1 Revision history for SQL::Abstract
3 - Fix erroneous behavior of is_literal_value($) wrt { -ident => ... }
4 - Explicitly croak on top-level special ops (they didn't work anyway)
6 revision 1.79 2014-09-25
7 ----------------------------
8 - New exportable functions: is_literal_value($) and is_plain_value($)
9 - New attribute 'escape_char' allowing for proper escape of quote_chars
10 present in an identifier
11 - Deprecate { "" => \... } constructs
12 - Treat { -value => undef } as plain undef in all cases
13 - Explicitly throw on { -ident => undef }
15 revision 1.78 2014-05-28
16 ----------------------------
17 - Fix parsing of binary ops to correctly take up only a single LHS
18 element, instead of gobbling up the entire parse-to-date
19 - Explicitly handle ROW_NUMBER() OVER as the snowflake-operator it is
20 - Improve signatures/documentation of is_same_sql_bind / eq_sql_bind
21 - Retire script/format-sql - the utility needs more work to be truly
24 revision 1.77 2014-01-17
25 ----------------------------
26 - Reintroduce { -not => undef } column operator (regression from 1.75)

29 ----------------------------
30 - *UPCOMING INCOMPATIBLE BUGFIX*: SQLA used to generate incorrect SQL
31 on undef-containing lists fed to -in and -not_in. An exception will
32 be raised for a while before properly fixing this, to avoid quiet
33 but subtle changes to query results in production
34 - Deprecate and warn when supplying an empty arrayref to like/not_like
35 operators (likely to be removed before 2.0)
37 - Warn when using an inequality operator with a multi-value array to
38 arrive at what amounts to a 1=1 condition (no pre-2.0 plans to fix
39 this behavior due to backwards comp concerns)
40 - Fix false negative comparison of ORDER BY <function> ASC
41 - More improvements of incorrect parsing (placeholder at end of list
43 - Fix typos in POD and comments (RT#87776)
44 - Augment -not_bool example with nesting (RT#89601)

53 revision 1.73 2012-07-10

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

272 - fixed semantics of _bindtype on array args
273 - dropped the _anoncopy of the %where tree. No longer necessary.
274 - dropped the _modlogic function
