chore(deps)(deps): bump icu from 1.5.0 to 2.1.1

[dependabot]

Bumps icu from 1.5.0 to 2.1.1.

Release notes

Sourced from icu's releases.

ICU4X 2.1.0

The ICU4X Technical Committee is happy to announce ICU4X 2.1, an update to our modular, portable, and secure i18n library.

Important changes since ICU4X 2.0 include:

1. Latest i18n data: This release includes an update to CLDR 48.
2. Calendar improvements: ICU4X is now being used to implement Temporal in V8 and SpiderMonkey. icu_calendar has received many fixes and improvements in service of that, including new experimental arithmetic APIs.
3. Normalizer optimizations: icu_normalizer has received a lot of optimization work, with some more to come. Optimizations made to shared data structures will benefit other components as well.
4. Collation sort keys: It is now possible to use icu_collator to extract the sort key of a given string to amortize the cost of collation operations.

When updating ICU4X crates to 2.1, you may experience issues due to incompatibilities between buggy older crates and newer crates around the alloc feature. In that case, please run cargo update for any crates that show up in the errors.

ICU4X 2.0.0

The ICU4X Technical Committee is happy to announce ICU4X 2.0, a major update to our modular, portable, and secure i18n library.

Important changes since ICU4X 1.5 include:

1. Preference Objects: Instead of directly passing Locale objects to formatters, most constructors now accept "preference bags." These can be derived from locales but also constructed directly with type-safe enums, and they are more efficient.

2. Date, Time, and Time Zone Rewrite: The icu::datetime component underwent a complete rewrite with APIs that improve performance and make it easier to do the right thing. The new icu::time component replaces icu::timezone and handles i18n-focused date, time, and time zone representations.

3. FFI Overhaul: C++ namespaces, improvements to function versioning, and idiomatic improvements in all languages, such as getters/setters, iterators, and constructors.

4. Borrowed variants: More types have separate owned and borrowed variants, which improves performance. This also enables more components to be compiled without an allocator, making some crates fully #[no_std].

5. Compiled data updated: All components ship with the latest versions of CLDR (47.0) and Unicode (16.0).

Thanks to everyone who tried the 2.0 Beta releases. We have used your feedback to improve the 2.0 release.

ICU4X 2.0 Beta 2

This release includes a lot of the remaining changes slated for 2.0. The major difference from 2.0-beta1 is that it fills in FFI for all new APIs except for those in datetime.

This release also brings ICU4X to CLDR 47 Beta 1, ICU 77 RC, and TZDB 2025a.

This release is intended to be a stepping stone to the final 2.0 release: we do not expect major changes after this, except potentially to datetime FFI. Clients are encouraged to update to this to experience a smoother 2.0 upgrade.

This release includes some breaking changes over 2.0 beta 1.

• The datetime crate has continued to evolve, with some API renames, though the shape of the crate is mostly the same.
• icu_timezone has been renamed to icu_time, and has been restructured.
• Users of --no-default-features may find themselves needing to explicitly opt in to an alloc feature for some crates, as ICU4X is gaining the ability to be no-alloc.
• Many std features have been removed from crates that no longer need them.

Please refer to the changelog for a full set of differences.

Changelog

icu 2.2.x

Several crates have had patch releases in the 2.2 stream:

• Components
  • (2.2.1) icu_calendar
    • Fix extended year calculations in Gregorian-like and Coptic-like calendars (unicode-org#7849)
• Utils
  • (0.8.3) yoke
    • Fix soundness of Send/Sync impls on CartableOptionPointer (unicode-org#8029)
    • Update to 2024 edition where possible (unicode-org#7878)

icu4x 2.2

• Components
  • General
    • Use HTTPS links in docs (unicode-org#7212)
    • Update MSRV to 1.86 (unicode-org#7576)
    • Updated to CLDR 48.2 (unicode-org#7792)
    • Replace experimental features with unstable features (unicode-org#7566)
    • Add categories and keywords to Cargo.toml for all components (unicode-org#7737)
  • icu_calendar
    • Add Date::try_new, which replaces Date::try_new_from_codes, and takes typed year/month values. (unicode-org#7773, unicode-org#7764)
    • 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)
    • New Date::try_from_fields API for fully general date construction from various choices of year and month values (unicode-org#7798)
    • New methods: Date::try_from_fields()
    • New types: DateFields, DateFromFieldsOptions, Overflow, MissingFieldsStrategy, DateFromFieldsError
    • New associated method: Calendar::from_fields()
    • New Date arithmetic APIs for adding and subtracting dates (unicode-org#7798, unicode-org#7355, unicode-org#7257)
    • New methods: Date::try_add_with_options, Date::try_added_with_options, Date::try_until_with_options
    • New types: DateDuration, DateAddOptions, DateDifferenceOptions, DateDurationUnit, DateDurationParseError, DateAddError, MismatchedCalendarError
    • New associated items: Calendar::add, Calendar::until, Calendar::DateCompatibilityError

      • New type: Month
      • New method: MonthInfo::to_input()
    • 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#7676, unicode-org#7062, unicode-org#7629, unicode-org#7753, unicode-org#7219, unicode-org#7227)

    • New enum: LeapStatus
    • (Unstable) Integrate with chrono, jiff, and time (unicode-org#7617, unicode-org#7711)
    • New impls: From<chrono::NaiveDate>, From<jiff::civil::Date>, From<time::Date> for Date<Gregorian>
    • Replace Date::day_of_week by Date::weekday (unicode-org#7288)
      • New method: Date::weekday()
