Updates tantivy from 0.26.2 to 0.27.0

Changelog

Sourced from tantivy's changelog.

Tantivy 0.27.0

Breaking change

• MSRV is now 1.88.
• .set_fast(..) now takes a &str. The same behavior as .set_fast(None) can be obtained with .set_fast(tantivy::tokenizer::RAW_TOKENIZER_NAME). #3020 #3029(@​fulmicoton @​trinity-1686a)
• Added the FieldType::TieBreaker variant; exhaustive matches on FieldType need a new arm.
• Segment plugins add Custom variants to FieldType, Type, OwnedValue, ReferenceValueLeaf and SegmentComponent, and new TantivyError variants. SegmentComponent is no longer Copy, SegmentSerializer is removed and IndexMerger::write now takes a &Segment #2993(@​rebasedming)
• IndexSettings has a new public sort_by_field field, and ColumnarWriter::serialize / FastFieldsWriter::serialize take an optional doc id mapping #2959(@​rebasedming)
• Directory writers only need terminate(), not flush(). RamDirectory::deep_clone is removed #3095(@​PSeitz)
• BooleanWeight::new is removed; use BooleanWeight::with_minimum_number_should_match #3071(@​fulmicoton)
• SumAggregation has a new none_if_no_match field #2878(@​mdashti)
• IntermediateTermBucketResult::entries() returns a slice instead of a hash map, and intermediate aggregation results no longer implement PartialEq #3040(@​PSeitz)
• Per-segment aggregation request data types (*AggReqData) and columnar::ColumnBlockAccessor are no longer public #3110 #3066(@​fulmicoton)
• tantivy-sstable: BlockReader::from_multiple_blocks and DeltaReader::from_multiple_blocks take the first term ordinal of each block #3030(@​flow3d)
• CompactDoc::node_data is no longer public #3175(@​fulmicoton-dd)

Bugfixes

• Aggregation
  • Fix range and histogram aggregations counting a document several times when several values of a multivalued field fall into the same bucket #3150(@​PSeitz)
  • Fix terms aggregation on numeric values not merging equal keys across segments with different column types (e.g. u64 and i64 in a JSON field) #3051(@​fulmicoton)
  • Fix wrong sub-aggregation results when the terms aggregation missing value also exists as a real term #3163(@​PSeitz)
  • Fix panic in terms aggregation on text fields when missing is used with include/exclude #2907(@​barbarj)
  • Composite aggregation now always returns after_key on a non-empty page, like Elasticsearch #2910(@​Abdul-Andha)
  • Use upstream datasketches for cardinality aggregation, fixing sketch LIST serialization, and switch to HLL8 #2936(@​fulmicoton)
  • Fix possible out-of-bounds write in terms aggregation on corrupt index files #3182(@​fulmicoton-dd)
• Query Parser
  • Fix exponential parse time for deeply nested queries #2905(@​wallies)
  • Fix panic on *^2 and missing boost after a regex (foo:/bar/^2) #2960(@​Darkheir)
  • Fix panics and an endless loop on malformed input #3099(@​PSeitz)
• Fix DisjunctionMaxQuery and other non-summing score combiners being scored as a sum with TopDocs #3022(@​marcbachmann)
• Fix range queries with fractional bounds on integer columns (>= 1.5 no longer matches 1) #3074(@​fulmicoton)
• Fix Streamer::term_ord() returning wrong ordinals when an automaton prunes dictionary blocks #3030(@​flow3d)
• Fix FacetCollector returning a facet from an unrelated branch #2867(@​majiayu000)
• Fix dates outside the i64 nanosecond range wrapping to a wrong date. Dynamic JSON fields index them as strings, typed date fields return an error. Add DateTime::try_from_utc #3156(@​Darkheir)
• Fix overflow in the blockwise linear codec on large jumps #2971(@​trinity-1686a)
• Return an error instead of truncating when a merged str/bytes dictionary exceeds 4GB #3169(@​nadav-govari)
• Fix SegmentReader ignoring I/O errors when opening the positions file #2931(@​JinheLin)
• Replace unmaintained rust-stemmers with frostem, fixing a panic on some Greek words #3028(@​Xuanwo)
• Fix unsound unsafe code in StrColumn::ord_to_str, Term::get_json_path, the doc store and MemoryArena #3175 #3176(@​fulmicoton-dd)

