1.3.0.rc1 (08/03/13)

• add activerecord gem as a dependency of the main AR-JDBC gem
• override to_sql due AR 4.0 - we want to consume the passed binds array
• [sqlite3] introduce Version constant (returned from sqlite_version)
• execute expects skip_logging param on AR <= 3.0 (+ does not accept binds)
• we shall not do any to_sql in any of the exec_xxx methods
• [postgres] array column defaults more reliable (ported from Rails)
• [mssql] review MSSQL date-time handling - no need for that customized quoting
• [mssql] MSSQL - rake db:migrate:reset can drop database
• [oracle] handle null strings (e.g. returned on XML columns) instead of NPE
• [oracle] get rid of oracle's execute_id_insert not sure how it ever worked
• [oracle] sequence quoting + insert refactoring + support for RETURNING
  revisit insert / insert_sql / exec_insert to work for all ARs we support
• [db2] refactor DB2's last_insert_id using IDENTITY_VAL_LOCAL()
• [db2] DB2 supports standalone VALUES statements (just like Derby does)
• [derby] last_insert_id for Derby using IDENTITY_VAL_LOCAL()
• [derby] only hookup SQL checks on #execute when no #exec_query etc. available
• [sqlite] query-ing last_insert_id after each INSERT seems redundant
• [sqlite] a saner way of getting last_insert_row_id() via the JDBC API
• better last_inserted_id unwrapping on the base (jdbc) adapter level
• [postgres] support exec_insert with PS + make sure RETURNING works
• (thread_safe based) quoted column/table name cache implementation
  currently used with PostgreSQL, Oracle and MS-SQL adapter (#432)
• [mssql] prevent special column corruption of ORDER BY (#431)
• [db2] fix error with timezone + use default date and time parsing
• [db2] fix error on named index removing
• [postgres] fix array values escaping: backslashes should be escaped too
• [postgres] fix add_column / change_column with arrays
• [mssql] support for running with official MSSQL driver adapter: sqlserver
• [mssql] visitor update (based on built-in) to better resolve ORDER BY
• [mssql] handle SELECT DISTINCT correctly with LIMIT (#154)
• add_limit_offset! / add_lock! only to be available before AREL (2.3)
• remove Arel::SqlCompiler extensions - was only available with AR 3.0.0 pre
• refactored AREL support - esp. visitor resolution - simpler & more reliable
• [postgres] handle DISTINCT correctly with backwards-compat (#418)
• [firebird] full featured support - first class firebird_connection method
• [jdbc-] jdbc-firebird - packaged JayBird JDBC driver (gem) for FireBird 2.2.3
• [postgres] fix array quoting
• implemented support for returning Ruby Date/Time objects from JDBC
  allows such Ruby objects to be returned in custom SELECTs as well (#349)
• introduce a (better) update_lob_value as a write_large_object replacement
• beyond second precision with timestamp values for adapters that support 'em
• rename MissingFunctionalityHelper -> TableCopier
• finishing prepared statement support for all (Java API now stable), handles
  exec_query, exec_update, exec_delete and exec_insert
• use init connection to check if connection_alive_sql needed (old driver)
• JDBC API based savepoint support (that should work for all adapters)
• remove connection.config= and make sure it does not change config
• avoid executing mysql/sqlite3 JDBC type resolving code (for some speed up)
• simplify native_database_types - now on adapter + overriden avoids jdbc
• [mysql] support canceling a timer for wrapped (JNDI) connections as well
• [mysql] refactor cancel timer (field access) to work correctly (#413)
• Java API: introduce newConnection + refactor @connection_factory to Java
• [postgres] missing point casting code + string to bit casts (#60)
• [derby] tables should only return those from current schema
• [derby] set current schema thus identifiers get resolved (closes #408)
• [derby] no connection_alive_sql needed since Derby 10.8
• [postgres] make sure uuid is correctly used/resolved as PK (AR 4.0)
• [postgres] match pk_and_sequence_for with AR 4.0
