At present, API definitions are validated against the default OpenAPI schema upon import and when being edited in the publisher portal. In certain scenarios, such as the validation of fields like email or name, a custom validation approach may be required. This implementation allows administrators to enforce custom rules for API validation, helping to standardize and keep API definitions clean by validating against a specified set of custom rules inside WSO2 API Manager.

WSO2 APICTL allows users to perform API related tasks without any UI navigations. As an improvement, now WSO2 APICTL allows users to do common API Policy and Rate Limiting Policy related operations without any UI accesses and accelerates the CI/CD tasks related to the Policy Management. From this feature, it now allows to list, export, import and delete operations on both the common API Policies and Rate Limiting policies in multiple ways in accordance with the commands & their flags introduced.

Tracing is one of the three pillars of observability. Tracing artifacts of WSO2 Micro Integrator is important to observe, identify possible bottlenecks in a message flow, and debug them. WSO2 Micro Integrator facilitates tracing message flows and publishing the traces based on the OpenTelemetry standard, using multiple tracers, namely: OpenTelemetry Protocol (OTLP), Jaeger, Zipkin, Log & Custom Tracer. This screencast outlines important concepts of OpenTelemetry based distributed tracing in WSO2 Micro Integrator, followed by a demonstration of publishing traces using the OTLP Tracer to New Relic APM, when invoking a simple API.
