Till now, Kraken CI relied on pretty old versions of Clickhouse and MinIO. In the latest Kraken CI release, both have been upgraded.

Clickhouse has been upgraded from to The migration is seamless from the Kraken CI point of view. There is no need for explicit data migration.

MinIO has been upgraded from RELEASE.2020-12-18T03-27-42Z to RELEASE.2022-10-24T18-35-07Z. The major visible change is the names of environment variables that hold credentials. Previously they were MINIO_ACCESS_KEY and MINIO_SECRET_KEY, now they are MINIO_ROOT_USER and MINIO_ROOT_PASSWORD, respectively. Values of these variables may stay the same; they do not need to be changed.

These changes landed in 0.1091 version.

Kraken Agent can be deployed in multiple ways. Here is presented a new way that leverages Docker Compose. It is not scalable as such agents are run on the same machine but it is quick and simple and if we need just to have one or two more agents this is a way to go.

There is a new way for extending Kraken CI: custom tools. A tool in Kraken CI provides particular functionality that is used in steps in a workflow schema. Till now, there were only built-in tools like git for checking out source code from Git repository, or artifacts for storing or retrieving files from Kraken global storage or finally shell for running commands in a shell.

Custom tools allow for developing such tools by third parties, sharing them with others and installing and using them in Kraken Server.
