mail-parser 0.10.0
2+
================================
3+
- Perfect hashing using `hashify` crate rather than static `gperf` generated code.
4+
- Added `DkimSignature`, `ArcAuthenticationResults`, `ArcMessageSignature` and `ArcSeal` headers.
5+
- `HeaderName` is non-exhaustive.
6+
- Parse obsolete timezones (#95).
7+
- Fix: Folding ws between "Content-Type:" and "plain/text" leads to empty header (#96).
8+
- Fix: Multiline quoted continuations (closes #92).
9+
- Fix: Deserialize (#93).
10+
- Retain mbox IO errors (#91).
11+
- Hide concrete type behind impl type (#94).
12+
- Removed `ludicrous` feature, the Rust compiler is smart enough to optimize array lookups.
13+
114
mail-parser 0.9.4
215
================================
316
- Flexible parsing of charset names (#85).
