155 * Add missing quote function to SQLServer producer
156 * Fix incorrect Parser::DBI documentation (RT#60878)
160 [ INCOMPATIBLE CHANGES ]
162 * SQLT no longer supports setting separate conflicting values for the now
163 deprecated 'quote_table_names' and 'quote_field_names'. Instead their values
164 are proxied to the new 'quote_identifiers'. If 'quote_identifiers' is
165 supplied, the legacy settings are ignored (with a warning). If nothing is
166 specified the default is TRUE as before. If only one is specified - default
167 to its value for everything, and if both are specified with a conflicting
168 value an exception is thrown.
170 * Partial quoting support has been added in SQLite. It is currently disabled by
171 default, you need to request is explicitly with quote_identifiers => 1. In a
172 future version of SQL::Translator *THIS DEFAULT BEHAVIOR WILL CHANGE*.
173 If you do NOT WANT quoting, set quote_identifiers to a false value to
174 protect yourself from changes in a future release.
