16 ----------------------------
17 - Fix erroneous behavior of is_literal_value($) wrt { -ident => ... }

20 revision 1.79 2014-09-25
21 ----------------------------

29 revision 1.78 2014-05-28

34 - Improve signatures/documentation of is_same_sql_bind / eq_sql_bind

48 - Deprecate and warn when supplying an empty arrayref to like/not_like
49 operators (likely to be removed before 2.0)
51 - Warn when using an inequality operator with a multi-value array to
52 arrive at what amounts to a 1=1 condition (no pre-2.0 plans to fix
53 this behavior due to backwards comp concerns)
54 - Fix false negative comparison of ORDER BY <function> ASC

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