- Issues
- Remove Window Functions Old Analyzer Support
- Fix an empty quoted CSV/JSON value read as number 0 by a `Variant` numeric alternative
- CSV/JSONEachRow input: an empty string for `Variant(String, Int64)` is parsed as `Int64 0`, so a CSV/JSON export/import round trip changes `''` to `0`
- `MATERIALIZE COLUMN` of a column added by `ADD COLUMN` overwrites values set by a lightweight `UPDATE` with the column's `DEFAULT`
- Two v1 patch parts that both update an `ADD COLUMN` column make reads, merges and `APPLY PATCHES` fail with `NOT_FOUND_COLUMN_IN_BLOCK`; 26.7 tables break after upgrading to 26.8+ (regression)
- Do not let the request body extend the query of a custom HTTP handler
- Read all statistics of a data part at once
- Parquet format of data parts in MergeTree tables
- Call `addBatchSinglePlace` once per long array in `arrayReduce` and `-Array`
- Stop the distroless entrypoint when the requested user setup cannot be applied
