<UseCaseHero title="Weekly Changelog from PRs" description="Compile released PRs into a categorized changelog, post it to Slack, and open a PR to update your docs." prompt="Gather all PRs merged to the release branch this week across our frontend, backend, and mobile repos. Generate a changelog grouped by Features, Bug Fixes, and Improvements. Post it to #releases in Slack and open a PR against the docs repo to update CHANGELOG.md." category="Automations" features="Schedules, Integrations" type="schedule" />

<div className="uc-detail-wrapper">
  <Tip>Don't want to set this up manually? Paste a link to this page into a Devin session and ask it to set everything up for you.</Tip>

  <Steps>
    <Step title="Connect Slack">
      Devin posts the changelog to Slack and opens a PR against your docs repo, so you'll need the Slack integration connected.

      Go to **Settings > Connections > Slack** and connect your workspace. Devin will be able to post messages to any channel it's invited to. Add Devin to the channel you want changelogs posted in (e.g., `#releases`). See the [Slack integration guide](/integrations/slack) for details.
    </Step>

    <Step title="Create the weekly schedule">
      Navigate to **Schedules** in the left sidebar of [app.devin.ai](https://app.devin.ai/?utm_source=docs\&utm_medium=use-case-gallery), or use the **Schedule Devin** option in the input box context menu on the home page. Click **Create schedule** and configure:

      * **Frequency:** Weekly — e.g., every Friday at 4:00 PM UTC
      * **Repositories:** Select the repos Devin should scan for merged PRs
      * **Slack channel:** Select a channel (e.g., `#releases`) so your team sees the changelog when it's ready
      * **Prompt:** Be specific about repos, grouping logic, tone, and output format — and tell Devin to match the style of existing entries in your changelog so the output is consistent week over week

      <PromptBlock type="schedule">
        ```txt Weekly changelog prompt theme={null}
        Gather all PRs merged to the release branch this week across these
        repos:
        - acme/frontend
        - acme/backend
        - acme/mobile

        Only include PRs that made it to the release branch — ignore PRs
        merged to main that haven't been released yet.

        Generate a changelog grouped into these sections, in this order:
        1. **New Features** — PRs with a `feat:` prefix or `feature` label
        2. **Bug Fixes** — PRs with a `fix:` prefix or `bug` label
        3. **Improvements** — performance, refactors, DX improvements
           (anything that isn't a feature, fix, or chore)

        Skip PRs labeled `internal` or `chore`.

        For each entry:
        - Lead with a short, user-facing title (not the raw PR title)
        - Follow with a one-sentence summary of what changed and why
        - Include the PR number and author handle
        - Keep the tone concise and factual — no marketing language

        Read the existing entries in CHANGELOG.md in the acme/docs repo
        and match their heading style, bullet format, and level of detail
        exactly.

        Post the result to #releases in Slack and open a PR against the
        acme/docs repo to prepend the new section to CHANGELOG.md.
        ```
      </PromptBlock>

      Devin scans each repo for PRs merged in the past 7 days, reads their titles, descriptions, and labels to categorize them, then generates output like this:

      ```markdown theme={null}
      # Changelog — Week of Feb 14, 2026

      ## New Features
      - **User profile avatars** — Upload custom avatars from the settings page (#412, @alice)
      - **CSV export for analytics** — Export any dashboard chart as CSV (#398, @bob)

      ## Bug Fixes
      - **Date picker timezone** — Fixed UTC offset in booking flow (#419, @carol)
      - **iOS nav overlap** — Resolved navbar covering content on Safari (#421, @dave)

      ## Improvements
      - **API rate limiting** — Per-key rate limits on webhook endpoints (#210, @bob)
      - **Search performance** — Full-text search 3x faster on large datasets (#405, @alice)
      ```
    </Step>

    <Step title="Tailor it to your audience">
      The same schedule can produce different outputs depending on who reads the changelog. Add [Knowledge](/product-guides/knowledge) entries to teach Devin your team's conventions, or adjust the prompt for different audiences.

      **For internal engineering teams** — include PR numbers, author handles, and links to the PRs. Mention infrastructure changes and internal tooling updates.

      **For user-facing release notes** — strip technical details, rewrite in plain language, and skip internal changes entirely:

      <PromptBlock>
        ```txt User-facing release notes theme={null}
        Rewrite this week's changelog for customers. Only include PRs that
        made it to the release branch. Remove anything internal. Use
        non-technical language — focus on what users can now do, not how
        it was built. Post to #product-updates in Slack instead of #releases.
        ```
      </PromptBlock>
    </Step>
  </Steps>