Features/Improvements

• Add generated tie-breaker fast fields via SchemaBuilder::add_tie_breaker_field. Values are consecutive within a segment, start at a random offset, and are preserved across merges. #3104 #3143 #3158(@​PSeitz @​Mallets)
• Calculated fields (experimental, jitexpr feature)
  • Add the jitexpr crate, a Cranelift-based JIT expression compiler with arithmetic, comparison, boolean, null, math, string and regex functions #3078 #3083 #3090 #3107 #3109(@​fulmicoton @​fulmicoton-dd)
  • Add JitExprPredicate to filter documents with a jitexpr expression over fast fields #3081 #3129(@​fulmicoton)
  • Add JitExprValueSourceProvider to use calculated fields in aggregations #3162 #3166(@​fulmicoton)
• Aggregation
  • Add multi-terms aggregation #2984(@​trinity-1686a)
  • Add ValueSource abstraction to aggregate on computed values, registered via AggregationCollector::with_value_sources #3112 #3147 #3160 #3171(@​fulmicoton)

Updates kreuzberg from 4.10.3 to 4.10.4

Release notes

Sourced from kreuzberg's releases.

v4.10.4

[4.10.4] - 2026-09-21

Patch release: CLI acceleration and output-formatting fixes, a dependency refresh, and a TLS advisory bump.

Fixed

• CLI release binaries honour ORT_DYLIB_PATH. The CLI statically linked its bundled CPU ONNX Runtime, so --acceleration cuda failed with "CUDA execution provider requested but not available" even when ORT_DYLIB_PATH pointed at a GPU-enabled runtime. Release artifacts now load ONNX Runtime dynamically and ship a CPU fallback next to the binary. (#8)
• Markdown formatting is no longer stripped from DOCX, EPUB and CSV output. (#5)
• kreuzberg-tesseract releases the native text array when UTF-8 conversion fails, closing an error-path leak. (#7)

Security

• rustls bumped past RUSTSEC-2026-0285. TLS 1.3 handshake messages were accepted across encryption-level boundaries; fixed in 0.23.45.

Changed

• Dependency refresh: liter-llm 1.19 → 2.0.3, tree-sitter-language-pack 1.16.1 → 1.20.0, html-to-markdown-rs 3.12.0 → 3.14.3, and in-range bumps to reqwest, toml, encoding_rs, mail-parser, rmcp and cc.
• Breaking dependency bumps: cfb 0.15, comrak 0.55, lzma-rust2 0.21, dirs 7, lopdf 0.45, jsonschema 0.56, bindgen 0.73.
• The Node package builds with pnpm 12 (two-document lockfile).
• Internal: shell sources are formatted by poly, and the script test suite gains Bats and Pester coverage.

Fixed

• FreeBSD-aarch64: Fix gpregs and fpregs (#5603)

Changed

• AIX: Restore 'c_ulong' as the type of 'statvfs.f_fsid'. (#5616)
• Android: Make prop_info an extern type (#5561)

• FreeBSD: Add back NOTE_PCTRLMASK with a deprecation warning (#5600)

0.2.190

There is now a single config for enabling 64-bit time_t: libc_unstable_time64. This can be set unconditionally; it opts in to 64-bit time_t on the following platforms that use 32-bit by default:

• 32-bit Linux-GNU
• 32-bit Linux-uClibc
• 32-bit Linux-musl. Note that setting this flag also enables some other changes that happend in musl v1.2.
• 32-bit Windows-GNU
• ESP-IDF (all targets with this environment are 32-bit)

Most other 32-bit platforms are either already using 64-bit time_t, or are considered legacy and will not be gaining support from their upstream maintainers.

You can enable this using RUSTFLAGS:

RUSTFLAGS='--cfg=libc_unstable_time64' cargo ...

Note that there may still be some changes to features gated by this config option, hence "unstable"
