v0.17.0

Changelog

This release includes experimental support for: https://www.diagrams.net/
ℹ️ Please note that this new library won't be available immediately on the public instance https://kroki.io. It might get added once we have enough community support/sponsors to run this additional service as we will need to scale up our infrastructure.

If you are running Kroki on your own infrastructure, you can enable this new service by updating your docker-compose.yml:

version: "3"
services:
  diagramsnet:
    image: yuzutech/kroki-diagramsnet
    expose:
      - "8005"

This release also includes a few bug fixes and contains the latest available versions of:

• BPMN
• Bytefield
• C4 PlantUML
• Excalidraw
• Mermaid
• PlantUML
• Structurizr DSL
• Vega
• WaveDrom

And last but not least, all Docker images now support ARM64, meaning that you can run Kroki on Apple M1.
According to our preliminary tests, all diagram libraries are working fine on Apple M1 except erd because stack (build tool) does not currently support ARM64.

• Set Content-Type on hello page by @MarcelWaldvogel in #1054
• Fixes date-related HTTP headers by @MarcelWaldvogel in #1065

Improvements

• Build yuzutech/kroki-excalidraw, yuzutech/kroki-mermaid, yuzutech/kroki-bpmn and yuzutech/kroki-diagramsnet as multi-arch images to support amd64 and arm64 (Apple M1)
