-Added __str__() and __repr__() methods to pefile's structures. Now it's possible to navigate through the contents much more comfortably from an interactive Python command line. Just typing the name of a structure or doing a print on it will return all the fields and their contents.
-Bugs fixed when parsing the resource information
-Improved parsing of imported symbols. Import by ordinal and name is much more clear now. The ImportData instances have a new attribute, 'import_by_ordinal', indicating whether a symbol is imported by name, in that case the 'ordinal' attributes will contain the ordinal. Otherwise the attribute 'name' will contain the name of the imported symbol.
-Added CheckSum verification and generation methods. verify_checksum() will return True/False indicating whether the value in the file's OptionalHeader CheckSum field contains the real CheckSum of the file. generate_checksum() will calculate the checksum over the file's data. If one modifies fields and writes the changes to disk it's possible to update the checksum by reloading the modified field and setting the CheckSum field to generate_checksum()'s result.
-Other minor fixes

-Bumped version to 1.2.9a

Added computation of MD5, SHA-1, SHA-256 and SHA-512 on a per-section basis. The results are always reported when invoking the dump_info() method in the PE instance.
SHA-256 and SHA-512 are calculated only in Python 2.5 onwards which includes them in the hashlib module.
The SectionStructure instances now sport the following methods: get_hash_sha1(), get_hash_sha256(), get_hash_sha512(), get_hash_md5()

-Bumped version number to 1.2.8
-Faster entropy calculation by Gergely Erdelyi
-Added some intelligence handling unicode strings in the resources information. Strings in the resources seem to always be Pascal style, added support for those
-Changed some loops iterating using range() to use xrange() instead. It will make the code more robust/faster whenever invalid large numbers of elements are specified in different arrays
-As per c1de0x suggestion, added set_data() method to SectionStructure
-Added get_entropy() method to SectionStructure. Now it's only calculated on demand or when doing a dump_info()
-c1de0x pointed out a redundant length check in __unpack_data__ and __unpack__. Now the exception raised by the latter is caught by the former and a warning added if a structure can't be parsed because of missing data
-Fixed bug parsing export directory. Warning messages are added if it's found to be invalid
-Fixed bug parsing the IAT. Some broken samples could crash pefile. The invalid IAT is now reported in the warnings
-New method: relocate_image(new_ImageBase) will apply the relocation information, if any, to the image
-get_memory_mapped_image() now supports and additional keyword argument, "ImageBase". By specifying an address it will return a data relocated (if the PE contains relocation information) as if it had been relocated to the new ImageBase
-Added full family of bytes/word/dword/qword manipulation methods (used by the relocation functionality):
-get_data_from_dword(dword), get_dword_from_data(data, offset), get_dword_at_rva(rva), get_dword_from_offset(offset), set_dword_at_rva(rva, dword), set_dword_at_offset(offset, dword)
