CloudStack ships two LTS branches in lockstep and publishes nothing but pointers
A side-by-side editorial comparison of rextendr and Verdaccio — release velocity, themes, recent moves, and the top alternatives to consider.
rextendr put Rust-backed R packages in the browser, then tore itself down for a 1.0.0 rebuild
rextendr is the R-side toolchain for extendr, scaffolding and compiling R packages with Rust internals. The package is mid-teardown: the 0.4-final tag in October 2025 warns that main may not work as expected and directs users to install from that tag, and April 2026's release is titled as one more developer release before 1.0.0. Meanwhile the CRAN-facing 0.4.x line did the substantive work.
Verdaccio's 7.0 line is subtraction — forks dropped, toolchain swapped, tags mostly empty
The next-7 prerelease line is short and almost entirely maintenance. Its one substantive release adopted @verdaccio/server and deleted the local api, web, and storage forks, leaving a thin Storage wrapper behind only to keep callback-based storage plugins working. Everything since has been dependency retargeting, a lint and format toolchain swap, and a tag whose body reads 'chore: trigger release'.

Meanwhile the CRAN-facing 0.4.x line did the substantive work.
Two threads run in parallel. The first is reach: 0.4.0 added WebR support out of the box for all extendr packages by enabling the wasm32-unknown-emscripten target, and 0.4.2 followed with the panic and link-time-optimization settings needed to make those builds actually work. The second is CRAN compliance — use_cran_defaults(), vendor_pkgs(), automatic SystemRequirements fields, and configure scripts, all aimed at getting Rust-powered packages accepted on CRAN. The rebuild announced in 0.4-final is a third thread whose shape the entries do not reveal.
The stated destination is 1.0.0 built on the new Makevars-linked build process, so that release is the next milestone. What the revamp changes for existing extendr packages is not described in any entry here.

This is consolidation ahead of a major: the project is collapsing code it had been carrying in-tree back onto shared packages and standardising tooling around oxlint and oxfmt. The remaining compatibility shim is the visible unfinished business — it exists purely for legacy plugins, and it is the last thing standing between this line and a clean server dependency.
Removing the legacy storage wrapper is the decision this line is heading toward, and it breaks callback-based storage plugins when it lands, so expect it to arrive with the 7.0.0 final rather than in another next tag. Until then the prerelease stream will keep producing tags with no user-visible content.
