Release Notes: This release fixed a serious recipient callout caching bug. A change that caused Exim to use the real sender when doing recipient callouts was reversed, though a new option to request the altered behaviour was included. There were also a few new features.
Release Notes: A surprisingly large number of minor bugs have been fixed. Support for maildirsize files has been completely rewritten. A limited number of feature enhancements are included.

Exim no longer adds missing Message-ID, Date, and From headers to messages submitted through TCP/IP. The "port" option of the SMTP transport is now expanded. ACLs can now make use of a $received_count variable and a logwrite modifier.
Release Notes: This is a strict bugfix release over 4.24, the most prominent one being the fix of a trivial build error.

The most prominent is probably that the ACL variables $acl_xx are now saved with the message, and can be accessed later in routers, transports, and filters.
