Liquidsoap vs Pelican: at a glance
What is Liquidsoap?
Liquidsoap opens its 2.5 line with subtitles as a first-class content type and a streaming server of its own
The 2.5.x rolling release carries the accumulated 2.5.0 changelog, and it is the largest body of work Liquidsoap has staged in over a year. Subtitles become a dedicated content type alongside audio and video, with native SRT decoding, FFmpeg subtitle encode and decode, bitmap passthrough, callbacks, transformations and dynamic insertion. An Icecast-compatible server ships as icecast.server, with source authentication, mount points, relay and per-listener encoding. Underneath, the source composition model was rewritten: switch, fallback, rotate and random drop their parallel list parameters for per-source methods, and switching now fades by default.
What is Pelican?
Pelican now ships roughly once a year, and 4.12 is theme housekeeping
Pelican is a mature Python static site generator in low-cadence maintenance: 4.12.0 in April 2026 followed 4.11.0 by fifteen months, which itself followed 4.10.0 by sixteen. Nearly all recent work lands in the bundled notmyidea and Simple themes, in summary generation, and in the file-watching and logging plumbing. The contributor pattern is telling — a handful of names carry most merged PRs, and the changelogs read as accumulated small fixes rather than planned feature arcs.

Liquidsoap opens its 2.5 line with subtitles as a first-class content type and a streaming server of its own
◆ Current state
The 2.5.x rolling release carries the accumulated 2.5.0 changelog, and it is the largest body of work Liquidsoap has staged in over a year. Subtitles become a dedicated content type alongside audio and video, with native SRT decoding, FFmpeg subtitle encode and decode, bitmap passthrough, callbacks, transformations and dynamic insertion. An Icecast-compatible server ships as icecast.server, with source authentication, mount points, relay and per-listener encoding. Underneath, the source composition model was rewritten: switch, fallback, rotate and random drop their parallel list parameters for per-source methods, and switching now fades by default.
◆ Where it's heading
Liquidsoap is expanding on two axes at once. It is broadening what a stream can carry - subtitles are a third content modality in a system that has understood two - and it is moving up the stack from a source that feeds Icecast into something that can be the Icecast. The language work points the same way: a source(_) type for unknown content, callback release semantics, and effect-scoped clocks are the kind of changes made when scripts are getting large enough that lifetime and typing errors cost real production time.
◆ Prediction
The 2.5.0 final should follow the rolling branch within a release cycle, and the migration guide already shipped for the composition parameter changes suggests the breaking surface is considered settled. Watch whether subtitle support reaches the harbor and Icecast server paths, which the current notes do not say.
Pelican
0.0DEVOPS
Pelican now ships roughly once a year, and 4.12 is theme housekeeping
◆ Current state
Pelican is a mature Python static site generator in low-cadence maintenance: 4.12.0 in April 2026 followed 4.11.0 by fifteen months, which itself followed 4.10.0 by sixteen. Nearly all recent work lands in the bundled notmyidea and Simple themes, in summary generation, and in the file-watching and logging plumbing. The contributor pattern is telling — a handful of names carry most merged PRs, and the changelogs read as accumulated small fixes rather than planned feature arcs.
◆ Where it's heading
The project is stable rather than growing: the last genuinely structural changes were switching the build tool to PDM and moving file watching to watchfiles back in 4.9.0, and nothing since has altered how Pelican works. Recent releases invest in making the bundled themes usable as inheritance bases — more template blocks, CSS_FILE support, dark mode — which pushes customization toward theme authors instead of core. Expect continuity, not reinvention.
◆ Prediction
The entries show no roadmap signal beyond incremental theme and Python-version support, so the next release most likely follows the same pattern: another year-scale gap, more Simple-theme inheritance hooks, and test-matrix updates for a newer Python.
