Release highlights

This release focuses on bug fixes and includes changes relating to out-of-order ingestion, InfluxDB line protocol, backups, and filesystem fixes. These fixes enhance the reliability of the system through error prevention and improved stability.

What we fixed

• ILP: check for buffer overflow on writer queue (#1365)
• ILP: fix various edge cases, behaviour of type parsers tcp/udp is closer, allow empty field value as null, support other types (#1312)
• O3: fix wrong timestamp when first o3 row cancelled (#1348)
• O3: fixed o3 crash from ILP usage (#1335)
• SQL: include configuration files and tab index in backups (#1333)
• SQL: ignored LATEST BY column filter if it is indexed (#1327)
• SQL: cast long to GeoHash implementation (#1319)
• SQL: fix lt join for equal timestamps (#1321)
• CORE: we no longer map files to the length of file from the filesystem, we map them to the size received through a transaction "message"
• CORE: we were silently mapping files to filesystem length rather than the required size. We now always map to the required size and report when this is not possible
• CORE: the structure of the "index" column for variable-size columns has changed. It contains N + 1 entries with the last entry being the size of the variable-length column
• CORE: truncated column files to OS page size to avoid undefined behaviour on pages used by readers
• CORE: fixed an issue with truncating symbol.d column on Windows where the order of closing files was incorrect

What is new

• SQL: base64 function to encode binary data (#1355)
