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