   * Create only one DB connection for each host, not one per host/tbl/chunk.
   * Code assumed backtick quoting, broke on SQL_MODE=ANSI (bug #1813030).
   * There were many potential bugs with database and table name quoting.
   * Child exit status errors could be masked by subsequent successes.

2007-11-12: version 1.1.18

   * DSN Parsing was broken.

2007-11-04: version 1.1.17

   * Made command-line help easier to use.
   * Removed the dependency on Term::ReadKey.
   * Replaced some code with modules that are unit-tested.

2007-10-01: version 1.1.16

   * Made mk-checksum-filter able to compare tables in different databases.

2007-09-20: version 1.1.15

   * The CHECKSUM strategy was always disabled.

2007-09-01: version 1.1.14

   * Added documentation about the storage engine for the checksum table.
   * The --replcheck option now checks the server and its slaves.

2007-08-23: version 1.1.13

   * Added --askpass option.

2007-07-26: version 1.1.12

     was removed.

2007-07-20: version 1.1.11

   * Added --replcheck option to check --replicate results on slaves.
   * Added --recursecheck option to do --replcheck recursively.

2007-07-10: version 1.1.10

   * Handle malformed values that will return undef start and end points in
     chunking.
   * Updated documentation's example query to be run on the slave.

2007-07-10: version 1.1.9

   Changes:
   * Enabled chunking on FLOAT, DOUBLE and DECIMAL columns.

   Bugs fixed:
   * mk-table-checksum crashed when EXPLAIN said an empty table had rows.
   * mk-table-checksum failed to find rows on slaves that didn't exist
     on the master.
   * Changed from BETWEEN to WHERE clauses.

   Changes:
   * Documentation.

   * Added --defaults-file option.
   * Added standard --version command-line option.

2007-06-03: version 1.1.6

   Incompatible changes:
   * The chunking functionality no longer guarantees chunks will be no larger
     than the specified size.  Use --chunksize-exact for that.  Note that the
     chunking functionality is still experimental and likely to change further.

   Changes:
   * Chunking now works with multiple-column indexes.
   * Added --quiet option, useful for cron jobs with --replicate.
   * Added --float-precision option; works around different floating-point formats.
   * Added --sleep-coef option; sleeps a multiple of the time the last checksum took.
   * Added error handling for tables that are dropped during checksumming.
   * Added documentation on the finer points of --replicate-do and --binlog-do.

   Bugs fixed:
   * There was a race condition between listing and checksumming tables.
   * Perl's auto-vivify hashes could cause all tables to be skipped after the
     first VIEW.
   * Some DBIs did not consider ? inside a comment to be a placeholder.
   * Systems that return nothing from CHECKSUM TABLE crashed mk-table-checksum.
   * --askpass did not print a newline after reading password.

   * --replicate did not always work correctly with binlog_do_db.

2007-05-16: version 1.1.5

   Incompatible changes:
   * Output includes a new CHUNK column.
   * When using --replicate, the specified table structure needs a new 'chunk' column.

   Changes:
   * Added --chunksize and --chunkcol options to checksum tables in chunks.
   * Added --sleep option to pause between checksum queries.
   * Added --emptyrepltbl option to empty --replicate table before starting work.
   * Added --defaults-file option to read a given MySQL options file.
   * Check for existence of --replicate table before starting work.
   * Updated mk-checksum-filter to handle the new CHUNK column in the output.
   * More documentation.
   * More tests in the test suite.

   Bugs fixed:
   * The output in --replicate mode had an empty string in CHECKSUM when the
     table had no rows (bad for scriptability).
   * The --optxor optimization was broken and always disabled itself.
