[2.0][DDC-354][DDC-425] Fixed. Encapsulated SQL logging better in the DBAL. Added binding types to DBAL mapping types as well as using these binding types in the persisters. Query and NativeQuery now support PDO binding types as well as DBAL mapping types when binding parameters.

[2.0] Fixed issue with DQL that was not considering input parameter 10. Also added support to retrieve the generated AST.

[2.0] Fixed custom functions support that was failing to be processed. Also fixed syntax error of Function support.

[2.0] Code cleanups. Preparations for DDC-193. Fixed DDC-399, type configuration remains global for now but the irritating instance methods on the Configuration have been removed. Use Type::addType et al. Added TODOs for naming standards.

[2.0] Add missing Query::HINT_CUSTOM_OUTPUT_WALKER - it wasn't possible to change the output walker before without extending and overwriting one large method in Query

[2.0][DDC-92] Fixed. Patch provided by Christian Heinrich. [DDC-274] Started some method renaming. [DDC-142] Fixed (join column names and discriminator column names dont support quoting) [DDC-258] Fixed.

[2.0][DDC-265] Partial support to inheritanceType in AnnotationExporter. Still needs to add the discriminator column.

[2.0] Fix casing bug in Parser - IfFunction checks lower-case the function name, but register methods don't.

[2.0] Refactorings in DQL parser to allow more granular enhancements scheduled for later versions. Fixed issues with missing validations of invalid ResultVariable, Unknown query components and Re-declaration of query compoenents.

[2.0] More refactorings in Annotations parser and DQL parser. Now they only use constants instead of string processment

[2.0][DDC-49][DDC-50][DDC-33] Fixed DDC-49 and DDC-50. Also addressed DDC-33. Various other small changes and fixes. For problems with proxy objects please refer to the updated documentation.

[2.0] Refactored classloader architecture. Renamed ClassLoader => GlobalClassLoader. Introduced IsolatedClassLoader that is suitable for participating in autoload stacks. Added 2 example entity classes to the sandbox with 2 xml mappings and 2 yaml mappings. Simplified sandbox setup.

[2.0] Applied fixes for character casing issues. Simplified inheritance mapping and improved handling of outer joins in Class Table Inheritance.

[2.0] More preparations to fix character casing issue. Reverted and completed ConditionalPrimary parsing and added more tests for this.

[2.0] Fixed several referential integrity issues. Fixed critical issue with inserts being run twice on postgresql/oracle. Added support for additional tree walkers that modify the AST prior to SQL construction and started to play with it in a testcase.

[2.0] Some code reordering, changes. Removed classMetadata from RangeVariableDeclaration, since it is against AST concept.

[2.0] Removed AssociationMappings from ResultSetMapping  for improved caching. Fixed caching issue with reflection classes and properties. Reimplemented and leaned up broken identifier quoting. Added support for named (native) queries. Fixed small hydration memory leak.

[2.0] Some Annotations parser docblocks, optimizations, etc. Fixed wrong syntax error token report in DQL parser

[2.0] Fixed warning in semantical error reporting (strpos with length over dql length). Fixed wrong grammar rule. Fixed wrong token position on semantical error reporting. Added more semantical checks in UpdateItem
