### v0.10.0 (unreleased)

#### Upgrade notes

Several breaking changes were made between 0.9 and 0.10, but changes should be straightforward:

* The `lettre_email` crate has been merged into `lettre`. To migrate, replace `lettre_email` with `lettre::builder`
  and make sure to enable the `builder` feature (it's enabled by default).
* `SendableEmail` has been renamed to `Email` and `EmailBuilder::build()` produces it directly. To migrate,
  rename `SendableEmail` to `Email`.
* The `serde-impls` feature has been renamed to `serde`. To migrate, rename the feature.

#### Features

* Add `rustls` support ([29e4829](https://github.com/lettre/lettre/commit/29e4829), [39a0686](https://github.com/lettre/lettre/commit/39a0686))
