Write Simple Table changelog entries and bump package versions. Use when adding a changelog version, writing release notes, upgrading package versions, or when the user mentions changelog, CHANGELOG, or a new release.

12 other projects use a version of this.

The file

We split this skill into the rules it gives an agent

6 rules. 0 are common, 3 are distinctive, and 3 are very specific to this project.

  • 0

    Common

    Most of the 12 edited versions we read keep these.

  • 3

    Distinctive

    This author's own choices. Worth a look.

  • 3

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Read the latest entry and CHANGELOG_ENTRIES at the bottom of changelog.ts.

    line 20
  2. Very specific:

    Add export const vX_Y_Z immediately after the ChangelogEntry type (newest entries stay at the top of the file).

    line 22
  3. Very specific:

    Put vX_Y_Z first in CHANGELOG_ENTRIES.

    line 23
  4. Distinctive:

    Do not invent changes. Only describe what this release actually ships.

    line 26
  5. Distinctive:

    Write for someone who uses the table, not someone who maintains it.

    line 30
  6. Distinctive:

    Do not mention internals: FLIP, WAAPI, compositor, rAF, invert, hold, retarget, virtualization windows, cache hashes, Storybook, or file …

    line 39

“Common” is measured: kept by at least 6 in 10 of the 12 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Write Simple Table changelogs

Changelogs should be plain english, no jargon, concise and should assume little knowledge from the reader.

Where it lives

  • Entries: apps/marketing/src/constants/changelog.ts
  • Versions (keep all six in lockstep): packages/core, packages/react, packages/vue, packages/solid, packages/svelte, packages/angular — package.json "version" only
  • Examples use workspace:*; do not bump them

The changelog page shows version, date, and the changes bullets. Still fill in title and description; they are part of the entry.

Workflow

  1. Read the latest entry and CHANGELOG_ENTRIES at the bottom of changelog.ts.
  2. Choose the next version. Default to the next patch (for example 4.1.6 → 4.1.7) unless the user names a version.
  3. Add export const vX_Y_Z immediately after the ChangelogEntry type (newest entries stay at the top of the file).
  4. Put vX_Y_Z first in CHANGELOG_ENTRIES.
  5. Set date to today (YYYY-MM-DD).
  6. Bump the six package versions to match.
  7. Do not invent changes. Only describe what this release actually ships.

Voice

Write for someone who uses the table, not someone who maintains it.

  • Short sentences. Everyday words.
  • Say what the user can do, or what stopped going wrong.
  • One idea per bullet.
  • The page already prefixes each bullet with New, Improved, Fix, or Breaking. Do not start the description with those words.
  • Prop names are fine when the user sets them (columnReordering, enablePivotPanel).
  • Link a docs page when the change has one.

Do not mention internals: FLIP, WAAPI, compositor, rAF, invert, hold, retarget, virtualization windows, cache hashes, Storybook, or file names.

Shape

export const v4_1_7: ChangelogEntry = {
  version: "4.1.7",
  date: "2026-08-16",
  title: "Short name for the release",
  description: "One sentence: what changed for the person using the table.",
  changes: [
    {
      type: "improvement", // "feature" | "improvement" | "bugfix" | "breaking"
      description: "What the user sees or can do now.",
      link: "/docs/column-reordering", // optional
    },
  ],
};

Pick type from the user's point of view: new thing they can turn on (feature), existing thing that works better (improvement), something that was wrong (bugfix), something they must change in their app (breaking).

Good

From 4.1.6:

You can now build a pivot from the column editor side panel, and multiple row fields show as normal rows instead of nested expand groups.

If you put more than one field in Rows (for example Quarter and Product), the table shows a full row for each pair, not a collapsed group you have to expand.

Bad

From 4.1.2 (too much internals):

@simple-table/angular now builds with ng-packagr (Angular Package Format / partial Ivy). Standalone apps can import SimpleTableComponent without TS-992012.

Rewrite that as: Angular apps can import the table without a compiler error about standalone components.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
