Muldis::DB
---------------------------------------------------------------------------

2007-07-24   Darren Duncan <perl@DarrenDuncan.net>

    * Muldis::DB version 0.3.0 for Perl 5 is released on CPAN as
    Muldis-DB-0.3.0.tar.gz.  Muldis::DB version 0.3.0 for Perl 6 is not
    released at this time, if ever, since it is currently released only as
    part of the Perl6-Pugs project (in its ext/Muldis-DB/ subdirectory),
    which sets its own less frequent release schedule.  The rest of this
    Changes entry refers only to the Perl 5 version.

    * What was Muldis-DB at version 0.2.0 and earlier, has been split in 2,
    with the parts to be Language-MuldisD and Muldis-DB, each at version
    0.3.0 and later.  Prior to the split, both the Perl 5 and Perl 6
    versions of Muldis-DB contained identical copies of what became
    Language-MuldisD; after the split, neither Muldis-D had a copy.

    * All versioned files had their version numbers brought up to 0.3.0.

    * This release saw no code changes at all.  About half of SeeAlso.pod
    was stripped out, since that stayed only with Language-MuldisD.

    * This is the Muldis-DB-0.3.0 file manifest:

    * Muldis::DB version 0.2.0 for Perl 5 is released on CPAN as
    Muldis-DB-0.2.0.tar.gz.  Muldis::DB version 0.2.0 for Perl 6 is not
    released at all.  The rest of this Changes entry refers only to the
    Perl 5 version, specifically the portions that were not split-off into
    Language-MuldisD following release 0.2.0.

    * Renamed AST.pm to Literal.pm, and split up DB.pm into DB.pod and
    Interface.pm.  Any code that used to be spelled Muldis::DB::AST or
    Muldis::DB is now spelled Muldis::DB::Literal and
    Muldis::DB::Interface.  Following these changes, lib/Muldis/DB.pod is
    still the "main" file for documentation purposes, but for code
    purposes, both Literal.pm and Interface.pm are now used directly.

    * New file versions are: DB.pod and Literal.pm and Interface.pm and
    Language.pod and Validator.pm and Example.pm 0.2.0.

    * Updated Literal.pm to remove all exported functions that trivially
    wrap an object constructor, updated any uses in other files to call
    constructors directly.  Also renamed ::(Bool|Order|Int|Blob|Text)Lit to
    remove the "Lit", and ::(|Quasi)(Tuple|Relation)Sel to remove the
    "Sel", and likewise updated any refs to said.

    * In both Literal.pm and PhysType.pm, renamed any classes named
    (TypeInvo|TypeDict|ExprDict|ValueDict)(|NQ|AQ) to (_\1|\1|Quasi\1)
    respectively, and refs to said.

    * Muldis::DB version 0.1.0 for Perl 5 is released on CPAN as
    Muldis-DB-0.1.0.tar.gz.  Muldis::DB version 0.1.0 for Perl 6 is not
    released at all.  The rest of this Changes entry refers only to the
    Perl 5 version, specifically the portions that were not split-off into
    Language-MuldisD following release 0.2.0.

    * This is a major release that focuses on overhauling or defining part
    of the Muldis D meta-model / system catalog, which is essential for
    supporting any user-defined DBMS entities, that is, for doing anything
    remotely useful.  Said overhaul is expected to be staged over 3-4
    consecutive releases, of which the current one is essentially just
    updating documentation; not much code was changed by this release.

    * New code file versions are: DB.pm and AST.pm and Validator.pm and
    Example.pm 0.1.0.

    * As of this release, all pod-only files now also have version numbers,
    shown in the VERSION docs by NAME, like code-containing modules do; the
    initial version numbers are all 0.1.0.

    * Muldis D now has 2 representation formats (Concrete Muldis D,
    Abstract Muldis D) rather than 3 (relations, ASTs, strings).

    * Updated SeeAlso.pod to remove the proposal for a separately
    distributed Muldis::DB::AST::StringRepr module; instead,
    Muldis::DB::AST will parse and generate Concrete Muldis D by itself.

    * Rearranged any relevant docs and code so that the most important core
    scalar types are now in the order [Bool, Int, Blob, Text] and the
    relation type factory Maybe now appears after Set.

    * Muldis D now has a new scalar data type, "Order", which is an
    enumeration (like "Bool" is) of 3 values: [Increase, Same, Decrease];
    it is the result type of any binary comparison operator that underlies
    the likes of less|greater-than or min|max or sorting operations.  Both
    AST.pm and PhysType.pm were updated to include this type.

    * Muldis::DB version 0.0.1 for Perl 5 is released on CPAN as
    Muldis-DB-0.0.1.tar.gz.  Muldis::DB version 0.0.1 for Perl 6 is not
    released at all.  The rest of this Changes entry refers only to the
    Perl 5 version, specifically the portions that were not split-off into
    Language-MuldisD following release 0.2.0.

    * New code file versions are: DB.pm and AST.pm and Validator.pm and
    Example.pm 0.0.1.

    * The primary purpose of this release is to re-license Muldis::DB under
    actual free software licenses, specifically version 3 of the GPL family
    of licenses, which the Free Software Foundation formally published on
    2007 June 29th.  By contrast, the previous Muldis::DB releases were
    under an expiring proprietary license, with just the promise of a free
    re-license to come.  Accordingly, the file LICENSE/GPL was added to
    this distro, which contains the text of the GPL version 3.0.

    * This release also includes a collection of small documentation
    updates and fixes, such as the following:  We now use the official
    typography for the names 'TTM' and 'D' and such.  Added a DOCUMENTATION
    READING ORDER section to the README file.  Added the 2007 June 4th
    Muldis::DB namespace registration (to the official CPAN module list)
    notice to the Changes file.  Updated parts of DB.pm and Copying.pod
    concerning licensing matters.  This release has no code changes.

    * Muldis::DB version 0.0.0 for Perl 5 is released on CPAN as
    Muldis-DB-0.0.0.tar.gz.  Muldis::DB version 0.0.0 for Perl 6 is not
    released at all.  The rest of this Changes entry refers only to the
    Perl 5 version, specifically the portions that were not split-off into
    Language-MuldisD following release 0.2.0.

    * This is the first release of the Perl 5 Muldis-DB distribution, and
    the first release of any distribution to contain Perl 5 modules named
    Muldis::DB::\w+.

    * This is the initial file manifest:

    * Initial code file versions are: DB.pm and AST.pm and Validator.pm and
    Example.pm and PhysType.pm and Operators.pm 0.0.0.

    * As of this release, Muldis-DB is officially in pre-alpha development
    status.  A lot of documentation and functionality is present, but a lot
    isn't.  What is mostly done is the higher level documentation plus an
    alpha-quality but fundamentally stable public API implementation.  What
    is mostly undone is the reference engine implementation, the test
    suite, and documentation of the API details.  What is already present
    should be sufficient to begin study of Muldis-DB such that it can
    actually be put to use within the next few weeks or months as Muldis-DB
    is fleshed out.  Also, it should be possible now to start writing code
    that uses or extends it.
