v0.5.8

• Implemented Fasta.__len__ (#157)
• Sequence instances can now be compared against strings (#158 thanks @Maarten-vd-Sande)

v0.5.7

• Fasta instances now have dictionary methods: Fasta.keys returns sequence names, Fasta.values returns FastaRecord instances, and Fasta.items returns a tuple of (key, value) pairs. #156 (thanks @Maarten-vd-Sande)

v0.5.6

• Support for returning zero-length sequences (#155 and #93 see example below) (thanks @prihoda!)

>>> from pyfaidx import Fasta
>>> fasta = Fasta('data/genes.fasta', strict_bounds=True)
>>> len(fasta['gi|557361099|gb|KF435150.1|'][100:100] == 0
True
