ASP.NET Core vs withr: at a glance
What is ASP.NET Core?
ASP.NET Core's public feed is servicing traffic; the real work happens on the .NET 11 previews.
The repository ships on a predictable servicing rhythm — monthly patch rollups across the 8.0, 9.0, and 10.0 branches, dominated by branding bumps, dependency updates, and build-infrastructure work. User-visible changes are rare and concentrated in the 10.0 line, where Blazor fixes still land. The 11.0 preview tags appear separately and carry single commits rather than release notes.
What is withr?
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.

ASP.NET Core's public feed is servicing traffic; the real work happens on the .NET 11 previews.
◆ Current state
The repository ships on a predictable servicing rhythm — monthly patch rollups across the 8.0, 9.0, and 10.0 branches, dominated by branding bumps, dependency updates, and build-infrastructure work. User-visible changes are rare and concentrated in the 10.0 line, where Blazor fixes still land. The 11.0 preview tags appear separately and carry single commits rather than release notes.
◆ Where it's heading
Nothing in this feed suggests a directional shift: the 8.0 and 9.0 branches are in maintenance, 10.0 absorbs the remaining behavioral fixes, and 11.0 is accumulating previews one commit at a time. Recent servicing entries lean unusually heavily toward CI and internal feed authentication work — the team replacing expired PATs with build identity and moving pipelines to newer images. Read this feed for stability signals, not for product direction.
◆ Prediction
The cadence points to continued monthly servicing across all three branches, with .NET 11 preview tags accumulating until a preview release note consolidates them into something readable.

withr rebuilt defer() on base R's own on.exit(), and got much faster for it
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
