Cronicle vs Transmission: at a glance
What is Cronicle?
Cronicle closes three permission holes in two days, including API key exposure.
After weeks of single-dependency bumps, Cronicle shipped two security fixes. 0.9.141 restricts run_event overrides so a plugin cannot be swapped, and 0.9.142 blocks restricted accounts from chain reactions and stops API keys leaking into objects and audit metadata. Earlier October releases bumped pixl-tools, pixl-mail and sanitize-html.
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.

Cronicle
5.0INFRA · APIS
Cronicle closes three permission holes in two days, including API key exposure.
◆ Current state
After weeks of single-dependency bumps, Cronicle shipped two security fixes. 0.9.141 restricts run_event overrides so a plugin cannot be swapped, and 0.9.142 blocks restricted accounts from chain reactions and stops API keys leaking into objects and audit metadata. Earlier October releases bumped pixl-tools, pixl-mail and sanitize-html.
◆ Where it's heading
The 0.9.x line is in maintenance, but the focus has moved from upstream vulnerabilities to Cronicle's own permission model. Releases arrive every few days.
◆ Prediction
Expect more permission and privilege fixes in the next 0.9.x builds; no feature work is visible.
Transmission
0.0INFRA · APIS
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.
