Updated release history to reflect 2.10.0

RELEASE_HISTORY

-Version 2.9.1 (August-16-2010)
+Version 2.10.0 (September-21-2010)
+==New tools==
+1. annotateBed. Annotates one BED/VCF/GFF file with the coverage and number of overlaps observed
+from multiple other BED/VCF/GFF files. In this way, it allows one to ask to what degree one feature coincides with multiple other feature types with a single command. For example, the following will annotate the fraction of the variants in variants.bed that are covered by genes, conservaed regions and know variation, respectively.
+$ annotateBed -i variants.bed -files genes.bed conserv.bed known_var.bed
+
+This tool was suggested by Can Alkan and was motivated by the example source code that he kindly provided.
+
+==New features==
+1. New frequency operations (freqasc and freqdesc) added to groupBy.  These operations report a histogram of the frequency that each value is observed in a given column.
+2. Support for writing uncompressed bam with the -ubam option.
+3. Shorthand arguments for groupBy (-g eq. -grp, -c eq. -opCols, -o eq. -opCols).
+4. In addition, all BEDTools that require only one main input file (the -i file) will assume that input is
+coming from standard input if the -i parameter is ignored. For example, the following are equivalent:
+$ cat snps.bed | sortBed –i stdin
+$ cat snps.bed | sortBed
+
+As are these:
+$ cat data.txt | groupBy -i stdin -g 1,2,3 -c 5 -o mean
+$ cat data.txt | groupBy -g 1,2,3 -c 5 -o mean
+
+==Bug fixes==
+1. Increased the precision of the output from groupBy.

 ==New tools==
 1. unionBedGraphs.  This is a very powerful new tool contributed by Assaf Gordon from  CSHL.  It will combine/merge multiple BEDGRAPH files into a single file, thus allowing comparisons of coverage (or any text-value) across multiple samples.

 Version 2.8.3 (July-25-2010)
 1. Fixed bug that caused some GFF files to be misinterpreted as VCF.  This prevented the detection of overlaps.
 2. Added a new "-tag" option in bamToBed that allows one to choose the _numeric_ tag that will be used to populate the score field.  For example, one could populate the score field with the alignment score with "-tag AS".
