Fix

Fix decoding error for embedded entry-hyperlinks

5.4.0

Merge pull request #322 from contentful/feature/sync-limit

Add setting optional sync "limit" parameter

5.3.1

• Speed up link resolving

5.3.0

• Each call to handleJSON creates a local JSONDecoderinstance which uses its own LinkResolver instance. This change fixes issues causing race conditions during decoding response.
• Improved the fetch* methods so the private/internal methods do not call public methods which caused issues when trying to debug and trace the calls. The public fetch* methods are defined in the Client+Fetch.swift
• The public fetch* methods do not change the state of the Client anymore.
• Updated documentation for the fetch* calls.

5.2.0

Breaking change:

• Enforced class requirement on the EntryDecodable. Types conforming to the protocol must be declared as classes due to async mutations in the constructor.

5.1.3

Remove Field warning

5.1.2

• Properly parse nil value on decoded JSON data
• Bump JSON from 2.2.0 to 2.3.1

5.1.1

Fix:

• Send only SyncSpace parameters when accessing the next page of data to be synced

5.1.0

• Switched to using Swift.ResultType (Breaking Change)
• Updated Venmo/DVR
• Fixed race condition issues with link resolutions
• Updated QueryTests to work with new Contentful response
• Exposed a method that allows filtering content by link reference's id
• Updated docs
