260 Version 1.50 was a major internal refactoring of SQL::Abstract.
261 Great care has been taken to preserve the published behavior
262 documented in previous versions in the 1.* family; however,
263 some features that were previously undocumented, or behaved.
264 differently from the documentation, had to be changed in order
265 to clarify the semantics. Hence, client code that was relying
266 on some dark areas of SQL::Abstract v1.* might behave differently
269 ----------------------------
