 # Changelog
 
+## [0.0.2] - 2025-04-04
+
+Important bugfixes for filtering language and sample subsetting.
+
+- Clarify the implementation status of the filtering mini-lanuage in
+  view/query. Version 0.0.1 contained several data-corrupting bugs,
+  including incorrect missing data handling (#163), incorrect
+  matching on FILTER (#164) and CHROM (#178) columns, and
+  incorrect per-sample filtering in query (#179). These issues
+  have been resolved by raising informative errors on aspects
+  of the query language that are not implemented correctly.
+
+- The filtering mini-language now consists of arbitrary arithmetic
+  expressions on 1-dimensional fields.
+
+- Add support for specifying samples via -s/-S options
+
