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.
Tigris keeps publishing its architecture, and the newest post opens up the storage engine itself.
This feed is Tigris's engineering blog, and it alternates between protocol critique and descriptions of how the product answers it. The most recent post opens the internals: how Tigris composes ACID metadata, global placement, caching, replication, and background work on FoundationDB into a multi-region object store. Before it came the Recycle Bin — deletion of objects and buckets on top of immutable storage in an active-active geo-replicated database — plus two posts dissecting SigV4 and presigned URLs, and one on agent-native onboarding through tigris init --agent.

Each new collection now arrives as an argument value rather than a new function.
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.
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.

The writing is doing product work. Each protocol post establishes a problem — SigV4's canonicalization and clock skew, presigned URLs as deliberate replay attacks, S3 egress pricing on ClickHouse restores — and positions Tigris behavior as the answer, which makes the blog a migration funnel rather than a changelog. The architecture post is a different move: publishing the FoundationDB composition is a credibility play aimed at buyers who need to believe a newer object store can hold multi-region data.
Expect the protocol-critique-then-Tigris-answer format to continue, with the egress-cost framing recurring as the clearest paid migration path. Feature announcements will likely stay embedded in essays rather than appearing as release notes.
