1 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
2 *** INCOMPATIBLE CHANGES:
3 * SQLT no longer supports setting separate conflicting values for the now
4 deprecated 'quote_table_names' and 'quote_field_names'. Instead their values
5 are proxied to the new 'quote_identifiers'. If 'quote_identifiers' is
6 supplied, the legacy settings are ignored (with a warning). If nothing is
7 specified the default is TRUE as before. If only one is specified - default
8 to its value for everything, and if both are specified with a conflicting
9 value an exception is thrown.
10 * Partial quoting support has been added in SQLite. It is currently disabled by
11 default, you need to request is explicitly with quote_identifiers => 1. In a
12 future version of SQL::Translator *THIS DEFAULT BEHAVIOR WILL CHANGE*.
13 If you do NOT WANT quoting, set quote_identifiers to a false value to
14 protect yourself from changes in a future release.
