HERON

What changed and why

News

Releases of HERON, new features of the builder and of the tools around it, and changes worth knowing before you update. Every release is also listed in the changelog.

Your sites are safe to leave as they are: each one builds with the version range written in its site.yaml until you change it.

What you will find here

Four kinds of news. Each item says what changed, who it affects and whether you need to do anything.

How to update safely

  1. 1

    Read the release

    Check the «Before you update» notes for your version.
  2. 2

    Pull the image

    docker pull ghcr.io/fmstm/heron:prod downloads the latest stable version.
  3. 3

    Change one line

    Widen the range in site.yaml, for example from heron: ">=0.1,<0.2" to the new version.
  4. 4

    Build strictly

    heron build . --env prod --strict. If it stops, the report names the file and what to change.
  5. 5

    Publish

    The same way as always. One site at a time, so the others stay untouched.
