Thought: I'm happy that our splitting out this stuff from the icu_calendar crate helps organize the changelog better.

- Deprecate `VariantOffsetCalculator` (unicode-org#6905)
- Deprecate time zone variant APIs (unicode-org#6754)
- Move `TimeZoneVariant` to provider module (unicode-org#6822)
- Treat `Etc/GMT+x` as a raw offset, improve formatting (unicode-org#7055)
- Store offset periods as UTC (unicode-org#6746)
- Align rearguard metazone variant overrides with CLDR (unicode-org#6896)
- Use accurate `ZoneNameTimestamps` (unicode-org#6942)
- Optimize DST offsets using a lookup table (unicode-org#6765)
- Model `America/Punta_Arenas` as permanent DST in Chile metazone (unicode-org#6772)
- Data model and providers
- ...
- `icu_provider_baked`
- Expose const structs in baked data (unicode-org#6652)
- `icu_provider`
- Allow building in no-alloc mode (unicode-org#6997)
- `icu4x-datagen`
- Don't require sources to be set in `icu4x-datagen` (unicode-org#6892)
- `icu_provider_source`
- Update to CLDR 48 CLDR (unicode-org#6793, #6989, #7046)

- Handle locales without `territories.json`, locales with inconsistent patterns (unicode-org#6709)
- FFI
- `icu_capi`
- All C++ enums now default to a valid value; which is the `Default` impl where there is one, and some semi-logical value otherwise. This has changed defaults in some cases and may cause a behavioral change for people relying on C++ default constructors. (unicode-org#6692)
- Wasm code now uses the stable standard `wasm-c-abi=spec` (unicode-org#6679)
