106 * Convert SQL::Translator, ::Schema and ::Schema::* to Moo

112 standard, and avoiding MySQL bugs
116 * Fix/update quoting in PostgreSQL producer
117 * Add missing quote function to SQLServer producer
118 * Fix incorrect Parser::DBI documentation (RT#60878)
122 [ INCOMPATIBLE CHANGES ]
124 * SQLT no longer supports setting separate conflicting values for the now
125 deprecated 'quote_table_names' and 'quote_field_names'. Instead their values
126 are proxied to the new 'quote_identifiers'. If 'quote_identifiers' is
127 supplied, the legacy settings are ignored (with a warning). If nothing is
128 specified the default is TRUE as before. If only one is specified - default
129 to its value for everything, and if both are specified with a conflicting
130 value an exception is thrown.
132 * Partial quoting support has been added in SQLite. It is currently disabled by
133 default, you need to request is explicitly with quote_identifiers => 1. In a
134 future version of SQL::Translator *THIS DEFAULT BEHAVIOR WILL CHANGE*.
135 If you do NOT WANT quoting, set quote_identifiers to a false value to
136 protect yourself from changes in a future release.
