What's new in Genero Business Development Language, v 2.50

Table 1. Core language
Overview	Reference
Support for character length semantics to simplify UTF-8 programming.	See Length semantics settings.
The UTF-8 character set can be used on Microsoft™ Windows™ platforms by setting the LANG environment variable to `.fglutf8`.	See Language and character set settings.
JSON (JavaScript™ Object Notation) utility classes.	See The util.JSON class, The util.JSONObject class, The util.JSONArray class.
String to `DATETIME` conversion now accepts ISO 8601 format sub-set.	See Data type conversion reference.
The `base.Channel` method `dataAvailable()`, to check for channel readability.	See base.Channel.dataAvailable.
With `IMPORT FGL`, fglcomp now automatically compiles imported modules when needed. To avoid implicit compilation, use the `--implicit=none` option of fglcomp.	See IMPORT FGL module.
The `--resolve-calls` or `-W implicit` fglcomp compiler options can be used to detected unresolved symbols.	See IMPORT FGL module.
The fglrun option `--print-imports` can be used to find modules dependencies and use `IMPORT FGL` instead of traditional linking.	See IMPORT FGL module.

Table 2. User interface
Overview	Reference
Dialog modularization. Declarative `DIALOG` blocks can be defined as module elements and reused with the `SUBDIALOG` keyword of procedural `DIALOG` blocks.	See Structure of a procedural DIALOG block.
Form modularization. Use the new `FORM` layout keyword to include a sub-form in the current form specification file.	See Form file structure.
`CLEAR SCREEN ARRAY` instruction clears the values of all the rows of a form list (`TABLE`, `TREE`, `SCROLLGRID`).	See CLEAR SCREEN ARRAY.
`AUTONEXT` attribute is allowed in `DATEEDIT`, `SPINEDIT` and `TIMEEDIT` fields.	See DATEEDIT, SPINEDIT, TIMEEDIT.
`BUTTONEDIT` item type attribute `NOTEDITABLE`, to disable the field editor.	See NOTEDITABLE attribute.
`ON CHANGE` fired when selecting a date in `DATEEDIT` calendar or when changing the value of a `TIMEEDIT` widget.	See ON CHANGE block.
Presentation style attributes `ringMenuButtonTextHidden` and `actionPanelButtonTextHidden` added to customize the default action view panels.	See actionPanelButtonTextHidden, ringMenuButtonTextHidden.
Presentation style attribute `thinScrollbarDisplayTime` to define the display time of the thin scrollbar when scrolling in fixed screen arrays.	See thinScrollbarDisplayTime
Presentation style attribute `customWidget` to define the widget to be used for a `TEXTEDIT` (and `CHECKBOX` - removed in V3.00).	See TEXTEDIT customWidget.
fglrun options `--start-guilog` and `--run-guilog`, to generate and replay a GUI protocol exchange.	See Front-end protocol logging.

Table 3. SQL databases
Overview	Reference
The SQLite driver `dbmsqt3xx` is now statically linked with the SQLite library, except on platforms where the SQLite library is usually present such as Linux™ and Mac OS-X™.	See the SQLite adaptation guide.
Database driver for PostgreSQL 9.2: `dbmpgs92x`. This driver is similar to the prior PGS 9.x drivers, it is supported for strict binary compatibility with the PostgreSQL 9.2 client library and is compiled with the 9.2 libpq headers.	See Database driver dbmpgs92x.
Database driver for IBM^® DB2^® UDB version 10: `dbmdb2Ax`. This driver is similar to the prior DB2 9.x driver, it is supported for strict binary compatibility with the DB2 10.x client library and is compiled with the 10.x CLI headers.	See Database driver dbmdb2Ax.
Support for the Oracle `RAW` data type, in order to use the `SYS_GUID()` values generator.	See The RAW data type.
`FGLPROFILE` entry for MySQL to specify the my.cnf client configuration file: `dbi.database.dbname.mys.config`.	See Oracle MySQL / MariaDB specific FGLPROFILE parameters.

Table 4. Web Services
Overview	Reference
New security library provides classes and methods to support basic cryptographic features. Although added for Genero Web Services, can be used for any Genero application.	See The security package.
New signature methods in `xml.Signature` class: `signString()` and `verifyString()`.	See xml.Signature methods.
New methods in `xml.CryptoKey`: `loadPublicFromString()` and `savePublicToString()`.	See xml.CryptoKey methods.
Support of Diffie-Hellman key-agreement algorithm. It allows two peers to agree on the same symmetric key, the shared secret, without exchanging confidential data.	See The Diffie-Hellman key agreement algorithm, Supported kind of keys and Computing the shared secret with Diffie-Hellman
HTTP compression support has been added for Genero Web Services.	See HTTP compression.
The `com.HTTPRequest.setAutoReply()` method now works for HTTP HEAD method as well as the GET method.	See com.HTTPRequest methods.
DOM features: The Genero XML DOM library has been enhanced with new features that can be set with the setFeature() method or retrieved with the getFeature() method. `load-save-base64-string` - loads and saves an XML document from/to a base64 string `auto-id-attribute` - sets at document loading all unqualified attributes named ID, id, Id or iD of type ID `auto-id-qualified-attribute` - sets at document loading all qualified attributes named ID, id, Id or iD of type ID `enable-html-compliancy` - allows HTML document parsing and modification using the xml.DomDocument API.	See The DomDocument class.
Binary support on HTTP layer: The Genero COM library has been enhanced to support transport of binary data via the Genero BYTE data type. On the client side, it is now possible to send and read binary data to/from a server with the following two methods: `doRequest()` - sends binary data from a BYTE to a HTTP server `getDataResponse()` - reads binary data from a HTTP server into a BYTE On the server side, it is possible to read and write binary data to a client with following two methods: `readDataRequest()` - reads binary data from a HTTP client into a BYTE `sendDataResponse()` - sends binary data from a BYTE to a HTTP client	See The com package.
Access the HTTP headers request and response in high level web services.	See how to modify your server or use fglwsdl generated global end point at runtime.
The standard API is enhanced with few new methods and a new class called `HTTPPart` to handle the different part in a HTTP request or response at client and server side.	See The HTTPPart class, The HTTPRequest class, The HTTPResponse class, and The HTTPServiceRequest class.
The client side is able to generate stubs to support multiple part with Genero Web Services. Support for the server side is not yet provided. Note: Starting with version 2.50.25, when generating client stubs managing multipart, you will get extra input and/or output variables called `AnyInputParts` and `AnyOutputParts`, defined as a `DYNAMIC ARRAY` of `com.HTTPPart` objects. These arrays may contain additional input and/or output HTTP parts not specified in the WSDL. You will have to adapt your client program, to handle those dynamic arrays in any functions calling such stubs. See Client stubs managing multipart changes.	See Multipart in the client stub and SOAP multipart style requests in GWS.
FGLPROFILE HTTPS configuration details no longer needed to perform HTTPS communication. A default SSL configuration is now generated automatically.	See HTTPS configuration.
Creating URL base that applies to multiple server applications by using a wildcard in the URL, allowing for a shared server configuration (such as authentication and HTTPS).	See Wildcards in the URL base.
