13 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
14 *** INCOMPATIBLE CHANGES:
15 * SQLT no longer supports setting separate conflicting values for the now
16 deprecated 'quote_table_names' and 'quote_field_names'. Instead their values
17 are proxied to the new 'quote_identifiers'. If 'quote_identifiers' is
18 supplied, the legacy settings are ignored (with a warning). If nothing is
19 specified the default is TRUE as before. If only one is specified - default
20 to its value for everything, and if both are specified with a conflicting
21 value an exception is thrown.
22 * Partial quoting support has been added in SQLite. It is currently disabled by
23 default, you need to request is explicitly with quote_identifiers => 1. In a
24 future version of SQL::Translator *THIS DEFAULT BEHAVIOR WILL CHANGE*.
25 If you do NOT WANT quoting, set quote_identifiers to a false value to
26 protect yourself from changes in a future release.
27 * Bump the default MySQL parser version to MySQL 4.0
