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