        Important notes (changes that may break existing code)

        ======================================================

 

        * Renamed misspelled TkbmMWInfTNRG64 to TkbmMWInfTRNG64 and ditto for 32 bit.

 

        New stuff

        =========

 

        - Added support for 10.3 Rio.

        - Added properties AutoConvertString:boolean and PrefixedZeroesIsString:boolean to

          TkbmMWONFormat. AutoConvertString controls if the streamer/conversion should

          attempt conversion of string values to native values (default true).

          PrefixedZeroesIsString determines if an all numeric string value with

          prefixed zeroes (eg. 0001 or 00.001) should be considered a string or a

          numeric value (default) upon auto conversion of string values.

        - Added AssignTo to TkbmMWONFormat.

        - Added ClearDateTimeFormatStrings method to TkbmMWONFormat as an easy way

          to clear out already defined date/time format strings.

        - Added DateTime function to TkbmMWONFormat. Returns TDateTime of a TkbmMWDateTime value,

          honoring the settings of property DateTimeStyle. Hence returns UTC or Local date/time

          according to setting.

        - Added HintedValueType to TkbmMWONCustomObject. Is used specially by ON native descendants

          to prefer a specific type upon auto conversion. When setting a value specifically

          using AsInt32 f.ex. the hinted type will also be set to int 32.

        - Added FindParent and FindParentObject to TkbmMWONCustomObject.

        - Added properties IsNumeric, IsString, IsDateTime, IsBoolean to TkbmMWONNative.

        - Added TryAsFmtInt32, TryAsFmtInt64, TryAsFmtVariant, GetAsFmtVariant, SetAsFmtVariant,

          methods to TkbmMWONNative, TkbmMWONObject and TkbmMWONArray. They will use the

          given TkbmMWONFormat instance settings for formatting/parsing the prvided data.

          Basically the Object Notration framework is now very aware about custom formatting if needed.

        - Added SaveToStream and LoadFromStream to TkbmMWBSONMarshal, TkbmMWJSONMarshal, TkbmMWYAMLMarshal.

        - Added SaveToUTF16Stream and LoadFromUTF16Stream to TkbmMWJSONMarshal and TkbmMWYAMLMarshal.

        - Added unit kbmMWConfigONStreamer. Its classes descends from YAML classes and its purpose is

          to allow for configuration interception in various Settings attributes (attributes that takes

          a string containing the settings in a simplified YAML/JSON format). That includes

          kbmMW_Rest, kbmMW_Auth and many others.

        - Added additional hardware based random generator support in unit kbmMWCPUTRNG.

          It contains TkbmMWCPURand32, TkbmMWCPURand64 which both use the CPU's pseudo random generator

          if it exists, and TkbmMWCPUTRNG32 and TkbmMWCPUTRNG64 which both use the CPU's true random noise

          generator if the CPU supports it (Intel/AMD only).

        - Significantly updated TkbmMWCustomMetaData to support a large number of formatter and extractor methods.

        - Updated TkbmMWCustomSQLRewriter to support RewriteUpsert.

        - Added DefaultMetadata property to TkbmMWCustomSQLRewriter. It returns the metadata component that will

          be used if no other metadata instance has been defined for it.

        - Added SchemaName to TkbmMWCustomPooledDataset and TkbmMWCustomResolverTable, and SchemaNameQuote, SchemaNameCase,

          SchemaNameBrackets, QuoteSchemaName to TkbmMWCustomSQLMetaData and in general

          significantly improved support for parsing schema named prefixed values.

        - Improved support for charset in HTTP smart services. By defining

        - Added TkbmMWDateTimeParseOptions to TkbmMWDateTime. The options are used with Parse... and Try...

          methods to instruct how the parsing of date and time strings should be.

          If mwdtpoAllowSimple is not specified ISO8601 times must contain all parts.

          If mwdtpoAllowPartial is not specified ISO8601 and RFC1123 will not allow

            additional information after the date time value.

          if mwdtpoToLocalTZ is specified, it will automatically convert the date/time timezone

            to local timezone. Else the specific timezone given will be used.

        - Added support for %D1 (1 or 2 digit day), %H1 (1 or 2 digit hour), %Z1 (1, 2 or 3 digit

          msecs) which affects value to string conversion.

        - Added TkbmMWPlatformMarshal.Bytes2Stream and TkbmMWDigest128 to kbmMWGlobal.

        - Added kbmMWConditionallyQuoteString, kbmMWSafeIdentifier, kbmMWOccurrences functions

          to kbmMWGlobal.

        - Added support for HTTPSys transports returning RemoteLocation property.

        - Significantly updated HTTP key/value/options handlers in kbmMWHTTPUtils.

        - Added NullOnEmptyString:boolean, Indent:integer, Pretty:boolean to TkbmMWJSONStreamer

          to allow streaming in pretty format.

        - Added OnParseError event to TkbmMWJSONStreamer which is triggered upon a parse error.

        - Added Split(const ACount:integer) Linq method to kbmMWLinq.

        - Added SetFormat to TkbmMWLinq to control format settings for conversion scenarios.

        - Added VALUES syntax to TkbmMWMemSQL. Syntax:

          SELECT * FROM VALUES(xxxx)

          where xxxx is a CSV formatted string, with fields comma separated (,) and

          records semicolon separated (;). kbmMW will autodetect field types based on

          the data.

