This is mostly information aggregator type blog but I wanted to let the SP 2013 search community know of the Office / SharePoint 2013 SP1 details. Mostly bug fixes, a good fix for FQL/KQL highlighting and one interesting bit "Search schema compression is now enabled by default to allow larger search schemas".
A detailed list of SP1 fixes is available for download.
SP1 includes all the Public Updates (PU) and Cumulative Updates (CU) that have been released since the 2013 family of products first became available, up to the December 2013 CU and January 2014 PU.
