rlang vs stringr
A side-by-side editorial comparison of rlang and stringr — release velocity, themes, recent moves, and the top alternatives to consider.

rlang vs stringr: at a glance
What is rlang?
rlang moved tidyeval off R's private internals and onto official C API.
rlang is at 1.3.0, which rewrote hash() to walk objects itself rather than lean on R's serialiser — fixing stability against bytecode and shrinkable vectors, at the cost of invalidating every existing hash value. The release before it closed a multi-year effort: rlang and tidyeval are now fully backed by official C APIs of R, work the notes credit to collaboration with R core.
What is stringr?
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().

◆ Current state
rlang is at 1.3.0, which rewrote hash() to walk objects itself rather than lean on R's serialiser — fixing stability against bytecode and shrinkable vectors, at the cost of invalidating every existing hash value. The release before it closed a multi-year effort: rlang and tidyeval are now fully backed by official C APIs of R, work the notes credit to collaboration with R core.
◆ Where it's heading
The through-line across this whole window is one migration. Release after release retires something that depended on private R internals — env_browse(), env_unlock(), ns_registry_env(), the SEXP iterator now behind a compile flag — and replaces it with sanctioned API. The hash() rewrite in 1.3.0 is the same instinct applied to the serialiser: own the behaviour rather than inherit it.
◆ Prediction
With the C API migration declared complete in 1.2.0, the next releases are likely to be ordinary maintenance and type-checking additions rather than further defunct markings.

stringr keeps trading convenient guesses for predictable errors.
◆ Current state
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().
◆ Where it's heading
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.
◆ Prediction
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.
