 * export v1: Added a deprecation warning for this command. [#1265][] (@victorlin)
 * export v1: The recently introduced flag `--metadata-id-columns` did not work properly due to the same `export v2` bug that was fixed in this release. Instead of fixing it in `export v1`, drop the broken feature since this command is no longer being maintained. [#1265][] (@victorlin)
 * filter: Expose internal Pandas errors from `--query` which may be useful to users. [#1267][] (@victorlin)
+* filter: Previously, `--query` would fail when numerical comparisons were used on columns with missing values. This has been fixed. [#1269][] (@victorlin)
