280 Version 1.50 was a major internal refactoring of SQL::Abstract.
281 Great care has been taken to preserve the published behavior
282 documented in previous versions in the 1.* family; however,
283 some features that were previously undocumented, or behaved.
284 differently from the documentation, had to be changed in order
285 to clarify the semantics. Hence, client code that was relying
286 on some dark areas of SQL::Abstract v1.* might behave differently
