Release 2.4.0 comprises:
- Better handling of iso-2022-jp messages
- A new configuration option to handle non-standard Applemail multipart messages where the plain text alternative is empty (applemail_mimehack)
- Use the system libpcre if available. Shipped libpcre updated to upstream version 8.43
- New configure option to compile against a system libtrio (it can't be detected automatically)
- Security fix: An empty Content-Tranfer-Encoding header would result in an unitialized variable being used
to output an unknown encoding warning message. Hypermail now skips this header if it's empty. - Minor bug fixes
Please refer to the Changelog file for detailed changes.
If you're upgrading from version 2.3.x to 2.4.0 please note the following changes:
- The configuration directive "htmlmessage_deleted" has been renamed "htmlmessage_deleted_spam".
- The "deleted" configuration directive has been deprecated in favor of "annotated". However, for backwards compatibility with legacy archives, it will continue to be honored.
Many thanks to @bshannon for his patience and multiple contributions for this release.
