I’ve just released the first release candidate for Swiftmailer 4.1.

This new version of Swiftmailer has several new features:

• changed the Decorator Plugin to allow replacements in all headers
• added Swift_Mime_Grammar and Swift_Validate to validate an email address
• modified the autoloader to lazy-initialize Swiftmailer
• removed Swift_Mailer::batchSend()
• added NullTransport
• added new plugins: RedirectingPlugin and ImpersonatePlugin
• added a way to send messages asynchronously (Spool)

You can install this new version as usual:

• by downloading the archive
• or use the PEAR channel
