207
208* New Features
209

213      both easier and faster. Removes the need for two command lines and
214      many extraneous lines of output.

216    and omits self matches.

233
234* Bug Fixes
235
236 - Fixed failure to close files after reading in engine.c
237 - Fixed routine to read headers of matching hashes on Windows.
238 - Fixed handling of symbolic links
239 - Fixed cosmetic bug to display error messages if file open fails
240     (e.g. Permission denied, etc)
241 - Removed quotation marks from the signatures but not the file names.
242     Filenames may contain spaces, but signatures may not. Two bytes
243     per line adds up when we starting compiling large hash sets.
244 - Redirected all error messages to stderr instead of stdout
245 - Removed duplicate defines at the start of engine.c
246 - Replaced all references to u32 with C99 standard uint32_t
247 - Added error checking for memory allocation in main.c:main() and
248     engine.c:hash_file()
249 - Removed useless logical AND of 0xFFFFFFFF from rolling hash update
