## [Unreleased]

## [3.1.1] — 2026-11-07

Crafted request headers can no longer grow a process for good or make it raise.

**Fixed**
- Version checks no longer fill RubyGems' process-wide `Gem::Version` cache: 20,000 user agents with unique macOS
versions grew a process by 200 MB.
- An Accept-Language header listing more than 32 languages is parsed on each request instead of cached: 1,000 such
headers held 107 MB.
- Bytes that are not valid UTF-8 in the user agent or the Accept-Language header become U+FFFD instead of raising
`ArgumentError`, and such client hints and Cloudflare headers are ignored.
- `Browser.new` checks the size of the user agent before reading it, so an oversized one is rejected in microseconds.

## [3.1.0] — 2026-11-06

A Google Cloud VM no longer passes as a verified Googlebot, and a forged Googlebot can no longer stall requests on reverse DNS.
