Behavior changes

4D 20 R5

Behavior changes

• The plug-ins 4D Internet Commands and 4D for OCI are no longer included in 4D installers. To get these plug-ins, you need to connect to the 4D Product Download portal.
• Changes made in the Structure editor regarding graphical appearance of tables and fields (color, position, order...) are now saved in a separate file named catalog_editor.json stored in the project's Sources folder.

4D 20 R4

Read What’s new in 4D 20 R4, the blog post that lists all new features and enhancements in 4D 20 R4.

Highlights

• Support of ECDSA encryption format for TLS certificates.
• Client/server and SQL server TLS connections are now configured dynamically (no certificate files are required).
• Direct HTML format for structure definition exports.
• New Code Live Checker that enhances code control during code typing, syntax checking, and compilation steps to prevent execution errors.
• Method parameters declared in #DECLARE prototypes are no longer necessary in "Compiler_" methods.
• Support of custom date and time formats
• New Try(expression) keyword to handle simple error cases.
• New HTTP Parse message command.
• New Non-blocking printing compatibility option.
• New editing mode in the Data Explorer.
• 4D Language commands: What's new page on doc.4d.com.
• 4D Write Pro: What's new page on doc.4d.com.
• Fixed bug list: list of all bugs that have been fixed in 4D 20 R4.

Behavior changes

• Using a legacy syntax for declaring parameters (e.g. C_TEXT($1) or var $1 : Text) is now deprecated and generates warnings at code typing, syntax checking, and compilation steps.
• Selections are now kept consistent after some records have been deleted and others records created (see this blog post.
• In the updated OpenSSL library, the default SSL/TLS security level has been changed from 1 to 2. RSA, DSA and DH keys of 1024 bits and above and less than 2048 bits as well as ECC keys of 160 bits and above and less than 224 bits are now no longer allowed. By default, TLS compression was already disabled in previous OpenSSL versions. At security level 2 it cannot be enabled.
• In order to allow password verification when the 4D user directory uses the bcrypt algorithm, the "password" value in the connectionInfo parameter of the Open datastore command is now sent in clear form by default. Make sure your "On REST authentication" database method can handle passwords in clear form (third parameter is then False) and that Open datastore encrypts your connection by passing the "tls" option to True in connectionInfo. In specific cases, a new "passwordAlgorithm" option can also be used for compatibility (see Open datastore command).

4D 20 R3

Read What’s new in 4D 20 R3, the blog post that lists all new features and enhancements in 4D 20 R3.

Highlights

• New collection.multiSort function.
• Support of context parameter in Formula from string.
• Support of headers property in connectionHandler parameter of 4D.WebSocket.new.
• Global modification stamp to help implementing data synchronization modules. New functions: ds.getGlobalStamp and ds.setGlobalStamp.
• Assigning file references to picture/blob attributes is supported in ORDA.
• Support for initializing the variable's value and data type in the declaration line.
• Log file settings are now saved with the current data file
• New syntax for declaring variadic parameters
• 4D View Pro: Support for the import and export of 4D View Pro documents in Blob format.
• 4D Language commands: What's new page on doc.4d.com.
• 4D Write Pro: What's new page on doc.4d.com.
• Fixed bug list: list of all bugs that have been fixed in 4D 20 R3.

Behavior changes

• Some errors were catchable by your error handling method in interpreted mode only. A fix has been done, so that the following errors will now be caught also in compiled mode: Indice out of range, Type incompatible, and Dereferencing a Null pointer. However, for such errors on Intel processors, the procedure is still interrupted as before, whereas on Apple Silicon processors the procedure is only interrupted if you call the ABORT command.
• 4D no longer includes an internal PHP interpreter. You need to set up and run your own PHP interpreter to use PHP commands.
