Revision history for Sah

0.9.6    2012-10-03 (SHARYANTO)

         [INCOMPATIBLE CHANGES]

         - Remove hash clause 'allow_extra_keys' and replace it with '.restrict'
           attribute for 'keys' clause.

         [NEW FEATURES]

         - Add property: 'prio'.

         - Add HasElems properties: 'elems', 'indices'.

         - Add hash properties: 'keys', 'values'.

         - Add hash clauses: 're_keys', 'allowed_keys', 'allowed_keys_re'.

         [ENHANCEMENTS]

         - Specification for 'req_keys' (previously forgotten to be written).

         - Reorganize FAQ and add some items.


0.9.5    2012-09-26 (SHARYANTO)

         [INCOMPATIBLE CHANGES]

         - Change merge prefix from "[merge]", "[merge+]", etc to
           "merge.normal.", "merge.add.", etc (to be compliant with DefHash)


0.9.4    2012-09-21 (SHARYANTO)

         - Rewrite some parts.

         - Specify types 'all', 'any', 'obj', 'date' (moved from Data::Sah).
           Type 'date' still doesn't have clauses specified yet.

         - Specify clauses for 'hash' and 'array' (moved from Data::Sah)

         - Change examples to use JSON instead of Perl notation.

         - Add FAQ item: comparison to JSON schema.

         - Add FAQ item: advice on writing schemas (preliminary).

         [NEW]

         - Add type: 'undef'.

         - Add attribute: 'input'.

         - Add clauses: 'check_each', 'exists', 'check_exists', 'each_index',
           'check_each_index'.

         [INCOMPATIBLE CHANGES]

         - Rename 'vals' attribute to 'is_multi' (a bool) and store the multiple
           values in the clause value itself. This is to avoid having both
           'CLAUSE' and 'CLAUSE.vals'.

         - Rename 'expr' clause attribute to 'is_expr' (a bool). The expression
           is now contained in the original clause value/attribute. This is to
           be consistent with 'is_multi'.

         - Tweak the 'if' clause (change 'then_ok' or 'else_nok' to 'then' and
           'else').

         - Rename clause 'noop' to 'ok' (consistency with min_ok/max_nok/etc).
           Remove clause 'fail' (can be replaced with '!ok').

         - Rename clause 'check' to 'expr' (consistency with 'prop' as well as
           the 'prop' and 'expr' keys in the 'if' clause).

         [REMOVED]

         - HasElems: remove 'num_of' clause (not generic enough, might be split
           to a custom clause distribution later).


0.9.3    2012-09-20 (SHARYANTO)

         [INCOMPATIBLE CHANGES]

         - BaseType: Rename old 'if' clause to 'if_clause' (the new 'if' clause
           is now a generic condition clause which accepts a hash).

         - HasElems: Rename clause 'all_elems' to 'each_elem'.

         [NEW]

         - Introduce 'result_var' attribute.

         - Introduce 'type property'.

         - BaseType: add clauses 'schema_v' & 'base_v'. Also mention 'defhash_v'
           (from DefHash specification).

         - BaseType: add generic condition clause 'if' (this is different from
           the old 'if', which has been renamed to 'if_clause').

         - BaseType: add generic looping clauses 'each' and 'exists'.

         [FIXED]

         - Move 'elems' clause to array (POD mistake).

         [OTHER]

         - Specify behavior when CLAUSE value and CLAUSE.vals both exist.


0.9.2    2012-09-19 (SHARYANTO)

         - Clause set now uses DefHash.

         - '=' is now a shortcut for '.expr' attribute.

         - Add FAQ and overview (moved from Data::Sah's POD).

         [REMOVED]

         - '.val' removed, now use clause value (DefHash).

         [FIXES]

         - Update some examples.


0.9.1    2012-09-13 (SHARYANTO)

         - Move type documentation from Data::Sah.

         - BaseType: remove clauses 'comment' and add clauses 'v' (DefHash);
           remove implementation clauses (SANITY, PREPROCESS, POSTPROCESS).

         - HasElems: rename clause 'elem_deps' to 'if_elems_re', add clause
           'if_elems'.

         - str: rename clause 'is_regex' to 'is_re'.


0.9.0    2012-07-21 (SHARYANTO)

         First release, split specification from Data-Sah.
