- Plugins API. - Feature CORE-2700 - UDR (User Defined Routines) Engine - C++ API supporting functions, triggers and stored procedures. - Feature CORE-2470 - Support for alternate format of strings literals. - Feature CORE-2310 - DDL triggers. - Feature CORE-2312 - PSQL Packages. - Feature CORE-1209 - CONTINUE statement. - Feature CORE-1180 - DDL syntax to change (not) nullable state of columns. - Feature CORE-2090 - Support OVER () clause with current aggregate functions. - Fixed CORE-2699 - Common table expression context could be used with parameters. - Introduce ODS 12.0. - Work in progress in type-safe parser. - Refactor some DDL commands (procedures and triggers) from DYN to DdlNodes. - Refactor virtual tables to use a class hierarchy instead of namespaces. This is basic thing, not based on the changes done in Vulcan. Window functions is based on this work. - Refactor COMMENT ON and DROP FUNCTION from DYN to DdlNodes. COMMENT ON do not use GDML anymore, it uses DSQL with PreparedStatement class. - Refactor EXECUTE BLOCK to StmtNodes. - Refactor the IUDF to SysFunctions. That eliminates RDB$GET_CONTEXT and RDB$SET_CONTEXT from RDB$FUNCTIONS.
