+Version 2.13.4 (26-Oct-2011)
+Bug Fixes
+=========
+1. The -sorted option (chromsweep) in intersectBed now obeys -s and -S.  I had neglected to implement that. Thanks to Paul Ryvkin for pointing this out.
+2. The -split option was mistakenly splitting of D CIGAR ops.
+3. The Makefile was not including zlib properly for newer versions of GCC. Thanks to Istvan Albert for pointing this out and providing the solution.
+
+Improvements
+============
+1. Thanks to Jacob Biesinger for a new option (-D) in closestBed that will report _signed_ distances.  Moreover, the new option allows fine control over whether the distances are reported based on the reference genome or based on the strand of the A or B feature. Many thanks to Jacob.
+2. Thanks to some nice analysis from Paul Ryvkin, I realized that the -sorted option was using way too much memory in certain cases where there is a chromosome change in a sorted BED file.  This has been corrected.
