(#816) +- [Java] Added `Tablet.serializedSize()` for exact serialized-size calculation and pre-allocation of serialization buffers. (#824) + +## Improvements + +- [C++] Improved read and write throughput with batch codec APIs, single-pass TsBlock decoding, AVX2/NEON SIMD paths, chunk-level parallel reads, and column-parallel writes. (#823) +- [C++] Optimized timeseries metadata loading by eliminating repeated index traversal and I/O, and accelerated exact TAG lookups for single-TAG tables with direct B-tree lookup. (#815) +- [Java] Optimized timeseries metadata reads by reusing device metadata offsets and reduced redundant metadata-index work. (#840) + +## Bug Fixes + +- [Java/C++] Fixed cross-language compatibility for FLOAT and DOUBLE data encoded with TS_2DIFF, including overflow-page handling and time-decoder selection. (#796) +- [C++] Fixed writer flush-offset handling for multi-gigabyte TsFile files, with tree-model and table-model regression coverage beyond 4 GB. (#839) +- [C++/Python] Fixed crashes and ambiguous device paths involving null TAG values. Python now exposes structured `SeriesPath` values and uses `\N` as the unambiguous null-TAG path marker. (#848) +- [C++] Fixed aligned table null handling, null-TAG metadata-cache collisions, and memory leaks in reader teardown paths. (#823) +- [Java] Fixed table-size accounting when writing metadata for the first table.
