v1.0.2

Release date: May 14, 2026

This release fixes a bug where a query could return incorrect rows when all of the following were true:

• the table uses merge mode (merge_mode);
• the range result cache is enabled;
• the query filters the time index column with OR (e.g. WHERE ts = a OR ts = b).

In this case the cache could reuse a previous query's result and return rows that should have been filtered out. This is now fixed. We recommend users on v1.0.0 and v1.0.1 upgrade to v1.0.2. (#8105)
