Use LoggerAPI debug logging instead of print in DataSender (#140)

This gives users of Swift-SMTP more control over stdout output.

 ## Swift Version
 
-macOS & Linux: `Swift 3.1.1`
+macOS & Linux: `Swift 5.2` or above.
+
+## Installation
+
+You can add `SwiftSMTP` to your project using [Swift Package Manager](https://swift.org/package-manager/). If your project does not have a `Package.swift` file, create one by running `swift package init` in the root directory of your project. Then open `Package.swift` and add `SwiftSMTP` as a dependency. Be sure to add it to your desired targets as well:
+
+```swift
+// swift-tools-version:4.0
+
+import PackageDescription
+
+let package = Package(
+    name: "MyProject",
+    products: [
+        .library(
+            name: "MyProject",
+            targets: ["MyProject"]),
+    ],
+    dependencies: [
+        .package(url: "https://github.com/Kitura/Swift-SMTP", .upToNextMinor(from: "5.1.0")),    // add the dependency
+    ],
+    targets: [
+        .target(
+            name: "MyProject",
+            dependencies: ["SwiftSMTP"]),                                                           // add targets
+        .testTarget(                                                                                // note "SwiftSMTP" (NO HYPHEN)
+            name: "MyProjectTests",
+            dependencies: ["MyProject"]),
+    ]
+)
+```
+
+After adding the dependency and saving, run `swift package generate-xcodeproj` in the root directory of your project. This will fetch dependencies and create an Xcode project which you can open and begin editing.
+
+## Migration Guide
+
+Version `5.0.0` brings breaking changes. See the quick migration guide [here](https://github.com/Kitura/Swift-SMTP/blob/master/migration-guide.md).
 
 ## Usage
 
-Use the `SMTP` struct as a handle to your SMTP server. If your server requires a SSL/TLS connection, you can specify an `SSL` config and include it in your `SMTP` handle:
+Initialize an `SMTP` instance:
 
 ```swift
 import SwiftSMTP
 
-// Create an `SSL` config
-#if os(Linux)
-    let certificateFilePath = "~/cert.pem"
-    let keyFilePath = "~/key.pem"
-    let ssl = SSL(withCACertificateDirectory: nil, usingCertificateFile: certificateFilePath, withKeyFile: keyFilePath)
-#else
-    let chainFilePath = "~/cert.pfx"
-    let certPassword = "password"
-    let ssl = SSL(withChainFilePath: chainFilePath, withPassword: certPassword)
-#endif
-/* Additional methods available to create an `SSL` config */
-
-// Create your `SMTP` handle
-let smtp = SMTP(hostname: "smtp.gmail.com",     // SMTP server address
-                user: "user@gmail.com",         // username to login 
-                password: "password",           // password to login
-                ssl: ssl)                       // if your SMTP server requires SSL/TLS
-                
-/* Additional parameters available to further customize your `SMTP` handle */
+let smtp = SMTP(
+    hostname: "smtp.gmail.com",     // SMTP server address
+    email: "user@gmail.com",        // username to login
+    password: "password"            // password to login
+)
 ```
 
+### TLS
+
+Additional parameters of `SMTP` struct:
+
+```swift
+public init(hostname: String,
+            email: String,
+            password: String,
+            port: Int32 = 587,
+            tlsMode: TLSMode = .requireSTARTTLS,
+            tlsConfiguration: TLSConfiguration? = nil,
+            authMethods: [AuthMethod] = [],
+            domainName: String = "localhost",
+            timeout: UInt = 10)
+```
+
+By default, the `SMTP` struct connects on port `587` and sends mail only if a TLS connection can be established. It also uses a `TLSConfiguration` that uses no backing certificates. View the [docs](https://kitura.github.io/Swift-SMTP/) for more configuration options.

