  • #4283 Fix for OIDC provider access token verification. For OIDC provider, accessTokenIsJwt config property is introduced, with default values false. This change also introduced a possibility to override username incoming from OIDC provider. For more see usersFile configuration. This might be helpful when other systems authenticate in Nussknacker in machine to machine manner.
  • #4246 Store components usages along with scenario json. Components usages by a scenario are stored in the processes version table. It allows to speed up fetching components usages across all scenarios, especially for a big number of scenarios and each with a lot of nodes.
  • #4254 Add simple spel expression suggestions endpoint to BE
  • #4323 Improved code suggestions with Typer
  • #4406 backendCodeSuggestions set to true, so by default Nussknacker will use new suggestion mechanism

  • #4360 Fix for spel validations: Typing type reference with class starting from lower case e.g. T(foo) caused nasty error
  • #4357 Refactoring of scenario properties required by DeploymentManager (TypeSpecificData) -
    they are now derived from ProcessAdditionalFields and are configured in additionalPropertiesConfig in DeploymentManagerProvider

1.9.1 (24 Apr 2023)​

  • #4243 Fix for: Scenario status remain "in-progress" after attempt of deploy of not validating scenario

1.9.0 (21 Apr 2023)​

  • #4055 Performance tweaks for API operations like: process status, deploy, cancel
  • #3675 Improvements: Normalize kafka params name
  • #4101 Notifications fixes:
    • Scenario state wasn't refreshed after deploy/cancel action was successfully finished (was only after failure)
    • Notification "Deployment of ... failed ..." was presented even for cancel action
  • #4102 Flink deploy now wait until job is started on TaskManagers before reporting that is finished - thanks to that status and versions panel are refreshed with "DEPLOYED" state in the same time
  • #3992 Fix for compiling scenarios containing filter node with only 'false' edge
  • #4127 ResourceLoader and bumps commons io 2.4 -> to 2.6
  • #4122, #4132, #4179, #4189
    • Add state definitions to ProcessStateDefinitionManager
    • Add StatusResources endpoint /statusDefinitions that returns state definitions with default state properties (such as displayable name, icon and description), to allow filtering by state in UI.
    • Combine statuses Failing, Failed, Error, Warning, FailedToGet and MulipleJobsRunning into one status that represents a "Problem". Statuses FailedStateStatus and "Unknown" are removed.
    • Status configuration for icon, tooltip and description is obligatory.
  • #4100, #4104, #4150 Before the change, the scenario list for a moment presented "local" states - based only on Nussknacker's actions log. After the change, we always present state is based on engine (e.g. Flink) state - in some places like scenario list, it is cached.
  • #4131 Support for components using other languages than SpEL, added basic support for SpEL in template mode
  • #4135 Added timeout configuration for fetching scenario state and bumps skuber 3.0.2 -> 3.0.5

  • #4160 Testing using events from file accepts simplified test record format. SourceId and timestamp fields can be omitted from the test record and record field can be inlined. The simplified format works only for scenarios with only one source.
  • #4161 Update most dependencies to latest versions
  • #4155 Stop adding response header 'cache-control: max-age=0'. Akka adds correct 'etag' and 'last-modified' headers, hence caching is secure.
  • #4117#4202 Fragment parameters definition is now computed based on config. Thanks to that you can use componentsUiConfig setting to provide additional settings like parameter's validators or editors to fragments.
  • #4201 Fix for: Dynamic nodes (GenericNodeTransformation) has now initial parameters inferred based on definition instead empty List
  • #4224 Fix for (de)serialization of Flink state when using NU with Scala 2.13. See MigrationGuide for details.
