Release Notes

Overview

One of the core principles of BevOps is documenting change.

Recipes evolve. Processes improve. Equipment changes. Brewers learn.

Without documentation, it becomes difficult to understand why a beer changed between versions or what contributed to a successful batch.

Release Notes provide a structured way to record those changes.

A release note should clearly communicate:

  • What changed
  • Why it changed
  • What outcome was expected
  • What outcome was observed

The objective is not to create documentation for its own sake.

The objective is to preserve knowledge and make future decisions easier.

Why Release Notes Matter

Imagine brewing a hefeweizen that turns out exactly the way you wanted.

A year later you brew the same beer again and it tastes noticeably different.

Questions immediately arise:

  • Was the recipe changed?
  • Was a different yeast used?
  • Was fermentation handled differently?
  • Was a process improvement introduced?

Without documentation, these answers often rely on memory.

Release Notes transform those assumptions into documented facts.

Relationship to SemFer

Every SemFer version should be accompanied by Release Notes.

SemFer communicates the significance of a change.

Release Notes explain the details of the change.

Example:

Trailhead Wit v1.1.0

SemFer tells us:

This is a minor release.

Release Notes tell us:

Coriander was increased from 0.50 oz to 0.75 oz to improve citrus aroma.

Together they provide a complete history of recipe evolution.

Required Fields

All BevOps Release Notes should include the following information.

Summary

A concise description of what changed.

Example:

Increase coriander addition from 0.50 oz to 0.75 oz.

⸻

Motivation

The reason the change was introduced.

Example:

Enhance citrus character and improve aroma expression.

⸻

Expected Outcome

The anticipated result of the change.

Example:

More expressive nose with improved citrus perception.

⸻

Optional Fields

The following fields are recommended but not required.

Observed Results

What actually happened after deployment and evaluation.

Example:

Orange aroma increased significantly. Coriander became more noticeable but remained balanced.

⸻

Rollback Plan

What action should be taken if the change does not achieve the desired outcome.

Example:

Return coriander addition to 0.50 oz.

⸻

References to any Incident Reports that influenced the release.

Example:

BEV-2026-003 Fermentation temperature exceeded target range.

⸻

Metrics used to validate the change.

Example:

Attenuation Aroma Retention Beer Satisfaction Score

Example Release

Trailhead Wit v1.1.0

Beer: Trailhead Wit Version: v1.1.0 Summary: Increase coriander addition from 0.50 oz to 0.75 oz. Motivation: Enhance citrus aroma. Expected Outcome: More expressive nose and improved citrus character. Observed Results: Pending. Rollback Plan: Return coriander addition to 0.50 oz if spice character becomes excessive.

Release Notes as Brewing History

Over time, Release Notes become more than operational records.

They become the documented history of a beer.

A brewer should be able to review a sequence of Release Notes and understand how a recipe evolved over months or years.

Example:

v1.0.0 Initial production release v1.1.0 Increase coriander addition v1.1.1 Improve wort chilling process v1.2.0 Adjust mash temperature to improve attenuation

Viewed together, these entries tell the story of continuous improvement.

The Goal of Release Notes

The purpose of Release Notes is not documentation.

The purpose of Release Notes is learning.

A successful release should explain why a change was made.

A future brewer should be able to understand the reasoning behind every version of a beer.

If SemFer identifies the version, Release Notes explain the story behind it.

Brew → Iterate → Improve → Enjoy
