1.47_01 2015-02-17
    *** (EXPERIMENTAL) CHANGES THAT MAY POSSIBLY BREAK YOUR OLD APPLICATIONS ***
    - Commented OPTIMIZE out of WriteMakefile (RT #94207).
      If your perl is not compiled with -O2, your DBD::SQLite may
      possibly behave differently under some circumstances.
      (This release is to find notable examples from CPAN Testers).
    - Set THREADSAFE to 0 under Cygwin to cope with an upstream
      regression since 3.8.7 (GH #7).

    - Updated to SQLite 3.8.8.2
    - Resolved #35449: Fast DBH->do (ptushnik, ISHIGAKI)
