+------------------------------------------------------------------------
+
+### Miscellaneous
+
+* Bumped the CEL interpreter (`cel` -> 0.13.0). This could theoretically be a breaking change as the new version of the parser is more compliant with the CEL standard and could reject some existing queries. In practice, this is a quality-of-life improvement by rejecting buggy queries.
+* Bumped the YAML parser (`serde-saphyr` -> 0.0.22).
