What is httr?

httr's last releases are housekeeping - the package now points users at httr2

httr is in wind-down. The last release with real feature work was 1.4.0 in 2018; everything since is test stabilization, CRAN-driven fixes, and unwinding a dependency on the httpbin service. Version 1.4.7 removed the vignette contents outright and redirects readers to httr2.

What is Prometheus?

Prometheus 3.14 ships the release candidate unchanged, duration expressions now on by default

3.14.0 is byte-identical to the 3.14.0-rc.0 body published a week earlier, so the stable cut carries exactly what the candidate previewed: PromQL duration expressions enabled by default with the feature flag retired, first_over_time promoted to stable, Oracle Cloud service discovery added, and a set of start-timestamp experiments still behind flags. The performance work is the substantive half, with regex matchers on literal alternations, native histogram scrape parsing down roughly 49% in allocations, and a recursion-free text parser that closes a stack-overflow path on hostile exposition.

httr's last releases are housekeeping - the package now points users at httr2

◆ Current state

httr is in wind-down. The last release with real feature work was 1.4.0 in 2018; everything since is test stabilization, CRAN-driven fixes, and unwinding a dependency on the httpbin service. Version 1.4.7 removed the vignette contents outright and redirects readers to httr2.

◆ Where it's heading

This is a succession, not a decline. The maintainers are keeping httr installable and passing checks for the very large base of packages that depend on it, while all design work happens in httr2. The pattern across these six releases is unambiguous: nothing lands here unless CRAN, a test service, or a platform forced it.

◆ Prediction

Expect continued patch releases driven only by CRAN checks and toolchain changes; the interesting HTTP work in R will keep landing in httr2.

Prometheus 3.14 ships the release candidate unchanged, duration expressions now on by default

◆ Current state

3.14.0 is byte-identical to the 3.14.0-rc.0 body published a week earlier, so the stable cut carries exactly what the candidate previewed: PromQL duration expressions enabled by default with the feature flag retired, first_over_time promoted to stable, Oracle Cloud service discovery added, and a set of start-timestamp experiments still behind flags. The performance work is the substantive half, with regex matchers on literal alternations, native histogram scrape parsing down roughly 49% in allocations, and a recursion-free text parser that closes a stack-overflow path on hostile exposition.

◆ Where it's heading

The project is spending its feature budget on start timestamps, appearing across PromQL, TSDB encoding, and remote write V2 in the same release but held behind use-start-timestamps and histograms-st-encoding. Everything else follows the established rhythm of promoting one experimental function per cycle and adding a cloud discovery source. The API deprecations are being staged carefully, warning now and rejecting at the next major.

◆ Prediction

Start timestamps are the obvious candidate to lose their feature flags once the encoding and remote-write halves have run together, and the stats parameter values now warned on will be rejected in the next major.
