+description: Version 3.3.4.8 Notes
+slug: /release-history/release-notes/3.3.4.8
+---
+## New Features
+1. feat: Interp function supports the fill(near) mode, supports returning the timestamp where the original data is located, and supports finding interpolations within a specified range.
+
+## Optimizations
+1. enh: improve the query performance of TSBS.
+2. enh: support alter multiple tag values of a single child table at the same time.
+3. enh: optimize the error code of the status window.
+4. enh: reduce resource consumption in the force window close mode of stream computing.
+5. enh: remove the restriction that window query must include aggregate functions.
+
+## Fixed issues
+1. fix: use websocket in node.js example of explorer
+2. fix: the problem that WAL is not distributed to multiple level-0 mount points.
+3. fix: abnormal exit of stream computing may lead to a deadlock.
+4. fix(taosX): fix drop table unexpected error when point set enable=0 in opc csv
+5. fix: failed to read WAL file when alter WAL_level from 0 to 2.
+6. fix: deadlock when create snode.
+7. fix: The race condition during replica snapshot synchronization.
+8. fix: the performance degradation of the percentile function after upgrading to 3.3.4.3.
+9. fix: the info of dataDir in ins_dnode_variables is incomplete.
+10. fix: WHERE condition not work in statements with INTERP function
+11. fix: taosd restart failed while use force window close mode in stream computing.
+12. Fix: SQL statements containing “GROUP BY constants” will report “Executor internal error”.
+13. fix: fix OPC-DA connection incorrect NOCONFIG error
+14. fix: in force_window_close mode, the stream computing fails to generate the sub-table names according to the specified rules.
+15. fix: 'schema is old' occurring in schemaless write mode under specific scenarios. https://github.com/taosdata/TDengine/issues/28846
+16. fix: taosX sync with subscription may lost messages in websocket
+17. fix: incorrect sub-table count when filtering by tags (which may cause taosdump crash).
+18. fix: restart a single dnode when RPC compression is enabled may lead to an abnormal cluster state.
+19. fix: unexpected Grafana alerting with CASE WHEN
+20. fix: taosd may crash when performing UNION queries frequently.
+21. fix: subscribe with enable.auto.commit=false not work as expected
