5 revision 1.80 2014-10-05
6 ----------------------------
7 - Fix erroneous behavior of is_literal_value($) wrt { -ident => ... }
8 - Explicitly croak on top-level special ops (they didn't work anyway)
10 revision 1.79 2014-09-25
11 ----------------------------
12 - New exportable functions: is_literal_value($) and is_plain_value($)
13 - New attribute 'escape_char' allowing for proper escape of quote_chars
14 present in an identifier

19 revision 1.78 2014-05-28
20 ----------------------------
21 - Fix parsing of binary ops to correctly take up only a single LHS
22 element, instead of gobbling up the entire parse-to-date
23 - Explicitly handle ROW_NUMBER() OVER as the snowflake-operator it is
24 - Improve signatures/documentation of is_same_sql_bind / eq_sql_bind

33 ----------------------------
34 - *UPCOMING INCOMPATIBLE BUGFIX*: SQLA used to generate incorrect SQL
35 on undef-containing lists fed to -in and -not_in. An exception will
36 be raised for a while before properly fixing this, to avoid quiet
37 but subtle changes to query results in production
38 - Deprecate and warn when supplying an empty arrayref to like/not_like
39 operators (likely to be removed before 2.0)
41 - Warn when using an inequality operator with a multi-value array to
42 arrive at what amounts to a 1=1 condition (no pre-2.0 plans to fix
43 this behavior due to backwards comp concerns)
44 - Fix false negative comparison of ORDER BY <function> ASC
45 - More improvements of incorrect parsing (placeholder at end of list
47 - Fix typos in POD and comments (RT#87776)
48 - Augment -not_bool example with nesting (RT#89601)

57 revision 1.73 2012-07-10

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