Minimum Supported Rust Version (MSRV) Policy

We follow these MSRV rules:

• The current MSRV is 1.88.
• MSRV bumps do NOT require a major release and may happen in minor releases.
• The MSRV may be updated when needed, but support for the current stable Rust release and the previous two stable releases (N, N-1, N-2) is always guaranteed.
  • For example, if the current stable version is 1.85, we guarantee support for 1.85, 1.84, and 1.83, so the minimum supported Rust version will be at most 1.83.
• MSRV is bumped only when needed, e.g.:
  • required by dependencies
  • any serious bug is found (including security-related)
  • adopting new stable Rust features
• Every MSRV bump is documented in the release notes when it happens.

Origins

Inspired by Go's fsnotify and Node.js's Chokidar, born out of need for cargo watch, and general frustration at the non-existence of C/Rust cross-platform notify libraries.
