Up to 56afe569 Reading prior state from /home/manishearth/dev/sand/changelog.json # Crates ===================== ## General - Replace `experimental` features with `unstable` features (unicode-org#7566) - Update MSRV to 1.86 (unicode-org#7576) - Add categories and keywords to Cargo.toml for all components (unicode-org#7737) ## calendrical_calculations - Change some functions to `const` (unicode-org#7524) - New `const` APIs: `gregorian::gregorian_from_fixed()`, `gregorian::easter()` - Changed `Location::try_new` from `pub(crate)` to `pub` (unicode-org#7775) - New Methods: `Location::try_new()` - New errors: `LocationOutOfBoundsError` ## demo - Support deep links to the WASM demo (unicode-org#7567) ## ffi - Optimize Date storage by avoiding Arc (unicode-org#7434) - Rename `is_normalized[_up_to]()` to `is_normalized_utf8()` on `DecomposingNormalizer` (unicode-org#7183) ## icu4x-datagen - Add `--ucd-tag` and `--unihan-root` flags (unicode-org#7504) - Improve error messages (unicode-org#7598) - Add `latest-tag` value for tag arguments (unicode-org#7599) ## icu_calendar - Replace `JapaneseExtended` with reexport of `Japanese`, since CLDR no longer includes pre-Meiji eras. (unicode-org#7322) - Use UmmAlQura under the hood for AstronomicalSimulation. (unicode-org#7342) - Clients wishing to use the Reingold simulation are encouraged to write their own implementation of `hijri::Rules` using code from `calendrical_calculations`. - Optimize `Japanese` data storage, making `Japanese` no longer need to persist loaded data. (unicode-org#7323) - Deprecate `AstronomicalSimulation` (use `UmmAlQura` or a custom calendar instead) (unicode-org#7455) - Deprecate `Date::extended_year()` (use `Date::year().extended_year()`) (unicode-org#7289) - Start producing Meiji era only after Meiji 6 (unicode-org#7503) - Add constructors with `Month` for lunisolar calendars (unicode-org#7485) - New methods: `Date::try_new_korean_traditional()`, `Date::try_new_chinese_traditional()`, `Date::try_new_hebrew_v2()` - Reject date strings with invalid calendar annotations (unicode-org#7626) - Expose `LeapStatus` on `MonthInfo` (unicode-org#7667) - New method: `MonthInfo::leap_status()` - New enum: `LeapStatus` - Introduce year/date ranges to all APIs, documented on the APIs themselves. `Date` now has a fundamental range (ISO years between ±999,999), and most constructors enforce a stricter range of ±9999 years for input years.

(unicode-org#7734) - Add `Date::try_from_codes`, which replaces `Date::try_new_from_codes`, and takes typed year/month values. (unicode-org#7764) - New methods: `Date::try_from_codes` (and primarily-internal `Calendar::from_codes2`) - New types: `InputYear`, `DateFromCodesError` - Speed up `until` year and month field handling by 75% on average by optimizing `surpasses` calculation (unicode-org#7745) - Add `Date::try_new`, which replaces `Date::try_new_from_codes`, and takes typed year/month values. (unicode-org#7773) - New methods: `Date::try_new` (and primarily-internal `Calendar::new_date`) - New types: `InputYear`, `DateNewError` - Handle possible Overflow values on individual calendars (unicode-org#7795) ## icu_capi - Expose `Date::is_in_leap_year()` (unicode-org#7518) - Expose `PluralRulesWithRanges` (experimental) over FFI (unicode-org#7481) - Expose a compiled data version of `CaseMapper::titlecase_segment_with_only_case_data()` (unicode-org#7595) - Expose `ZonedDateTimeFormatter::format_same_calendar()` over FFI (unicode-org#7645) - Add FFI type CaseMapLocaleConsts for cheap casemapping from known locale tailorings. (unicode-org#7642) - Expose BCP-47 locale variant APIs over FFI (unicode-org#7519) - New methods: `variants()`, `variant_count()`, `variant_at()`, `has_variant()`, `remove_variant()`, `clear_variants()` on `Locale` ## icu_codepointtrie_builder - Add more ways of specifying code point trie data. (unicode-org#7541) - New variants: `CodePointTrieBuilderData::ByCodePoint`, `CodePointTrieBuilderData::Map` - New trait impl: `Debug for CodePointTrieBuilderData` - (Breaking) Actually make `CodePointTrieBuilder` a builder type. This API has changed significantly, please look at the docs for the new API. (unicode-org#7581) - Optimize by using `umutablecptrie_setRange` (unicode-org#7584) ## icu_collator - Document considerations related to lowering the collation strength from the default (unicode-org#6662) - (Optimization) Avoid tagging Hangul syllable in collation data (unicode-org#7540) ## icu_datetime - Use appropriate date/time/zone glue patterns based on appendItems (unicode-org#7416) - Optimize `Japanese` era storage, cutting down era name size by 20kb. (unicode-org#7323) - Add support for Clock12 and Clock24 hour cycles (unicode-org#7414) - Add AM/PM getters on `FixedCalendarDateTimeNames` (unicode-org#7127) - New methods: `FixedCalendarDateTimeNames::get_am()`, `FixedCalendarDateTimeNames::get_pm()` - Use month number instead of