Revision history for Perl extension Data::BitStream.
0.08    16 Aug 2014
        - Updates to documentation.
        - Goldbach encoding almost 2x faster (sped up pair search).
0.07    1 Jan 2013
        - Change from Mouse to Moo.  Mouse has great performance, but the Perl
          community is moving toward Moo/Moose and away from Any:Moose and
          Mouse.  In most cases Moo will be similar performance assuming the
          Class::XSAccessor module is installed.
        - Remove some Unicode characters that snuck into references.
        - Much faster primes for big Goldbach codes.  DBXS is still ~30x
          faster overall, but almost all of that is the pair search.
        - Add BER and Varint codes.
0.06   28 May 2012
        - Make all tests numbered.
        - Documentation additions (Pod Coverage testing).
        - get_arice / put_arice modify the k parameter, just like XS code.
        - Update Additive / Goldbach to reflect DBXS and MPFS changes.
0.05   17 May 2012
        - Make a couple 64-bit tests work properly with the 'xs' module on
          LLP64 systems.
        - Add put_raw, from_raw uses it.
        - String has custom to_raw and put_raw.
        - Inline C for decorrelator / predictor in image compression example.
        - Better behavior when doing bad reads.
        - Unify a lot of error strings.
        - Add generalized Fibonacci coding (order 2-16).
        - Add additive and Goldbach G1/G2 codes from Fenwick's 2002 IEEE paper.
        - Add comma codes (including ternary comma codes e.g. Fenwick 1996).
        - Add block-based taboo codes (Pigeon 2001).
0.04    9 Nov 2011
        - Fix late regression in one of the tests, unpack "W" -> "C".
        - Minor test and documentation changes.
        - Make most error strings consistent.
0.03   Mon Nov  7 06:00:00 2011
        - More work on unit tests.
        - Add BLVec class to use XS.  Inefficient but it works (and even with
          the silly setpos/setlen after every call, it's much faster than PP).
        - Don't use Vec and BitVec implementations unless specifically asked.
        - Lossless image codec example.
        - Simple file support (read / write).
        - Text methods (code_get, code_put, add_code)
        - Performance.
        - Clarify POD compression example slightly.
        - More tests on 32-bit and big-endian machines.
0.02  Fri Sep 30 08:16:13 2011
        - Create dist with tool instead of by hand.  Uses version number.
        - WordVec was setting the Vec variables.
0.01  Mon Sep 26 10:12:53 2011
        - original version; created by h2xs 1.23 with options
                -XAn Data::BitStream
        - 24 Sep 2011, add Boldi-Vigna Zeta, Levenstein Codes, and Baer codes
        - 19 Sep 2011, make Golomb take a sub, better default impls
        - 14 Sep 2011, add skip(), optimizations
        - 13 Sep 2011, more tests, harden the reader/writer distinction
        - 12 Sep 2011, add Delta and Omega
        - 11 Sep 2011, add ExpGolomb, and fix readahead
        - 9 Sep 2011, split into Base/impls/codes, first unit tests,
                add Fibonacci, Golomb, and Rice encoding.
        - 8 Sep 2011, Vec and BitVec code, with Gamma and GG3
        - 24 Aug 2011, first Perl version, Unary
