    View project audit logs permission deprecated

    The view project audit logs permission, project:audit_logs:read, is deprecated and will be sunset on 30 October 2026.

    It has been replaced by the new project:event_logs:read permission. This permission grants the same access to the GET /v1/project/{project}/events endpoint.

    What you need to do

    Use the new permission when granting access to users and groups. Aiven also recommends migrating existing project:audit_logs:read permission. All existing assignments will be migrated to the new project:event_logs:read permission on the sunset date.

      Aiven Console

    Explore your spend in the Aiven Console with billing reports

    The new billing reports help your teams slice organization-wide spend without exporting invoices or checking costs service by service.

    • Current month at a glance: View total costs, billable services, and support charges.
    • Cost explorer: Filter by billing group, cloud provider, project, service name, or service type, pick a time range, and see the total cost and applied credits.
    • Cost trends: See how your spending changes using the daily cost chart, with bar or line view, grouped by billing group, project, service, cloud, or service type.
    • Details of charges: Get specific information on charges with a sortable line-item table, including configurable columns for service, project, cloud, quantity, pricing, and more.

    Billing reports works with the granular billing permissions introduced earlier this year, meaning users don’t need full organization admin rights. Users with the view billing (organization:billing:read) or manage billing (organization:billing:write) permission can view the reports page.

    To start using the billing reports, you may need to enable it: go to your user profile > Feature previews.

      Aiven for Apache Kafka®

    Karapace upgraded to version 6.2.2

    Karapace 6.2.2 expands Schema Registry compatibility and improves reliability and performance.

    New

    • Schema Registry now supports JSON Schema drafts 2019-09 and 2020-12 for validation, storage, and compatibility checks. The unevaluatedProperties, $dynamicRef, $recursiveRef, and $vocabulary keywords are not yet supported.

    Fixed

    • Schema Registry could remain unavailable when the _schemas topic was replicated with Apache Kafka® MirrorMaker 2 and ended with a transaction control record.
    • Avro records with multi-way unions are now decoded up to 6 times faster, reducing REST proxy timeouts.

    For details, see the Karapace 6.2.2 release notes.

    Karapace upgraded to version 6.2.1

    Karapace 6.2.1 improves performance, security, and reliability for your clusters.

    If you use Protobuf schemas with map<K,V> fields in Schema Registry, this release fixes an issue where binary serialization and deserialization didn't preserve the underlying map_entry representation.

    This release also updates the protobuf and confluent-kafka-py dependencies for Schema Registry and Kafka REST proxy.

    For details, see the Karapace 6.2.1 release notes.
