 ## Version 3.0beta2 (TBD)
 
 ### Changes
+
 * The parser used to always return NSMutableStrings, but may now return NSString instead, for strings with no escapes in them. This change speeded up the parser by about 30% on samsoffes' benchmark.
+* Recent refactoring to clean up the code had negative impact on the performance in samsoffes' comparative benchmark. Most of this was reclaimed, but we are still a bit slower than beta1 in his test. Particularly for writing. (We are, however, not slowest.)
 
 ### Enhancements
+
 * [Issue 40][#40]: Remove unnecessary script phase build
 * [Issue 55][#55]: SBJsonStreamWriter stringCache is now using NSCache instead of NSMutableDictionary. This firstly means it is now thread-safe, and secondly that it will free up memory automatically if the OS requests it.
