- #330: Improved feedback from failing CLI commands
- #327: Implement toString() for Mailer instances for debugging purposes

#### About the migration ####

Updating to Java8/Jakarta 2.0.1 posed a challenge as the 3rd party S/MIME library https://github.com/markenwerk/java-utils-mail-smime has been abandoned/archived while developing Simple Java Mail. Furthermore, it was still under LGPL3 license while everything else is ApacheV2.

Thankfully, I obtained permissions from the maintainers -as well as original developers from decades ago on SourceForge- to take both java-utils-mail-smime and java-utils-mail-dkim under my wings at Simple Java Mail and change the licensing model! You can now post issues and pull requests here:
- https://github.com/simple-java-mail/java-utils-mail-smime
- https://github.com/simple-java-mail/java-utils-mail-dkim

After almost two years of development the next major release 6.0.0 is finally here! And what a doozy it is, with the following major new features:

The core library is now even smaller compared to the 5.x.x series going from 183kb to 134kb!

- major performance improvement with [advanced batch processing](https://github.com/bbottema/simple-java-mail/issues/214) including support for mail server clusters.
- You can now replace the final sending of emails with [your own logic](https://github.com/bbottema/simple-java-mail/issues/121), using a 3rd party service of your choice.
- 6.0.0 also includes support for [S/MIME signed and encrypted emails](https://github.com/bbottema/simple-java-mail/issues/187)!
- All 3rd party dependencies have been made optional by splitting up Simple Java Mail into easy to use [modules](https://github.com/bbottema/simple-java-mail/issues/183).
- You can now monitor and [handle async processing](https://github.com/bbottema/simple-java-mail/issues/148) using Futures.

- #107 You can now easily forward or reply to emails!

Maintenance updates

Complete JavaDoc overhaul. Navigating the JavaDoc should be much more consistent now (builder API being the single *public* source of truth).

- #122 The email-rfc2822-validator library has been made a proper Maven dependency (not packaged along anymore)
- #120 The DKIM library has been made an optional proper Maven dependency (not packaged along anymore)

to true (https://javaee.github.io/javamail/docs/api/com/sun/mail/smtp/package-summary.html)

Bugfixes
- #110 Trusted hosts should be space-delimited
- #109 Email headers should be allowed to be empty (now conversion errors can occur as well)
- #103 Converting to MimeMessage results in an invalid Content-Disposition for attachments


v4.4.5 (2-September-2017)

- #101 API backwards compatibility update, reinstate old addRecipient API as deprecated (sorry for removing it abruptly)


v4.4.4 (21-August-2017)

API usability release. *This relase streamlined the recipient setters, breaking backwards compatibility (but straightforward to fix)*

- #95 Feature: Add support native API for setting Return-Receipt-To header
- #93 Feature: Add support native API for setting Disposition-Notification-To header
- #91 *Feature: Add support for parsing preformatted email addresses that include both name and address*
- #94 Bugfix: A single EmailBuilder would build emails that all share the same collections for recipients, attachments and embedded images
- #98 Bugfix: Subject and body content should be optional

v4.3.0 (12-August-2017)

Security and timeout release.

This version safeguards against SMTP injection attack from external values entering the library through *Email* instance. Also, this release
introduces default/configurable timeouts for connecting, reading and writing when sending an email.

- #89 Support multiple delimited recipient addresses sharing the same TO/CC/BCC name
- #88 Safeguard subject property (and others) against SMTP CRLF injection attacks
- #85 Apply configurable timeouts when sending emails
- #83 Parse INLINE attachments without ID as regular attachments when converting (mostly applicable to Apple emails)


v4.2.3 (21-May-2017)

- #79: Enhancement: define custom message ID on the Email object
- #74: v4.2.3-java-6-release: A java6 version with limited capabilities:
    I've released a customised java6 release with a customised outlook-message-parser 1.1.16-java6-release. This is the last java6 release I will do,
     as it is simply too much manual labor to create a limited second edition.

    For this edition, I've removed the JDK7 Phaser completely which has the following consequences:

    - If authenticated proxy is used, the bridging proxy server will not be shut down automatically (and might not run the second time)
    - If mails are sent in async mode, the connection pool will not be shut down anymore by itself

    This means your server/application might not stop properly due to lingering processes. To be completely safe, only send emails in sync mode (used by default) and don't use authenticated proxy config.


v4.2.2 (10-May-2017)

- #73: Patch: fix for sending emails in async mode, which makes sure the connection pool is always closed when the last *known* email has been sent. Without
this fix, the connection pool keeps any parent process running (main thread or Tomcat for example) until a hard kill.


v4.2.1 (12-Feb-2017)

Patch: streamlined convenience methods for adding recipients.


v4.2.0 (12-Feb-2017)

Major feature: Using the EmailConverter you can now convert between Outlook .msg, EML, MimeMessage and Email!

- #66: Feature: convert email to EML
- #65: Feature: read outlook messages from .msg file
- #64: Feature: Added support for logging-only mode that skips the actual sending of emails
- #63: Feature: Already including in previous patch update: Spring support (read properties from Spring context)
- #69: Enhancement: Expanded EmailBuilder API to inlude more options for setting (multiple) recipients
- #70: Enhancement: Most public API now have defensive null-checks for required fields (Fail Fast support)
- #68: Bugfix: Name should be required for embedded images (added safeguards)
- #67: Bugfix: Error when name was omitted for attachment
- minor: added methods on AttachmentResource that reads back the content as (encoded) String
- other: internal testing is now done using Wiser SMTP test server for testing live sending emails

Note: Starting this release, there will always be a Java6 compatible release as well versioned: "x.y.z-java6-release"


v4.1.3 (28-Jan-2017)

- #61: Feature: Add support for providing your own Properties object
- #63: Feature: Spring support (read properties from Spring context)
- #58: Bugfix: Add support for non-English attachment and embedded image names
- #62: Bugfix: Empty properties loaded from config should be considered null

NOTE: ConfigLoader moved from /internal/util to /util
