Fixed a bug that caused the internal element positions cache to not update when a subdocument is changed.

3.7.0

Swift GM

3.6.1

Output no unneeded whitespace in JSON

3.6.0

• Use Swift snapshot 08-18
• Added Document.append(contentsOf: )
• Better implementation of the == operator for Documents
• Added Document.type(of: ) to check the type of a BSON element. This is faster than instantiating all the element data.

3.5.6

• More Document performance improvement
• More ObjectId instantiation performance
• HexString performance

3.5.5

• Added makeDocument() to a sequence of Documents, like [Document], to convert it to a single array document
• Improved the JSON date parser (ISO8601)
• Added additional subscripts for Document so you can let val = doc["key", "subKey", "subKeyKey"]
• Meow, so you can now let meow = Meow() 😼
• Added Document.flatten() and Document.flattened()
• Fixed a bug that would crash BSON after generating 32767 ObjectId's

3.5.4

• Improved performance of document.count
• Added + and += operators to combine documents. Ha, that's something even Dictionary doesn't have.

3.5.3

HUGE performance increase for large documents

ISO8601 fix

• Cross-platform ISO8601 parsing
