v0.10.0 (2022-06-29)

Upgrade notes

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

• MSRV is now 1.56.0
• The lettre_email crate has been merged into lettre. To migrate, replace lettre_email with lettre::message 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 tokio 1 support
• Add rustls support
• Add async-std support. NOTE: native-tls isn't supported when using async-std for the smtp transport.
• Allow enabling multiple SMTP authentication mechanisms
• Allow providing a custom message id
• Allow sending raw emails

Breaking Changes

• Merge lettre_email into lettre
• Merge Email and SendableEmail into lettre::message::Email
• SmtpTransport is now an high level SMTP client. It provides connection pooling and shortcuts for building clients using commonly desired values
• Refactor TlsParameters implementation to not expose the internal TLS library
• FileTransport writes emails into .eml instead of .json
• When the hostname feature is disabled or hostname cannot be fetched, 127.0.0.1 is used instead of localhost as EHLO parameter (for better RFC compliance and mail server compatibility)
• The sendmail and file transports aren't enabled by default anymore.
• The new method of ClientId is deprecated
• Rename serde-impls feature to serde
• The SendmailTransport now uses the sendmail command in current PATH by default instead of /usr/bin/sendmail.

Bug Fixes

• Fix argument injection in SendmailTransport (see RUSTSEC-2020-0069)
• Correctly encode header values containing non-ASCII characters
• Timeout bug causing infinite hang
• Fix doc tests in website
• Fix docs for domain field

Misc

• Improve documentation, examples and tests
• Replace line-wrap, email, bufstream with our own implementations
• Remove bytes
• Remove time
• Remove fast_chemail
• Update base64 to 0.13
• Update hostname to 0.3
