9 revision 1.80 2014-10-05
10 ----------------------------
11 - Fix erroneous behavior of is_literal_value($) wrt { -ident => ... }
12 - Explicitly croak on top-level special ops (they didn't work anyway)
14 revision 1.79 2014-09-25
15 ----------------------------

28 - Improve signatures/documentation of is_same_sql_bind / eq_sql_bind

40 be raised for a while before properly fixing this, to avoid quiet
41 but subtle changes to query results in production

43 operators (likely to be removed before 2.0)
45 - Warn when using an inequality operator with a multi-value array to

47 this behavior due to backwards comp concerns)

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