 ### Send email
 
-Create a `Mail` object and use your `smtp` handle to send it. To set the sender and receiver of an email, use the `User` struct:

+<p>You can add <code>SwiftSMTP</code> to your project using <a href="https://swift.org/package-manager/">Swift Package Manager</a>. If your project does not have a <code>Package.swift</code> file, create one by running <code>swift package init</code> in the root directory of your project. Then open <code>Package.swift</code> and add <code>SwiftSMTP</code> as a dependency. Be sure to add it to your desired targets as well:</p>

-<p>Use the <code>SMTP</code> struct as a handle to your SMTP server. If your server requires a SSL/TLS connection, you can specify an <code>SSL</code> config and include it in your <code>SMTP</code> handle:</p>
+<p>You can add <code>SwiftSMTP</code> to your project using <a href="https://swift.org/package-manager/">Swift Package Manager</a>. If your project does not have a <code>Package.swift</code> file, create one by running <code>swift package init</code> in the root directory of your project. Then open <code>Package.swift</code> and add <code>SwiftSMTP</code> as a dependency. Be sure to add it to your desired targets as well:</p>

+# 5.0.0 Migration Guide
+
+- The default port is now `587`.
+
+- The `SMTP` struct is now initialized with a `TLSMode` enum instead of a `useTLS` Bool, allowing more configuration options:
+
+```swift
+/// TLSMode enum for what form of connection security to enforce.
+    public enum TLSMode {
+        /// Upgrades the connection to TLS if STARTLS command is received, else sends mail without security.
+        case normal
+
+        /// Send mail over plaintext and ignore STARTTLS commands and TLS options. Could throw an error if server requires TLS.
+        case ignoreTLS
+
+        /// Only send mail after an initial successful TLS connection. Connection will fail if a TLS connection cannot be established. The default port, 587, will likely need to be adjusted depending on your server.
+        case requireTLS
+
+        /// Expect a STARTTLS command from the server and require the connection is upgraded to TLS. Will throw if the server does not issue a STARTTLS command.
+        case requireSTARTTLS
+    }
+```
+
+# 4.0.0 Migration Guide
+
+- `User` struct now nested in `Mail` struct to avoid namespace issues [(69)](https://github.com/Kitura/Swift-SMTP/pull/69). Create a user like so:
+
+```swift
+let sender = Mail.User(name: "Sloth", email: "sloth@gmail.com")
+```
+
+- `User` properties are now public
+
+- The optional `accessToken` parameter of the `SMTP` struct has been removed. If you are using the authorization method `XOAUTH2`, pass in your access token in the `password` parameter instead. For example:
+
+```swift
+let smtp = SMTP(
+    hostname: "smtp.gmail.com",
+    email: "example@gmail.com",
+    password: "accessToken",
+    authMethods: [.xoauth2]
+)
+```
+
+- Fixed a bug where the wrong `Attachment` was used an an alternative to text content when a `Mail` was initialized with multiple `Attachment`s [(67)](https://github.com/Kitura/Swift-SMTP/pull/67)
+
+# 3.0.0 Migration Guide
+
+## Initialize `SMTP`
+
+Before `3.0.0`:
+
+```swift
+public init(hostname: String,
+            email: String,
+            password: String,
+            port: Port = Ports.tls.rawValue,
+            ssl: SSL? = nil,
+            authMethods: [AuthMethod] = [],
+            domainName: String = "localhost",
+            accessToken: String? = nil,
+            timeout: UInt = 10)
+```
+
+After `3.0.0`:
+
+```swift
+public init(hostname: String,
+            email: String,
+            password: String,
+            port: Int32 = 465,
+            useTLS: Bool = true,
+            tlsConfiguration: TLSConfiguration? = nil,
+            authMethods: [AuthMethod] = [],
+            accessToken: String? = nil,
+            domainName: String = "localhost",
+            timeout: UInt = 10)
+```
+
+## Renamed
+
+- `SSL` renamed to `TLSConfiguration`
+
+## Removed
+
+- `Port` typealias
+
+## Other Changes
+
+- `Mail` properties are now public
