rlang
rlang moved tidyeval off R's private internals and onto official C API.
A side-by-side editorial comparison of Prometheus and stringr — release velocity, themes, recent moves, and the top alternatives to consider.
Two branches running in parallel: 3.13 LTS on security patches, 3.14 promoting experiments to stable.
Prometheus is maintaining a 3.13 LTS line and a 3.5 line with security-only releases while 3.14 develops. The LTS patches have been narrow and serious — a head-chunk cache returning samples from the wrong chunk after truncation, a SIGBUS crash when the active query tracker's disk fills, plus CVE-driven dependency bumps in golang.org/x/text and gRPC. The 3.14.0 release candidate is where the feature work sits: duration expressions on by default, first_over_time promoted out of the experimental flag, and Oracle Cloud Infrastructure service discovery added.
stringr keeps trading convenient guesses for predictable errors.
stringr is at 1.6.0, which preserved names across the function set, made str_like() case sensitive to match the SQL operator it is named after, and changed str_replace_all() so a replacement function receives one vector of all values — faster, and breaking for anyone relying on the old call pattern. It also added str_ilike() and the programming-case helpers str_to_camel(), str_to_snake() and str_to_kebab().

PromQL is the centre of gravity. Features enter behind promql-experimental-functions or a dedicated flag, get renamed once while experimental (min/max to min_of/max_of), then graduate — first_over_time and duration expressions are the current graduates, start_timestamp the next candidate behind use-start-timestamps. The API is simultaneously being tightened, with the stats parameter deprecated ahead of rejection in the next major and credential forwarding across redirects already removed in 3.13. Service discovery keeps absorbing clouds as their APIs change, OCI added and a Hetzner label dropped in the same release.
A 3.14.0 final should follow the release candidate within weeks, carrying the duration-expression and first_over_time promotions with it.

It also added str_ilike() and the programming-case helpers str_to_camel(), str_to_snake() and str_to_kebab().
Every substantial release in this window removes an accommodation. 1.5.0 enforced tidyverse recycling rules so only length-1 vectors recycle, turned many warnings into errors, and made str_detect() with an empty string an error rather than a silent TRUE. 1.6.0 continues that: the functions guess less and reject more, and each round trades a convenience for a predictable failure.
With str_like(ignore_case) newly deprecated, the next release most likely completes that removal and continues aligning behaviour with SQL string operators rather than adding a new function family.
