Revision history for SQL::Abstract
+ - Fix parsing of binary ops to correctly take up only a single LHS
+ element, instead of gobbling up the entire parse-to-date
+ - Explicitly handle ROW_NUMBER() OVER as the snowflake-operator it is
+ - Improve signatures/documentation of is_same_sql_bind / eq_sql_bind
+ - Retire script/format-sql - the utility needs more work to be truly
+ end-user convenient
+
+revision 1.77 2014-01-17
+----------------------------
+ - Reintroduce { -not => undef } column operator (regression from 1.75)
+
+revision 1.75 2013-12-27
+----------------------------
+ - *UPCOMING INCOMPATIBLE BUGFIX*: SQLA used to generate incorrect SQL
+ on undef-containing lists fed to -in and -not_in. An exception will
+ be raised for a while before properly fixing this, to avoid quiet
+ but subtle changes to query results in production
+ - Deprecate and warn when supplying an empty arrayref to like/not_like
+ operators (likely to be removed before 2.0)
+
+ - Warn when using an inequality operator with a multi-value array to
+ arrive at what amounts to a 1=1 condition (no pre-2.0 plans to fix
+ this behavior due to backwards comp concerns)
+ - Fix false negative comparison of ORDER BY <function> ASC
+ - More improvements of incorrect parsing (placeholder at end of list
+ element)
+ - Fix typos in POD and comments (RT#87776)
+ - Augment -not_bool example with nesting (RT#89601)
+
+revision 1.74 2013-06-04
+----------------------------
+ - Fix insufficient parenthesis unroll during operator comparison
+ - 'ORDER BY foo' and 'ORDER BY foo ASC' are now considered equal
+ by default (with a switch to reenable old behavior when necessary)
+ - Change parser to not eagerly slurp RHS expressions it doesn't recognize
+
+revision 1.73 2012-07-10
+----------------------------
+ - Fix parsing of ORDER BY foo + ?
+ - Stop filling in placeholders in `format-sql` since it does not support
+ passing values for them anyway
+ - Fix parsing of NOT EXISTS
+ - Fix over-eager parenthesis unrolling
+ - Fix deep recursion warnings while parsing obnoxiously long sql statements
+ - Fix incorrect comparison of malformed lists
+ - Fix incorrect reporting of mismatch-members in SQLA::Test
+ - Migrate the -ident operator from DBIC into SQLA
+ - Migrate the -value operator from DBIC into SQLA
+
+revision 1.72 2010-12-21
+----------------------------
+ - Extra checks of search arguments for possible SQL injection attacks
+ - Remove excess parentheses in debug SQL
+ - Fix parsing of foo.* in SQLA::Tree
+ - Fix bindtype fail when using -between with arrayrefref literals
+ - Add handling for NULL for -in
+ - The -nest operator has entered semi-deprecated status and has been
+ undocumented. Please do not use it in new code
+
+revision 1.71 2010-11-09
+----------------------------
+ - Add EXECUTING for clarity of long running SQL
+ - Add "squash_repeats" option to fix it such that repeated SQL gets ellided
+ except for placeholders
+ - Highlight transaction keywords
+ - Highlight HAVING
+ - Leave quotes from DBIC in bindargs
+ - Add error checking on "profile" for SQLA::Tree
+ - Hide bulk inserts from DBIx::Class
+ - Fix missing doc (RT#62587)
+ - Format functions in MySQL-friendly manner foo( ... ) vs foo ( ... )
+
+revision 1.69 2010-10-22
+----------------------------
+ - Add quotes for populated placeholders and make the background
+ magenta instead of cyan
+ - Color and indent pagination keywords
+ - Fix a silly bug which broke placeholder fill-in in DBIC
+ - Installs format-sql to format SQL passed in over STDIN
+ - Switch the tokenizer to precompiled regexes (massive speedup)
+ - Rudimentary handling of quotes ( 'WHERE' vs WHERE )
+ - Fix extended argument parsing by IN/BETWEEN
+ - Add proper handling of lists (foo,bar,?)
+ - Better handling of generic -function's during AST construction
+ - Special handle IS NOT? NULL
+ - Make sure unparse() does not destroy a passed in \@bindargs
+ - Support ops with _'s in them (valid in Oracle)
+ - Properly parse both types of default value inserts
+ - Allow { -func => $val } as arguments to UPDATE
+
+revision 1.68 2010-09-16
+----------------------------
+ - Document methods on Tree
+ - Add affordances for color coding placeholders
+ - Change ::Tree::whitespace to whitespace_keyword

+ - Add unindexed DBIx::Class::Storage::PrettyPrinter
+ - Better documentation of undef/NULL in where clause
