Versioning and Upgrades

Graduation note

When the implementation items below are complete, this doc should be split and graduated:

Move the user-facing content (update mechanism, version pinning, branching) into a new section in docs/readme-setup.md — that’s where users will look for “how do I update Daps?”
Rename this file to docs/developer-versioning.md to cover the maintainer-facing content: semver strategy, release process, distribution options, OSS practices.
Add developer- to the prefix map in dapster/_scripts/sync-docs.mjs and add a Developer sidebar section in dapster/astro.config.mjs.

Context

Daps has no versioning yet: no version number in the CLI, no changelog, no formal update mechanism. This doc establishes the strategy across three areas: versioning Daps itself, how users receive Daps updates, and how users upgrade project dependencies (WordPress, Grist).

Daps versioning

Semantic versioning: MAJOR.MINOR.PATCH

Bump	When
MAJOR	Breaking changes: compose conventions changed, daps.yaml format changed, CLI flags removed, template structure requires migration
MINOR	New workflows, new templates, new flags, image tag bumps in templates — backward compatible
PATCH	Bug fixes, docs, typo fixes, non-behavioral dependency bumps

Starting version: 0.1.0 (pre-release; no stability guarantees).

Single source of truth: <Version>0.1.0</Version> in src/Dapsman.Cli/Dapsman.Cli.csproj. The CLI is the right home — it’s the deployed artifact the user runs. If domain/application libraries were ever published as NuGet packages independently, they’d carry their own versions; for now they’re internals.

Git tag v0.1.0 on Codeberg mirrors the csproj version.

dapsman --version: Prints the version (from Assembly.GetName().Version) and exits. (Not yet implemented — tracked as an implementation item below.)

Changelog: docs/readme-changelog.md — one entry per release, newest first. Each entry: version header, release date, bullet points grouped as Added / Changed / Fixed / Breaking. Synced to dapster.org automatically.

Receiving Daps updates

Current mechanism: git pull

# 1. Check what changed
# (review docs/readme-changelog.md or the Codeberg release notes)

# 2. Pull updates
git pull

# 3. Apply infrastructure changes
dapsman local build

Handling a breaking (MAJOR) update

A MAJOR version bump means something about your project configuration needs to change. The changelog’s migration guide describes exactly what. General process:

Read the migration guide in the changelog
Update your project’s compose files, daps.yaml, or scripts as instructed
dapsman local build

Pinning to a stable version

For users who want stability over getting the latest: checkout a specific release tag and stay there until you’re ready to upgrade.

git checkout v0.2.0

To upgrade to a later version:

git fetch
git checkout v0.3.0
# follow any migration steps in the changelog
dapsman local build

Branching for local customization

Users who modify Daps itself (e.g. to add a private template) should maintain a personal branch based on a release tag:

git checkout -b my-daps v0.2.0
# make local changes

When a new Daps release comes out:

git fetch
git merge v0.3.0   # or rebase
# resolve conflicts — usually minimal, most changes are in src/

Breaking change protocol (developer)

When shipping a MAJOR version bump:

Write a migration guide section in the changelog entry
Add a MIGRATION.md or section in readme-setup.md describing what users need to change
Consider keeping old behavior behind a flag for one MINOR version before removing it

Distribution options

The git-clone approach requires git and some CLI familiarity. For a broader audience, packaged distribution is worth exploring once Daps is stable:

Self-contained binary releases — dotnet publish -r win-x64 --self-contained true produces a single exe with the .NET runtime bundled. Attach platform-specific binaries to Codeberg Releases:

Windows: dapsman-win-x64.exe (zipped)
macOS: dapsman-osx-arm64, dapsman-osx-x64
Linux: dapsman-linux-x64

No .NET installation required. Binary is ~70 MB self-contained. Users update manually by downloading a new release.

Recommendation for now: Self-contained releases is the lowest-effort first step — no runtime dependency, works across platforms, Codeberg already supports release attachments.

Other options for later:

.NET global tool via NuGet (dotnet tool install -g dapsman) — clean UX for users who have .NET installed
macOS: Homebrew tap (brew install louieoc/daps/dapsman)
Windows: MSI installer (WiX or similar)
Linux: apt/snap/AppImage

Upgrading project dependencies

Understanding what lives where

Whether an upgrade goes through the Docker image or through a bind-mounted directory determines how it’s done.

What	Where	How to upgrade
WordPress core	Inside the container image	Update the image tag in the dockerfile, rebuild
WordPress plugins & themes	`wp-content/` (bind-mounted)	WP Admin dashboard
MySQL	Container image	Update tag in compose file, redeploy
Redis	Container image	Update tag in compose file, redeploy

See templates/wordpress/README.md for the step-by-step WordPress core upgrade flow.

Is a template image tag bump a MAJOR or MINOR Daps update?

MINOR. Template updates only affect new projects initialized after the update — existing projects have their own copy of the dockerfile and are not touched. Updating an existing project’s dependency is always the user’s explicit action. No Daps migration needed.

Pinning floating tags

Several templates currently use floating tags (:latest, nginx:alpine) which make upgrades implicit and non-reproducible. Best practice: pin to a specific version and update intentionally.

Template	Service	Current	Better
wordpress	phpmyadmin	`phpmyadmin:latest`	`phpmyadmin:5.2`
astro / static	nginx	`nginx:alpine`	`nginx:1.27-alpine`
grist	grist	`gristlabs/grist:latest`	`gristlabs/grist:1.4`

(Actual versions to confirm at time of pinning.)

Future: upgrade workflow

A dapsman upgrade --project <name> command could compare a project’s image tags against the current template version and suggest updates. Worth adding once Daps has multiple real users.

Open source release practices

Codeberg Releases: create a release per git tag with the changelog entry as release notes; attach self-contained binaries per platform
Pre-release labeling: 0.x.y signals no stability guarantees; cut 1.0.0 once core workflows are stable and tested across multiple real projects
CONTRIBUTING.md: add contributor guidelines before soliciting external PRs

Implementation items

Add <Version>0.1.0</Version> to src/Dapsman.Cli/Dapsman.Cli.csproj
Add dapsman --version command (print Assembly.GetName().Version)
Create docs/readme-changelog.md with an initial 0.1.0 entry
Pin phpmyadmin, nginx, gristlabs/grist to specific versions in templates
Add update instructions and version-pinning guidance to docs/readme-setup.md
Set up Codeberg Releases with self-contained binaries on first release
(Future) dapsman upgrade --project <name> workflow
