Appwrite is spending this quarter on latency: the CLI, cold starts, and now builds.
Appwrite Cloud is being tuned end to end for speed. The CLI was rewritten from Node to a single Go binary, function cold starts now mount a compressed SquashFS artifact instead of extracting files, and builds cache the package manager's store between runs. Alongside that, the MCP thread went both ways in a fortnight: Appwrite's own MCP server moved to a hosted remote endpoint, and a Functions template turned the platform into somewhere to host your own. Cloud economics are tightening in the background, with build and deployment storage billed from September 1 and scheduled executions jittered on Free and Education plans.
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.

Every performance entry in this window targets the same path: the loop between a code change and a running deployment. Install time, extraction time, process start time — each is being removed in turn, with real before-and-after numbers rather than claims. That path matters most when something invokes it repeatedly, which is where the CLI rewrite and the MCP work point: CI pipelines and coding agents driving a project through its own tooling. The pricing changes run on a parallel track, drawing the line between what is free and what is guaranteed.
The cold-start work is currently limited to new deployments and favours larger artifacts, so extending it — or automating the redeploy it requires — is the obvious follow-up. The September 1 storage enforcement is dated and will land; expect deployment retention controls to get more attention as it approaches.

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.
