5 September 2023 (LibreSSL 3.7.3)

Fix: The default DSN string was malformed if -dsn was not specified.
Feature: The -results:filename setting has been added to output JSON-formatted information about e-mail delivery.
Feature: Support for user-supplied XOAUTH2 bearer tokens has been added. This has been veified to work with the GMail implementation.
Miscellany: Password encryption can now be used with passwords longer than 255 bytes (E.g. Oauth2 tokens).

26 July 2023 (LibreSSL 3.7.3)

Fix: The -body-64 setting did not work if it preceeded -body-file.
Fix: The -verify option was looking for certificates in a development path by default. The -verify-ca-path has been added to specify the certificate location and is now required when -verify is used.
Feature: The -config setting can read configuration from stdin using -config:-.
Miscellany: First release supported by CMailGUI.
Miscellany: The -secureport setting has been renamed -smtps. The original setting will continue to work in the 0.8.x branch.

19 May 2023 (LibreSSL 3.7.2)

Fix: DKIM domain and selector lengths were reversed. Domains longer than 63 bytes are now supported for DKIM signing.
Feature: E-mail can now be signed using ed25519-sha256 and -dkim-algo can be specified multiple times to allow for multiple signing methods. If not specified, CMail will sign using rsa-sha256 and ed25519-sha256 where suitable keys have been provided.
Feature: Added -tls-ciphers and -tls-protocols options to control TLS cipher and protocol selection. These settings uses LibreSSL presets and validation is currently not performed. These features may change in future releases.
Miscellany: The -dd option now logs timestamps.
Miscellany: MIME types updated.

27 September 2022 (LibreSSL 3.5.3)

Feature: CMail can now DKIM sign e-mail, including signing preconstructed e-mail on delivery.
Feature: Added a -return-path option to set the envelope address.
Feature: CMail can now use AUTH OAUTHBEARER if the user provides an access token. Support is activated using the -oauth option. The password in -host must contain the OAuth token.
Notice: CMail will no longer attempt to send e-mails if authentication fails.
Miscellany: CMail will now accept 25x status on e-mail completion. Addresses an issue reported by a user, but further details were not provided when requested. The RFC states in the description that a server will return 250 on success, so technically the server is sending the wrong status code, but 2xx is a 'success' code nonetheless.
Miscellany: Minor MIME layout changes.

20 May 2022 (LibreSSL 3.5.3)

Fix: Data corruption when sending pre-constructed messages (x86 only).
Miscellany: Changed MIME encapsulation for simple messages to avoid them showing as having attachments (client-specific behaviour).

3 January 2022 (LibreSSL 3.4.2)

Fix: Possible crash or authentication failure using CRAM-MD5 authentication.
Feature: Certificates can now be verified using the -verify setting.
Miscellany: Display names in headers such as To and Cc no longer default to the e-mail address when a value isn’t provided. This was done in the past as some mail filters eroneously associated the lack of a display name with spam. CMail now includes only the e-mail address.

30 December 2020 (LibreSSL 3.2.3)

Fix: Possible timeout when sending e-mail without TLS. Observed in an unreleased FreeBSD build. Windows builds may also be affected.
Documentation: New online usage documentation layout.
Miscellany: Message recommending the use of -starttls instead of -secureport has been removed as this isn’t an option for some users.

17 July 2020 (LibreSSL 3.1.3)

Documentation: Fix incorrect encoding of documentation.

12 July 2020 (LibreSSL 3.1.3)

Feature: Improved code page support.
Feature: Automatic conversion to UTF-8 for message bodies, custom headers and from, to, cc and reply-to display names.
Miscellany: Removed -charset, now specified with -body-file setting.
Miscellany: The -smtp-transparency option has been renamed -dotstuff.
Miscellany: OpenSSL replaced with LibreSSL.

Fix: Body input defaulted to file input, not direct input as intended.

5 September 2023
