You are reading the documentation for an outdated Corteza release. 2023.9 is the latest stable Corteza release.

Changelog

A changelog page is where we aggregate all the changes for the given release. All releases reside on the same page in reverse chronological order (newer at the top).

The core structure is based on Keep a Changelog.

Index File

The index file recaps major releases, which we were focusing on, such as DAL in the 2022.9 release. The index file is located in the folder, which denotes the version such as 202209/index.adoc.

The index file is structured as follows:
include::ROOT:partial$variables.adoc[]

[#yyyy-mm-x]
= `yyyy.mm`

// Release recap and introduction (sales pitch sort of a thing).

:leveloffset: +1

// Include patch releases ordered by patch number descending (05 -> 04 -> ... -> 00)

:leveloffset: -1

Patch Versions

Patch versions outline the changes that were presented in the given version patch, such as additions, deprecations, and changes.

We now use a tool for the changelog to handle the heavy lifting. Patch releases are described in JSON files inside the src/modules/ROOT/pages/changelog directory (inside the version folder). To exemplify, the 02 patch for the 2022.9 version would be located in the src/modules/ROOT/pages/changelog/202209/02.json file.

The patch release JSON file is structured as follows:
{
  "meta": {
    "releasedOn": "YYYY.MM.DD"
  },

  "added": [],
  "changed": [],
  "deprecated": [],
  "removed": [],
  "fixed": [],
  "security": [],
  "development": []
}
A simple sample with a single changelog entry:
{
  "meta": {
    "releasedOn": "2022.10.20"
  },

  "added": [{
    "what": ["..."],
    "why": ["..."],
    "refs": ["..."]
  }],
  "changed": []
}

You can freely omit unneeded bits from the JSON.

Tips for Better Changelogs

  • avoid ambiguous text, such as Fixed Low Code chart rendering — what was the issue? How was it fixed? Is this the one I was affected by?

  • Try to phrase the changelog entries in a way that describes what the user was facing or what a user could do with it. To exemplify, "Fixed chart legend overflowing onto the chart when a lot of options are presented" instead of Fixed chart legend positioning".
