Release notes

Sourced from chardet's releases.

7.6.0

Big release: a Cython scoring kernel joins mypyc in compiled wheels, every model retrained on a deduplicated corpus, UTF-7 fixed in both directions, and a guarantee that detect() never returns an encoding that can't decode your complete input.

Performance

• Compiled wheels now score bigram profiles through a small Cython kernel alongside mypyc, and the pair is 4.7x faster than the pure wheel on CPython 3.14. _kernel.py stays plain Python (PyPy and pure wheels run it interpreted, unchanged), and detection output is bit-identical. The kernel declares itself safe without the GIL, so free-threaded CPython scales instead of silently re-enabling the GIL on import: 3.14t runs the whole suite in ~340ms across 8 threads, the fastest configuration measured. Compiled builds now need both hooks: HATCH_BUILD_HOOK_ENABLE_MYPYC=true HATCH_BUILD_HOOK_ENABLE_CUSTOM=true.
• Added support for CPython 3.15, including the free-threaded build. No code changes were needed.

Bug Fixes

• detect() no longer returns an encoding that cannot decode the input it was given (#380, thanks @​yarikoptic). When the whole input has been examined and the winner's only multi-byte evidence is an incomplete trailing sequence, the best candidate that decodes the input completely wins instead. Genuinely truncated data keeps its answer.
• Fixed delimited ASCII data like |NAME,+LAY| misdetecting as UTF-7 (#371 follow-up, thanks @​agreenburg). The whole buffer must now actually decode as UTF-7, and a lone shifted character must land in a plausible script range.
• Signed UTF-7 no longer reads as ASCII: the BOM stage recognizes the four UTF-7 signature prefixes when the rest of the buffer decodes as UTF-7.
• Fixed short apostrophe-heavy English being labeled Scottish Gaelic or Breton: a rare-language label on an input under 128 bytes now needs a 0.03 lead over the best mainstream language (ADR-0005).
• Fixed Hungarian text losing to a Czech reading in confusion rescoring; tied pairs are compared only under language models both encodings have.
• Fixed space-padded text matching a degenerate Serbian model at high confidence; statistical scoring now skips repeated-whitespace bigrams. This also fixes windows-1251 logs misdetecting as windows-1250 (#379).
• Fixed EBCDIC text being invisible to the early pipeline stages, and the last two EBCDIC sibling misdetections.
• Fixed training normalization gaps that starved ISO-8859-16 and the 26 pre-euro encodings at exactly their distinguishing bytes.

Improvements

• Retrained every bigram model on a refreshed, deduplicated corpus with training provenance now recorded per model.
• New ANSI-art model for cp437, trained on 16,621 text-mode art files from 16colo.rs.
• Rare-language arbitration (ADR-0005): low-confidence statistical winners from languages with no documented legacy-encoding population yield to near-tied mainstream candidates.
• Confusion-group resolution is context-aware: per-occurrence votes, word-shape demotions, art-model exemption.
• Statistical dead heats no longer resolve by candidate enumeration order.
• Training pipeline hardening after a cache-loss post-mortem.

7.6.0 (2026-08-14)

Performance:

• Compiled wheels now score bigram profiles through a small Cython kernel alongside mypyc, and the pair is 4.7x faster than the pure wheel on CPython 3.14. _kernel.py stays plain Python (PyPy and pure wheels run it interpreted, unchanged), _kernel.pxd adds C types at build time and ships nothing, and detection output is bit-identical. The kernel declares itself safe without the GIL, so free-threaded CPython scales instead of silently re-enabling the GIL on import: 3.14t runs the whole suite in ~340ms across 8 threads, the fastest configuration measured. Compiled builds now need both hooks::

Bug Fixes:

• Fixed delimited ASCII data like |NAME,+LAY| misdetecting as UTF-7, a follow-up to [#371](https://github.com/chardet/chardet/issues/371) <https://github.com/chardet/chardet/issues/371>. Two new checks: the whole buffer must actually decode as UTF-7 (+| is an illegal shift, so tabular data fails immediately), and a block encoding a single code unit must land in a script range where a lone shifted character plausibly occurs. +LAY decodes to U+2C06, Glagolitic; no genuine lone block in the corpus lands anywhere like it, while em dashes, ellipses, kanji, and accented letters all pass. (Dan Blanchard <https://github.com/dan-blanchard> via Claude)
• Signed UTF-7 no longer reads as ASCII. The BOM stage recognizes the four UTF-7 signature prefixes (+/v8- and friends) when the rest of the buffer decodes as UTF-7 --- the prefix alone is ordinary ASCII (a diff of V8 source paths starts with +/v8). This is a deliberate divergence from WHATWG's browser-security exclusion of UTF-7: chardet already detects the unsigned form, so refusing only the signed one made no sense. (Dan Blanchard <https://github.com/dan-blanchard>_ via Claude)
• detect() no longer returns an encoding that cannot decode the input it was given ([#380](https://github.com/chardet/chardet/issues/380) <https://github.com/chardet/chardet/issues/380>_). When the whole input has been examined and the winner's only multi-byte evidence is an incomplete trailing sequence, the best candidate that decodes the input completely wins instead. Genuinely truncated data keeps its answer: CJK cut mid-character, or input sliced at
