Release Notes

v5.23.3 on the GitHub

New Features

Project revision tracking in Deployment

Now User can see the deployed revision in Deployment Properties screen for all rule projects

An ability to define runtime context properties in Datatype table

User can mark that datatype field will be used for rules versioning. This should allow to eliminate RuntimeContext as first parameter in all Rule Services using versioning. The old mode is kept for backward compatibility but users are advised to switch to this new feature

Support CORS in Rule Services

CORS is supported for the purpose of integrating with UI clients which can be run on the server other than Rule Services application

Support OpenAPI in RuleServices

OpenAPI Specification (formerly Swagger Specification) is an API description format for REST APIs. OpenAPI v3 is now supported in Rule Services. Swagger v2 specification is now deprecated.

Migration Notes

WebStudio

The setting "Unlimited numbers of copies" will automatically be set to false after migration to this version, and the setting "The maximum count of saved changes for each project:"=100 will be applied. If there is a need to store unlimited amount of changes, set the setting "Unlimited numbers of copies" = true before opening any project. This setting is changed to prevent uncontrolled consumption of free space on HDD/SDD for 'undo' operations during editing a project.

The following properties were changed

BeforeAfter
project.history.count=0 project.history.count=100
project.history.unlimited=true Removed. Use project.history.count=

Rules Service

The following properties were changed

BeforeAfter
ruleservice.aegisbinding.readXsiTypes ruleservice.aegis.readXsiTypes
ruleservice.aegisbinding.writeXsiTypes ruleservice.aegis.writeXsiTypes
ruleservice.aegisbinding.ignoreNamespaces ruleservice.aegis.ignoreNamespaces
ruleservice.deployer.enable ruleservice.deployer.enabled
DISABLED, ENABLED and SMART in ruleservice.jackson.defaultTypingMode JAVA_LANG_OBJECT, OBJECT_AND_NON_CONCRETE, NON_CONCRETE_AND_ARRAYS, NON_FINAL, EVERYTHING, DISABLED. See ObjectMapper
ruleservice.jackson.defaultTypingMode = SMART ruleservice.jackson.defaultTypingMode = JAVA_LANG_OBJECT
