httpuv
httpuv ships almost nothing, which is what you want from the web server under Shiny
A side-by-side editorial comparison of TypeDB and withr — release velocity, themes, recent moves, and the top alternatives to consider.
TypeDB is making the query path cheaper and the schema finally editable.
The 3.11 and 3.12 lines have been a run of server-side correctness and operability work: a driver compatibility floor that rejects anything older than 3.11.0, connect hints printed at startup, pre-created UUIDs for users so a distributed deployment can share state, transaction close made synchronous instead of fire-and-forget, and RocksDB cache and write-buffer limits exposed as configuration. The newest release splits the old compilation cache into separate parse, translation and compile stages, and adds type renaming through redefine.
withr rebuilt defer() on base R's own on.exit(), and got much faster for it
withr provides the with_ and local_ functions that temporarily change global state and restore it on exit - the cleanup primitive under most of the tidyverse test suites. Version 3.0.0 reimplemented defer() as a thin wrapper over base::on.exit(), which the maintainers made possible by contributing the required arguments to R 3.5 itself. Everything since has been small correctness work.

Two threads are visible. One is making the engine predictable for operators — memory budgets, transaction guarantees, explicit version floors. The other is reducing per-query cost now that the given stage makes string-identical queries common, which is why parsing is separated from translation and can happen without a transaction. Type renaming is the first real schema-evolution affordance in this window, and it arrived alongside the caching work rather than as its own release.
Expect the cache split to be followed by invalidation tuning, since translation and compile caches flush on schema commits and statistics drift, and further redefine-based schema evolution now that renaming works.

Everything since has been small correctness work.
The arc here is a package pushing its own machinery down into base R and then living off the result. Once defer() became on.exit(), the remaining work is about where cleanup is allowed to happen - knitr documents, source() calls, the global environment, session end - and about restoring state correctly when an expression exits early. Releases are now infrequent and CRAN-driven.
Expect continued low-volume releases fixing edge cases in where deferred handlers run; with the core delegated to base R, there is little left that would prompt a larger change.
