How to Write Release Notes for Slack

Slack is a different medium — write for it

A Slack release post isn't a changelog and it isn't an email. It's a glanceable heads-up in a busy channel, and it lives or dies in the first line. People skim Slack on their phone between meetings; if your update opens with "We are pleased to announce the following changes," it's already scrolled past.

The job is narrow: tell the team what shipped, why it matters, and who needs to do something — fast enough to read without expanding the message.

The shape that works

1. A bolded one-line headline with the version and the single biggest change. This is the part that shows in notifications.
2. Two to four bullets for the rest — short, result-shaped, one line each.
3. A clear "who needs to act" line if anything requires the team to do something (re-deploy, clear cache, update a config).
4. A link to the full changelog or PR for anyone who wants detail — keep the post itself short and push depth into the thread.

A ready-to-paste example

Here's what that looks like in the channel:

Under 60 words, scannable, and it tells the support team exactly what to brace for. That last line is the difference between a post people read and a post people use.

Formatting tips specific to Slack

• Bold the headline with *asterisks* — Slack renders it, and it anchors the message.
• One emoji, not five. A single :rocket: or :bug: reads as a label; a row of them reads as noise.
• @mention only the people who must act. Mentioning @channel for every release is how a channel gets muted.
• Push detail into the thread. Keep the top message tight; reply with the long version, screenshots, or migration steps.
• Be consistent. Same shape every release means people learn to scan it in two seconds.

Generate the Slack version from your commits

ChangelogAI has a Slack format built for exactly this. Paste your commits, pick Slack, and you get a short, properly formatted post — bold headline, tight bullets, Slack-flavoured markdown — ready to drop in the channel. Generate the GitHub or email version from the same commits in the same session.
