific scrapers that break whenever a target site changes markup or adds bot protection.

◆ Where it's heading

The project has been shifting from a curated tool to a general-purpose scraping surface: bridges are now all enabled by default, caching was rewritten, and token-based URL auth was added to make public instances survivable. That combination points at operators running shared instances rather than individuals running one bridge. The maintenance load, however, is entirely community-carried, and the gap since the last release suggests that pipeline has thinned.

◆ Prediction

The next release is likely another routine batch of bridge repairs and additions rather than a core change. The stated intentions in these notes — raising the minimum PHP version and separating the document root from the data folder — remain unshipped, and nothing here indicates when that lands.
