Great Expectations 1.18.2 was published on June 26, 2026, with a narrow fix for Spark Connect compatibility in distinct values metrics. The release removes .rdd usage from Spark metric code, which matters when validation suites run against Spark Connect instead of a classic Spark driver path. It is not marked as a prerelease.

Great Expectations 1.18.1 is a patch release for the open source data validation framework, published on 11 June 2026. The single functional change corrects HTML escaping for regex angle brackets in Data Docs, a rendering bug that could distort validation reports when expectations use pattern syntax containing < or > characters.