        - Added a number of SQL functions to TkbmMWMemSQL which can be used in the SQL statement:

          LOCALDATETIMETOISO8601(datetime), ISO8601ToLocalDateTime(string),

          UTCDateTimeToISO8601(datetime), ISO8601ToUTCDateTime(string),

          FormatUTCDateTime([fmt,]datetime), ParseUTCDateTime([fmt,]string)

          FormatLocalDateTime([fmt,]datetime), ParseLocalDateTime([fmt,],string)

          The optional fmt value is a string following the TkbmMWDateTime format strings.

          Eg. '%Y3-%M-%D %H:%N:%S'

        - Added support for marshalling and demarshalling  TTypeKind.tkInt64 and TTypeKind.tkWChar

          in kbmMWObjectMarshal.

        - Added TkbmMemtableWithDefinition which directly descends from TkbmMemTable, but has the

          [kbmMW_Dataset([mwdsfIncludeDefinitions])] to easily force marshalling and demarshalling

          to include dataset definitions (fielddefs etc). Found in kbmMWONMarshal.pas.

        - Added support for automatic marshalling/demarshalling of TkbmMemTable.

        - Added multiple additional query operators to ORM:

          TkbmMWORMQueryOperator = (mwoqoNone,mwoqoIsNull,mwoqoIsNotNull,

            mwoqoEQ,mwoqoLT,mwoqoGT,mwoqoLTEQ,mwoqoGTEQ,mwoqoNEQ,mwoqoLIKE,

            mwoqoEQorNull,mwoqoLTorNull,mwoqoGTorNull,mwoqoLTEQorNull,

            mwoqoGTEQorNull,mwoqoNEQorNull,mwoqoLIKEorNull );

        - Added new source code generator functions to ORM:

          function GenerateDelphiClass(const AValue:TClass;..):string

          function GenerateDelphiClass(const ATable:TkbmMWORMTable;...):string;

          procedure GenerateDelphiClass(const AValue:TClass; var...)

          procedure GenerateDelphiClass(const ATable:TkbmMWORMTable; var...)

          They can be used for generating a Delphi class source for a database table.

          The generated class can be compiled into programs for nromal ORM access.

          Typically used in combination with SurfaceDynamicTable that describes a non ORM

          table for the ORM.

        - Added ImportDBSchema application which can connect to any FireDAC enabled database

          and import a complete schema for the database or specific tables in it and

          generate matching ORM classes.

        - Added support for UPSERT SQL statement which works like an UPDATE or INSERT

          combined statement. If the UPDATE succeeds, no INSERT is made otherwis

          records are INSERTed.

        - Added options to TkbmMWORM.RewriteStatement which controls if the given statement

          should be rewritten to native SQL or to kbmMW SQL.

        - Added support for CRON (Unix type scheduling) strings in kbmMWScheduler.

          kbmMW supports an extra enhanced mode where seconds and years also can

          be specified.

        - Added GroupedAs and Group to IkbmMWScheduledEvent which makes it possible to group

          various events under same name, making it easier to enable or disable

          specific groups of events.

        - Added WithInternalTag and InternalTag to IkbmMWScheduledEvent which allows

          setting a type of tag value within for example arrays of events to

          be fullfilled to forward a value from one event to the next in a chain of events.

        - Added UnScheduleGroup, DeactivateGroup, ActivateGroup methods to TkbmMWScheduler.

        - Added InAMoment methods to TkbmMWScheduler which are perfect for running

          GUI related code asynchronously.

        - Added support for default value in kbmMW_Arg attribute.

          If a smart method is called and the argument is missing, the default value will be used.

        - Added support for ftLargeInt in kbmMWSQLite adapter.

        - Officially announcing new TkbmMWTCPServerTransport which is a very high performance

          transport supporting a very high number of concurrent connections.

          It has been tested primarely on Windows but may support other platforms which it

          will be tested for at a later stage.

 

       Changes/minor additions

        =======================

 

        - Updated AMQP client connection to make ChannelMax and FrameMax properties

          writable.

        - Changed AMQP LastHeartBeat and similar from using ticks to TkbmMWTiming (usecs).

        - Updated several DB adapters that contains a specialized metadata component

          to publish several already existing properties.

        - Updated all Object Notation based streamer classes (JSON,BSON,MessageClass,YAML) to

          support overriding produced ON array, ON object and ON native instances with

          specialized ones, by descending and overriding:

           class function GetNativeClass:TkbmMWONNativeClass;

           class function GetObjectClass:TkbmMWONObjectClass;

           class function GetArrayClass:TkbmMWONArrayClass;

        - Changed FireDAC adapter to not use FireDAC's features for API_MetaList, and instead

          use kbmMW's default rewriter features. Reason is that kbmMW provides more details.

        - Further enhanced TkbmMWRTTI.pas

        - Enhanced TkbmMWSmartClientORM.Persist<T> to allow for additional arguments.

        - Improved null handling in TkbmMWSQLJSONData (kbmMWSQLJSONAPI).

        - Improved disconnection handling in TkbmMWTCPIPIndyClientMessagingTransport.

        - Enhanced DOM XML to and from Object Notation conversion with features for flattening

          arrays only containing one element, and if to treat values with prefixed zeroes

          as a number or as a string.

        - Updated kbmMW socket library.
