httpuv
httpuv ships almost nothing, which is what you want from the web server under Shiny
A side-by-side editorial comparison of later and Zeebe — release velocity, themes, recent moves, and the top alternatives to consider.
later spends its releases keeping R's event loop compiling against moving toolchains.
later provides the event loop that lets R schedule callbacks, underpinning shiny, httpuv and most async work in the language. Recent releases are overwhelmingly build and compatibility work: Rcpp error-handling changes, a C23 namespace collision with glibc, and header ordering to satisfy Rcpp auto-includes.
Camunda's 8.10 alpha threads business IDs through the stack while the tag feed fills with CI noise.
Zeebe's public tag stream is dominated by monorepo automation: renovate dependency bumps, backport tags and CI hardening published as `0.0.0-dryrun-*` releases. The substantive work sits in the 8.10.0-alpha4 line, where late business ID assignment landed across the engine, REST, gRPC and the Java client at once. Maintenance branches 8.7 through 8.9 continue to take security and stability backports in parallel.

The API is settled enough that the release calendar is set by the surrounding ecosystem rather than by any feature plan. 1.4.5 cleaned house by dropping pre-unwind-protect fallbacks, and 1.4.6 carries the only recent change a user would notice at all — lower CPU use when idle at the console.
Expect further releases pinned to compiler and Rcpp changes, with the observable surface staying essentially where it is.

Maintenance branches 8.7 through 8.9 continue to take security and stability backports in parallel.
Camunda is building 8.10 as a correlation-identity release: business IDs propagate from job completion through the engine into secondary storage, which is the groundwork for tracing a process instance by a domain key rather than an internal one. The alpha4 line has now moved from rc1 through rc2 to a full alpha with the same feature set, so the surface is stabilising rather than expanding. Four supported branches receiving concurrent backports signals the enterprise support burden is shaping release cadence as much as new capability.
Expect 8.10.0-alpha5 or a beta that consolidates the business ID surface and starts exercising it in Operate and Tasklist queries. Whether anything beyond business IDs is targeted for 8.10 is not visible in these entries.
