23 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
24 *** INCOMPATIBLE CHANGES:
25 * SQLT no longer supports setting separate conflicting values for the now
26 deprecated 'quote_table_names' and 'quote_field_names'. Instead their values
27 are proxied to the new 'quote_identifiers'. If 'quote_identifiers' is
28 supplied, the legacy settings are ignored (with a warning). If nothing is
29 specified the default is TRUE as before. If only one is specified - default
30 to its value for everything, and if both are specified with a conflicting
31 value an exception is thrown.
32 * Partial quoting support has been added in SQLite. It is currently disabled by
33 default, you need to request is explicitly with quote_identifiers => 1. In a
34 future version of SQL::Translator *THIS DEFAULT BEHAVIOR WILL CHANGE*.
35 If you do NOT WANT quoting, set quote_identifiers to a false value to
36 protect yourself from changes in a future release.
37 * Bump the default MySQL parser version to MySQL 4.0
