| 21 | +# Apache IoTDB 1.3.5 |
| 22 | + |
| 23 | +## Improvements |
| 24 | +- Storage Module: Optimize user password encryption by changing the algorithm to SHA-256 |
| 25 | +- ... |
| 26 | + |
| 27 | +## Bugs |
| 28 | +- Fixed the array out-of-bounds exception in cross-Region aggregate query with align by device |
| 29 | +- Fixed the error in aggregate queries with `order by time + align by device` for single or multiple devices spanning across Regions |
| 30 | +- Fixed the "out of memory" error in query with large TEXT objects + align by device + order by time |
| 31 | +- Fixed the issue where the last query with where time > X and time < X was not applied to partitioned table fetching, resulting in failure to hit PartitionCache |
| 32 | +- Fixed the error in using change_point function + align by device when single device data spans multiple Regions |
| 33 | +- Fixed the OOM (Out of Memory) issue caused by the asynchronous submission queue of pipeTransferFile |
| 34 | +- Fixed the memory leak issue in pipe password detection |
| 35 | +- For the pipe receiver and during Load, change the behavior of'clear schema cache' to 'update last cache' |
| 36 | +- Optimize the loading speed of TsFile when there are a large number of measuring points and the mods file contains deletions of a large number of measuring points |
| 37 | +- ... |

| 39 | +# Apache IoTDB 1.3.4-1 |
| 40 | + |
| 41 | +This is a bug-fix version of 1.3.4 |
| 42 | + |
| 43 | +- Fix the bug that will remove the data partition table by mistake in case of us/ns time precision and using ttl |
| 44 | + |
| 45 | +# Apache IoTDB 1.3.4 |
| 46 | + |
| 47 | +## Features & Improvements |
| 48 | + |
| 49 | +- Data Query: Users can now control the loading of JAR packages via URI for UDF, PipePlugin, Trigger, and AINode through configuration items. |
| 50 | +- Data Query: Added monitoring for TimeIndex cached during the merge process. |
| 51 | +- System Management: Expanded UDF functions with the addition of the pattern_match function for pattern matching. |
| 52 | +- System Management:The Python session SDK now includes a parameter for connection timeout. |
| 53 | +- System Management:Introduced authorization for cluster management-related operations. |
| 54 | +- System Management:ConfigNode/DataNode now supports scaling down using SQL. |
| 55 | +- System Management:ConfigNode automatically cleans up partition information exceeding the TTL (cleans up every 2 hours). |
| 56 | +- Data Synchronization: Supports specifying authorization information for the receiver on the sender's end. |
| 57 | +- Ecosystem Integration: Supports Kubernetes Operator. |
| 58 | +- Scripts and Tools: The import-data/export-data scripts have been expanded to support new data types (strings, large binary objects, dates, timestamps). |
| 59 | +- Scripts and Tools:The import-data/export-data scripts have been iterated to support importing and exporting data in three formats: TsFile, CSV, and SQL. |
