# serde release history: 1.0.229 and the long pauses

Source page: https://dev-news.anonyfox.com/serde/

Every serde release since January 2024 from crates.io on one timeline, the gaps between them, and why the version number has only ever moved in its last position since 2017.

## Where it stands (2026-10-24)

serde 1.0.229 went up on crates.io on 18 July 2026, 294 days after 1.0.228. The release note is one line: Update to syn 3.

The pause before that one ran 188 days and ended with 1.0.220 in September 2025, which moved the traits into a new serde_core crate so data formats can build without waiting for serde_derive. serde has been on 1.0 since 20 April 2017. Nine and a half years later the version number has still only moved in its last position.
