Feature: Excel compatibility option added for writing CSV files
...
While Excel 2010 can read CSV files with a simple UTF-8 BOM, Excel2007 and earlier require UTF-16LE encoded tab-separated files.
The new setExcelCompatibility(TRUE) option for the CSV Writer will generate files with this formatting for easy import into Excel2007 and below.

Added a cacheMethodIsAvailable() method to all cell cache classes, making it easier to identify if all the necessary classes/functions are available for each caching option.
...
Renamed the factory getCacheStorageMethods() method to getAllCacheStorageMethods(), returning all cache options in the library.
Wrote a new factory getCacheStorageMethods() method to return an array of those cache methods that are available with the current build of PHP (extensions tested, etc).
Refactored factory initialize() method to use the cacheMethodIsAvailable(), so factoring the logic for testing methods out of the factory.
