v0.2.0

⚠️ Breaking: keep fluent-zero and fluent-zero-build on the same version; generated code now checks this at compile time.

• Public API trimmed: lookup functions, CacheStore, BundleCollection and dependency re-exports (phf, fluent_syntax, FluentError, bundle types) moved behind the hidden __private module. Use t! / t_in!. get_lang() returns Arc<LocaleState>; LocaleState has id() and key().
• Fallible builder: try_generate() returns fluent_zero_build::Error (parse errors with path:line:col, duplicate IDs, missing or invalid fallback locale, denied missing translations, I/O); generate() panics with the same message. crate_path(...) supports renamed dependencies.
• Locales: negotiation with a fallback chain (set_lang("pt-BR") finds pt-PT), configurable fallback_locale, per-call t_in!, generated CATALOG.
• Correctness: charset covers select variants, attributes and terms; quotes in static messages no longer break the build; duplicate IDs are reported with both locations; message attributes via message.attribute keys; deterministic generated output.
• Compile-time checks: literal keys passed to t! / t_in! must exist; generated keys module with one constant per key.
• Diagnostics: set_error_handler / LookupError (or the tracing feature) for missing keys and arguments; translation coverage warnings via missing_translations.
• Options: use_isolating(false) to drop U+2068/U+2069 bidi marks.
• Packaging: MIT LICENSE shipped in both crates, MSRV 1.88, hardened CI, benchmarks and a zero-allocation test.
• Dependency upgrades: arc-swap 1.9. fluent-langneg stays on 0.13 to match fluent-bundle 0.16 (0.14 moved to ICU4X identifiers).

v0.1.5

• Avoid Redundant Rebuilds: fluent-zero-build now only writes the character set file if its content has actually changed, preserving file modification timestamps and preventing unnecessary rebuilds on every Cargo invocation.
• Dependency Upgrades: Upgraded phf and phf_codegen to 0.14.
• CI & Repository Maintenance: Added GitHub Actions CI workflow for cargo fmt and cargo test, .editorconfig, and funding metadata.

v0.1.4

Enterprise Font Subsetting (DAG IPC)

• Hermetic & Cache-Safe: fluent-zero-build now natively leverages Cargo's Inter-Package Communication (IPC) to aggregate character sets across all nested dependencies.
• No More Scraping: Replaces brittle cargo_metadata workspace-walking with a 100% sccache, Bazel, and Nix compatible build pipeline.

⚠️ Migration & Setup: Dependency crates must now declare a globally unique links key in their Cargo.toml. Please see the Enterprise Font Subsetting (DAG IPC) section in the README.md for full instructions and a copy-paste Python subsetter script template.

v0.1.3

New FluentZeroBuilder API for generating charset, allowing easy font subsetting.

v0.1.2

Small, miscellaneous documentation improvements and fixes.

v0.1.1

Hotfix:

• add shields to the README.md
• link to the source code repository and docs.rs documentation from the Cargo.toml metadata.
