I'm trying to get ready to release Email::Simple 2.000. It's going to be a great release, I think. I'm not trying to do the crazy "not-backwards-compatible changes at major version number!" thing. Instead, I'm trying to document and standardize more of the interface. My mantra for the 2.x series of Email::Simple is "better interface standardization." I want it to do roughly the same amount of stuff, with roughly the same performance. I just want it to be clearer how one can subclass Email::Simple, and I want to refactor, document, and improve the usability of the core features of Email::Simple. (This will probably include a rewrite of the Email::Simple<->Data::Message relationship.)

Here's a summary of things I checked in last night:

• better documentation for the Email::Simple::Header object
• provide a means to request a different header class
• public interface for header folding
• documented how options are passed to Email::Simple constructor
• add options to as_string, namely options to alter header folding
• add methods that return default values of various options
• some performance improvements

These changes are mostly here to make it easier to subclass Email::Simple's behavior. In almost every case, I want the answer to "how do I change Email::Simple's" behavior to be "subclass" or (later) "use a plugin." Since some features are really very fundamental core features, though, they seemed like a good place to demonstrate my intentions.

It's in Subversion now, and I'm going to release this as a _x release, soon. Let us know if you have thoughts on these plans or changes either at the PEP mailing list or right here.
