1.3.0.beta1 (04/11/13)

• [db2] map datetime / timestamp / time types + correct time handling on AS400
• AREL values passed to #to_sql not handled correctly on AR-3.0 (#365)
• (Ruby) API cleanup - removed ArJdbc::Jdbc::Mutex and CompatibilityMethods
• new base implementations for all exec_xxx methods (introduced in AR 3.1)
• returning AR::Result from #exec_query + #exec_query_raw for old behavior
• [mssql] #table_exists? does not filter views (only #tables does)
• [postgres] introduced new types on AR 4.0 - same ones native adapter supports
  (uuid values, arrays, json, hstore, ltree, PG ranges, interval, cidr etc.)
• Java API - now compiled with Java 1.6 since we're using JDBC 4 API anyways
• generic #exec_query returning AR::Result + #exec_raw_query for compatibility
• [postgres] improve #insert_sql (uses primary_key, supports all AR versions)
• [postgres] support config[:insert_returning]
• [postgres] always return correct primary key (failing if no sequence)
• Java API - xxxToRuby refactorings - to allow for more flexible overrides
• [postgres] support BIT(n) type where n > 1 as "bit strings"
• [postgres] #disable_referential_integrity on USER level (AR 4.0 compatible)
• Java API - allow objectToRuby and arrayToRuby overrides
• allow more-intuitive initialize arguments when sub-classing JdbcColumn
• do not translate native (Java) exceptions into StatementInvalid (from #log)
• Java API - replaced #tableLookupBlock with (a new) #matchTables
• [mssql] better message for jTDS driver bug (support disabling explain)
• Java API:- accept (and use) catalog as arg[1] in #columns which does leads to
  a refactoring of #extractTableName to accept a catalog name
• [mssql] current_user and (change-able) default_schema support (#311)
• [sqlite3] correct empty insert statement value (on AR-4.0)
• Java API - do not wrap runtime exceptions when handling throwables
• [mysql] correct empty insert statement value (was not working on 4.0)
• Java API - handle :xml and :array AR column type to JDBC type conversion
• Java API - SQL Array and Object JDBC type (to Ruby) mappings
• Java API - reviewed (and updated) JDBC type handling for adapters :
  • FLOAT/DOUBLE types should be handled (just like REAL) as Double-s
  • NUMERIC/DECIMAL values should be handled as BigDecimal-s
  • BIT/BOOLEAN should be converted to (Ruby) true/false by default
  • NULL should always be returned as nil
  • close binary/character stream & free SQLXML once converted
  • JDBC 4.0 N(CHAR) types should be handled
• JdbcConnectionFactory.newConnection now throws SQLException - this is backwards
  incompatible but most extension do not need to deal with this interface (#347)
• (AR 4.0 compatible) transaction isolation support
• Java API - deprecate SQLBlock class in favor of a parameterized Callable iface
• Java API - #retry makes no sense during #rollback (should use the same connection)
• [postgres] session variables support (from configuration)
• [mysql] session variables support (from configuration)
• [mysql] :strict config option, for STRICT_ALL_TABLES on AR-4.0
• AR 4.0 (master) compatible #rename_table_indexes and #renamed_column_indexes
• [postgres] no need to clear_query_cache after insert on AR-2.3's #insert_sql
• Java API - connection #execute_delete "alias" for #execute_update
• [derby] XMLPARSE when inserting into an XML column type ...
  but still can not retrieve XML values using SELECT * FROM
• [sqlite3] IndexDefinition#unique should be a true/false
• [mssql] execute_procedure support, AR-SQLServer style (#266)
• [mssql] #charset, #current_database
• [mssql] config[:database] support + switching using #use_database (#311)
• [mssql] explain support
• [mssql] better query type detection - make sure WITHs work as SELECts
• [mssql] make sure there's a column class (#269) + better special column magic
• [mssql] better - working date/time quoting (with some ms precision support)
• Java API - re-arrange JDBC (to-ruby) type conversion methods
• [mssql] fix Model.first on SQL Server 2000 when called with only order
• [oracle] XMLTYPE column support - can't test due bug in driver
• [db2] working XML column type support
• [oracle] MATRIALIZED VIEWS/SYNONYMS should be usable on table_exists?
• a better (default) table_exists? (aligned with columns_internal) for all
• Java API - add #mapTables for OOP-ish mapping of results from #getTables
• [db2] [derby] some (working) connection alive sql (db gurus should help)
• [oracle] a working connection alive sql
• [db2] seems like DB2 on ZOS used a non-existing get_primary_key method
• do not call_discovered_column_callbacks for extending column impls
• [hsqldb] a 'valid' connection alive SQL for HSQLDB
• ActiveRecord::AbstractAdapter#exec_insert has 5 args in AR 4.0 (master)
• no need for a ArJdbc::Version module simply use ArJdbc::VERSION
• support auto-loading of adapter gems e.g. when specified in a Gemfile
• load out raltie from arjdbc instead of activerecord-jdbc-adapter thus it will
  work consistently even if only a specific adapter gem is specified in Gemfile
• make sure we require arjdbc instead of just arjdbc/jdbc from adapters
