BIOMASS vs Skipper: at a glance
What is BIOMASS?
A tropical-forest biomass staple modernising its geospatial stack without saying so
BIOMASS estimates aboveground biomass and its uncertainty in tropical forests and is well established in that niche. Its public changelog is close to empty: the most recent entry, 2.2.4, is a thirty-four character pointer to the NEWS file. The last release with readable content, 2.1.11, bundled six versions of work whose substantive part was migrating off sp and raster to sf and terra, and from httr to httr2.
What is Skipper?
Skipper trims a 4x memory regression out of routesrv, days after shipping h2c
Zalando's HTTP router ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.63, which stops routesrv holding an uncompressed route tree alongside the compressed buffer: retained memory in the release's own benchmark falls from 30.7 MB to 2.0 MB, undoing most of the 4x increase zone-aware routing had introduced. Around it sit narrow auth repairs, and an eskip parser change that finally accepts negative numeric arguments in predicates and filters.

A tropical-forest biomass staple modernising its geospatial stack without saying so
◆ Current state
BIOMASS estimates aboveground biomass and its uncertainty in tropical forests and is well established in that niche. Its public changelog is close to empty: the most recent entry, 2.2.4, is a thirty-four character pointer to the NEWS file. The last release with readable content, 2.1.11, bundled six versions of work whose substantive part was migrating off sp and raster to sf and terra, and from httr to httr2.
◆ Where it's heading
The visible arc is dependency modernisation and CRAN compliance rather than science: retiring sp and raster ahead of their deprecation, failing gracefully when taxonomic services are unreachable, and repeatedly changing taxonomic backend as those services disappeared — taxosaurus to TNRS, then away from Tropicos once it was no longer maintained. The recurring fragility is correctTaxo(), which depends on third-party name resolution outside the maintainers' control.
◆ Prediction
Expect the next release to be another compliance or dependency response; on this feed's record the release notes will not say what changed, leaving the NEWS file as the only reliable source.

Skipper trims a 4x memory regression out of routesrv, days after shipping h2c
◆ Current state
Zalando's HTTP router ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.63, which stops routesrv holding an uncompressed route tree alongside the compressed buffer: retained memory in the release's own benchmark falls from 30.7 MB to 2.0 MB, undoing most of the 4x increase zone-aware routing had introduced. Around it sit narrow auth repairs, and an eskip parser change that finally accepts negative numeric arguments in predicates and filters.
◆ Where it's heading
Two threads run through the recent tags. The data path keeps getting real work - leastRequests balancing, then h2c end to end in v0.27.57, now the memory cost of zone-aware routing being paid back. The auth filters, by contrast, are only being maintained: token introspection, grant auth, and now the OIDC Referer handling are fixes rather than new capability, and several are follow-ups to each other rather than independent bugs.
◆ Prediction
Zone-aware routing looks like the source of the recent memory attention, so expect further tuning around route storage and the hash computation done on every pull, which the release's second benchmark already isolates. The OIDC cookie change is the second link in an auth chain that started with the grant-auth fix, and is likely to draw another follow-up.
