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().

What is Vitest?

Vitest 5 reaches RC after a beta line that reworked config, mocking defaults, and the browser runner.

Vitest has spent the last two and a half months in a v5.0.0 beta train, and 5.0.0-rc.1 is the first release candidate. Each beta carried its own block of breaking changes rather than deferring them: config lookup no longer walks ancestor directories, @vitest/runner was inlined and unpublished, webdriverio was dropped, mocks now clear before each test by default, and reporter output moved to a .vitest directory. The RC adds nested projects, a shared Vite server across inline projects, and a failure when an asynchronous assertion is never awaited.

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.

5.0

Vitest 5 reaches RC after a beta line that reworked config, mocking defaults, and the browser runner.

◆ Current state

Vitest has spent the last two and a half months in a v5.0.0 beta train, and 5.0.0-rc.1 is the first release candidate. Each beta carried its own block of breaking changes rather than deferring them: config lookup no longer walks ancestor directories, @vitest/runner was inlined and unpublished, webdriverio was dropped, mocks now clear before each test by default, and reporter output moved to a .vitest directory. The RC adds nested projects, a shared Vite server across inline projects, and a failure when an asynchronous assertion is never awaited.

◆ Where it's heading

The through-line across beta.4 to rc.1 is consolidation of the runner's architecture — one config resolution path, one Vite server, one project tree that can nest — paired with defaults that surface mistakes instead of tolerating them (strict toHaveTextContent, hoistable-scope errors, unawaited assertions failing). The browser mode is being narrowed to a single first-party stack rather than a plugin matrix. Performance work is now targeted at memory retention in vm pools and large --changed graphs, which reads as pre-GA cleanup rather than new capability.

◆ Prediction

With breaking changes still landing in rc.1, expect at least one more RC to settle the nested-projects and shared-server behaviour before a v5.0.0 final.
