Notable changes between the WIP draft and the v1 specification are: - Specify error types - Clarify return values of expressions that encounter errors - Clarify that missing attributes result in an error and the expression returning it's default value - Add support for boolean to integer and integer to boolean type casting - Clarify the order of operations - Clarify how user defined functions work - Define the default "zero" values for the built in types - Clarify that string comparisons are case sensitive - Specify which characters are treated as whitespace for the TRIM function - Specify that functions must still return values along with errors, as well as the behaviour when user defined function do not do this correctly - For the fail fast error handling mode, expressions now return the zero value for their return type when they encounter an error, rather than undefined
