 title: Building matrix-rust-sdk-crypto-wasm against the latest matrix-sdk Rust is failing
 ---
-See https://github.com/{{env.GITHUB_REPOSITORY}}/actions/runs/{{env.GITHUB_RUN_ID}}
+Something changed in
+[matrix-rust-sdk](https://github.com/matrix-org/matrix-rust-sdk)'s crypto crate
+that will break the build of this repo (matrix-rust-sdk-crypto-wasm) when we
+update to it.
 
-Latest failure: {{ date | date('dddd, YYYY-MM-DD HH:mm Z') }}
+See the crypto crate's
+[CHANGELOG](https://github.com/matrix-org/matrix-rust-sdk/blob/main/crates/matrix-sdk-crypto/CHANGELOG.md)
+for possible hints about what changed and how to fix it.
