What is ipumsr?

ipumsr is collapsing a dozen collection-specific APIs into one extract vocabulary.

ipumsr is the R client for the IPUMS API, covering microdata, aggregate-data and now DHS collections. The dominant work of the last two years has been replacing per-collection functions with generic ones: define_extract_micro() for all microdata, then define_extract_agg() and read_ipums_agg() for the aggregate projects. Each new collection now arrives as an argument value rather than a new function.

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.

ipumsr is collapsing a dozen collection-specific APIs into one extract vocabulary.

◆ Current state

ipumsr is the R client for the IPUMS API, covering microdata, aggregate-data and now DHS collections. The dominant work of the last two years has been replacing per-collection functions with generic ones: define_extract_micro() for all microdata, then define_extract_agg() and read_ipums_agg() for the aggregate projects. Each new collection now arrives as an argument value rather than a new function.

◆ Where it's heading

The package is converging on a single extract-definition surface, and it is retiring the old path rather than keeping both. Collection-specific functions have moved through deprecation to defunct within about two release cycles, and legacy spatial and codebook readers have been dropped outright along with their raster and sp dependencies. The cost is paid by users: each generalization has broken working code.

◆ Prediction

The remaining collection-specific entry points, chiefly the NHGIS-named ones, are the obvious next candidates for deprecation, and further IPUMS projects will most likely be added as collection arguments rather than new functions.

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.
