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