ordinal month in formatting (unicode-org#7574) - Support formatting without era field (unicode-org#7606) - New variant: `YearStyle::NoEra` - Integrate with `chrono`, `jiff`, and `time` (unicode-org#7617) - New impls: Various scaffolding traits on `chrono::NaiveDate`, `jiff::civil::Date`, and `time::Date`, making them formattable. - Allow formatting `Weekday` (unicode-org#7719) - New trait impls: `InSameCalendar` and `ConvertCalendar` on `UtcOffset` and `Weekday` - Don't expose CLDR's Hebrew month numbering during formatting (unicode-org#7728) - Reduce data size by storing leap patterns where possible (unicode-org#7666) ## icu_decimal - Move `CompactDecimalFormatter` (experimental) to this crate (unicode-org#7565) - (Experimental) Consider numbering system in compact formatter (unicode-org#7543) ## icu_experimental/currency - Don't produce empty compact currency data (unicode-org#7494) ## icu_experimental/displaynames - Adds new data markers for display names using attributes for better slicing (unicode-org#7692) ## icu_experimental/transliterator - Fix UB caused in partially-written unwind states by using checked UTF-8 conversion instead of `from_utf8_unchecked` (unicode-org#7781) ## icu_locale_core - Deprecate `LanguagePreferences` field accessors (unicode-org#7401) - Add parsing for `-u-hc-c12` and `-u-hc-c24` (unicode-org#7414) - Add better docs on the relationship between Locale and DataLocale (unicode-org#7382) - Disallow `true` in multi-level preference values (unicode-org#7471) - Match preferences on full value. This removes fallback behavior from e.g. `u-ca-gregory-foobar` to `-u-ca-gregory`. See [CLDR-19229](https://unicode-org.atlassian.net/browse/CLDR-19229). (unicode-org#7477) - Add locale variant mutation APIs (unicode-org#7519) - New methods: `Variants::push()`, `Variants::remove()` ## icu_normalizer - Expose the UTS 46 virama check using UTS 46 data (unicode-org#7507) ## icu_plurals - Handle large-magnitude numbers being converted to PluralOperands (unicode-org#7502) ## icu_properties - Add buffer provider constructors for all property APIs (unicode-org#7384) - New methods: `CodePointMapData::try_new_with_buffer_provider()`, `CodePointSetData::try_new_with_buffer_provider()`, `EmojiSetData::try_new_with_buffer_provider()` - Improve performance of property name lookup (unicode-org#7623) ## icu_provider_source - Allow specifying UCD/Unihan source (unicode-org#7504) - New methods: `SourceDataProvider::with_unihan_for_tag()`, `SourceDataProvider::is_missing_unihan_error()` - Update to CLDR 48.2-BETA0 (unicode-org#7681) - Update tzdb to 2026a (unicode-org#7729) - Adds code to generate the new markers in icu_experimental/displaynames (unicode-org#7692) ## icu_segmenter - Add methods to load LSTM or dictionary data for existing segmenters (unicode-org#7590) - New methods on `LineSegmenter` and `WordSegmenter`: `with_lstm_unstable()`, `with_lstm_with_buffer_provider()`, `with_dictionary_unstable()`, `with_dictionary_with_buffer_provider()` - New mthods on `LineSegmenterBorrowed` and `WordSegmenterBorrowed`: `with_lstm()` and `with_dictionary()` ## icu_time - Make `UtcOffset::try_from_str()`, `try_from_seconds()`, `try_from_utf8()` const (unicode-org#7536) - Fix overflow in `from_epoch_milliseconds_and_utc_offset()` (unicode-org#7604) - Add compiled data constructors for TimeZone (unicode-org#7639) - New methods: `TimeZone::from_iana_id()`, `::from_windows_id()`, `::from_system_id()`. - Reduce unnecessary checks during `ZonedDateTime` parsing.

See #6698 ## Remove `YearInfo: PartialEq` bound (https://github.com/unicode-org/icu4x/pull/7743) There's code that compares whole `YearInfo`s when it should be comparing extended years. ## Make min_months invariant no longer a hard invariant for Chinese/Korean (https://github.com/unicode-org/icu4x/pull/7753) This is one way of resolving (some of?) @robertbastian's concerns from https://github.com/unicode-org/icu4x/pull/7739 ## Change nesting of `atTime` and zone `appendItems` (https://github.com/unicode-org/icu4x/pull/7755) Follow up https://github.com/unicode-org/icu4x/pull/7416 The time zone should be appended to the time, not to the joined `atTime` result: https://unicode-org.atlassian.net/browse/CLDR-19226 ## Use `YearNames::FixedEras` for Japanese (https://github.com/unicode-org/icu4x/pull/7700) I've marked this API breaking because it breaks new-data-old-code. We either wait until 3.0 or introduce a new data marker, that might be worth it for a 26kB size reduction. # Potentially misformatted (double check please!) ===================== - Replace ByteStr with SliceWithIndices and SerdeByteStr (https://github.com/unicode-org/icu4x/pull/7748) - Make some `ZonedDateTime<Iso, UtcOffset>` functions generic in calendar (https://github.com/unicode-org/icu4x/pull/7630) # N/A ===================== - Compartmentalise decimal formatting code (https://github.com/unicode-org/icu4x/pull/7411) -
