+All notable changes to this project will be documented in this file.
+This project adheres to [Semantic Versioning](http://semver.org/).
+
+## [2.0.0] - 2015-09-02
+
+- Mailer has been removed. It has been replaced by Dialer and Sender.
+- `File` type and the `CreateFile` and `OpenFile` functions have been removed.
+- `Message.Attach` and `Message.Embed` have a new signature.
+- `Message.GetBodyWriter` has been removed. Use `Message.AddAlternativeWriter`
+instead.
+- `Message.Export` has been removed. `Message.WriteTo` can be used instead.
+- `Message.DelHeader` has been removed.
+- The `Bcc` header field is no longer sent. It is far more simpler and
+efficient: the same message is sent to all recipients instead of sending a
+different email to each Bcc address.
+- LoginAuth has been removed. `NewPlainDialer` now implements the LOGIN
+authentication mechanism when needed.
+- Go 1.2 is now required instead of Go 1.3. No external dependency are used when
+using Go 1.5.

+Thank you for contributing to Gomail! Here are a few guidelines:
+
+## Bugs
+
+If you think you found a bug, create an issue and supply the minimum amount
+of code triggering the bug so it can be reproduced.
+
+
+## Fixing a bug
+
+If you want to fix a bug, you can send a pull request. It should contains a
+new test or update an existing one to cover that bug.
+
+
+## New feature proposal
+
+If you think Gomail lacks a feature, you can open an issue or send a pull
+request. I want to keep Gomail code and API as simple as possible so please
+describe your needs so we can discuss whether this feature should be added to
+Gomail or not.

+# Gomail
+[](https://travis-ci.org/go-gomail/gomail) [](http://gocover.io/gopkg.in/gomail.v2) [](https://godoc.org/gopkg.in/gomail.v2)
+
+## Introduction
+
+Gomail is a simple and efficient package to send emails. It is well tested and
+documented.
+
+Gomail can only send emails using an SMTP server. But the API is flexible and it
+is easy to implement other methods for sending emails using a local Postfix, an
+API, etc.
+
+It is versioned using [gopkg.in](https://gopkg.in) so I promise
+there will never be backward incompatible changes within each version.
+
+It requires Go 1.2 or newer. With Go 1.5, no external dependencies are used.
+
+
+## Features
+
+Gomail supports:
+- Attachments
+- Embedded images
+- HTML and text templates
+- Automatic encoding of special characters
+- SSL and TLS
+- Sending multiple emails with the same SMTP connection
+
+
+## Documentation
+
+https://godoc.org/gopkg.in/gomail.v2
+
+
+## Download
+
+ go get gopkg.in/gomail.v2
+
+
+## Examples
+
+See the [examples in the documentation](https://godoc.org/gopkg.in/gomail.v2#example-package).
+
+
+## FAQ
+
+### x509: certificate signed by unknown authority
+
+If you get this error it means the certificate used by the SMTP server is not
+considered valid by the client running Gomail. As a quick workaround you can
+bypass the verification of the server's certificate chain and host name by using
+`SetTLSConfig`:
+
+ package main
+
+ import (
+ "crypto/tls"
+
+ "gopkg.in/gomail.v2"
+ )
+
+ func main() {
+ d := gomail.NewDialer("smtp.example.com", 587, "user", "123456")
+ d.TLSConfig = &tls.Config{InsecureSkipVerify: true}
+
+ // Send emails using d.
+ }
+
+Note, however, that this is insecure and should not be used in production.

+# quotedprintable
+
+## Introduction
+
+Package quotedprintable implements quoted-printable and message header encoding
+as specified by RFC 2045 and RFC 2047.
+
+It is a copy of the Go 1.5 package `mime/quotedprintable`. It also includes
+the new functions of package `mime` concerning RFC 2047.
+
+This code has minor changes with the standard library code in order to work
+with Go 1.0 and newer.
