CHANGES & IMPROVEMENTS:

- generation of unique password lists (i.e., lists where each entry must occur
  only once; activated by the option "Exclude duplicate entries" in the
  "Advanced Password Options") has been optimized for speed (at the expense
  of a roughly doubled memory requirement) and is much faster now even for very
  large password lists (>1 million entries)
- when generating password lists to files with the "Exclude duplicates" option
  activated, checking for duplicates is performed in-memory now instead of
  searching the entire file contents; as a consequence, the amount of passwords
  that can be generated in this case is limited by the memory available to a
  32-bit application like PWGen (... but it's also much faster now)
  (thanks to Hussein for reporting & valuable suggestions!); note that when the
  list is appended to an existing file, the file contents will NOT be searched
  anymore for already existing password entries, i.e., a new unique password
  list will be appended to the file

FIXES:

- generation of unique password lists didn't work properly for passphrases
  (composed of words from a word list)
- fixed a bug in the internal word list ("diceware8k" module), which reduced its
  effective size to 8191 instead of 8192 words (list contained an empty string
  due to the faulty encoding of a string in the C source code file); apart from
  (slightly!) reducing the entropy (12.9998 vs. 13), this empty word reduced the
  number of words in passphrases when randomly chosen and sometimes caused
  errors when converting passwords to UTF-8 Unicode encoding
- "out of memory" errors were not displayed correctly, a cryptic message was
  shown without the actual information
