Cloudron Release Notes

I used to be quite a big Google Reader fanboy. I had a large RSS collection that I carefully assembled over many years, and Google Reader was the main way I read articles on the internet. It was quite a shock when the service was shut down. I think I was more annoyed that there was nothing I could do but accept the terms set by this big co, which couldn’t care less.

This episode got Johannes and me building Cloudron. A way to run apps on our servers without becoming full-time sysadmins. Ten years on, we have been lucky to build a stable company and a great community that actually cares about self-hosting. Thank you for that!

Now, on to Cloudron 10 already!

Mail server

Mail is the piece of self-hosting people give up on first, given the complexity. Stubborn as we are, we keep investing in it to make it simple. If you think email cannot be reliably self-hosted, give us a try! You will have a working mail server in under 20 mins - batteries included. Most of that time will be spent trying to get an API token for your DNS 😀

In v10, forwarding lives on the mailbox. We also add ARC (Authenticated Received Chain) headers, so forwarded mail can still prove it was genuine.

Relay tokens let apps and scripts send through the server without a mailbox password.

The app story in Cloudron is changing, slowly but surely. Traditionally, app packages were built by the Cloudron team on our build servers, and users simply installed those prebuilt packages from the App Store. Creating a custom package meant installing the Docker Builder app and pushing the result to the Docker Registry app.

With the rise of AI, it is easier than ever to experiment with custom apps and packages. We have made it a priority to simplify deploying and sharing them.

Source builds

In Cloudron 9.1, we made a fundamental change: packages can be built on the server itself, without the Docker Builder. New versions of the CLI default to this server-side workflow (cloudron install / cloudron update upload the source and build there), while still supporting the dedicated builder.

Community App Store

For sharing, we introduced Community packages. Third-party packagers publish a URL that anyone can use to install the package. As with the App Store, community packages pick up updates when the packager releases them.

To help people find those URLs, we launched the Community App Store. This has been an enormous success. Over 89 packages at the time of writing, all published in the last two months! …

We are happy to announce the release of Cloudron 9.2!

For those unaware, Cloudron is a platform that makes it easy to run web apps like WordPress, Nextcloud, GitLab on your server and keep them up-to-date and secure.

Cloudron 9.2 adds a new SCIM addon, MySQL 8.4 and notification emails improvements.

SCIM addon

System for Cross-domain Identity Management API provides user listing access to apps. With this change, apps are immediately aware of all users without requiring users to log in first.

We have implemented SCIM v2. See the documentation for more information.

MySQL 8.4

MySQL 8.0 has reached end of life, and Cloudron now upgrades installations automatically to MySQL 8.4. We have tested all app packages with MySQL 8.4 to ensure compatibility, so the transition is seamless and requires no manual intervention from users.

HTML notification emails

Notification emails now include HTML variants in addition to the existing plain text format, resulting in a more polished and readable experience across mail clients. Email templates can also be tested directly from the “Send test email” button.

Other Notable Changes

• postgresql: remove old vecto.rs extension
• Move configure/admin page link if any into the info view
• dyndns: randomize the cron job that syncs the dns

What’s coming next …

We are happy to announce the release of Cloudron 9.1!

For those unaware, Cloudron is a platform that makes it easy to run web apps like n8n, WordPress, Nextcloud, GitLab on your server and keep them up-to-date and secure.

Notifications view

The notifications panel has been redesigned with read/unread state management.

Notifications view

Two new notifications help you stay on top of updates:

• Automatic app update failure - when an app fails to auto-update (e.g., due to an add-on incompatibility or resource constraint)
• Manual platform and app update required - when Cloudron platform or an installed app has a pending update that requires manual intervention

Let’s Encrypt ARI support

Certificates are renewed automatically based on suggested renewal times provided via ACME Renewal Information (ARI). Benefits of ARI include reducing load spikes at the CA, faster revocation response, and smarter scheduling. Renewals typically occur 1 month before expiry.

Community apps

Third-party developers can now publish app packages independently using a CloudronVersions.json file. Community apps receive automatic updates when the developer publishes new versions. Around 25 community apps are already available.

App store …

We are happy to announce the release of Cloudron 9!

For those unaware, Cloudron is a platform that makes it easy to run web apps like WordPress, Nextcloud, GitLab on your server and keep them up-to-date and secure.

New UI

Cloudron 9 introduces a completely redesigned interface. The new UI is mobile-first by design, working seamlessly across phones, tablets, and desktops.

After a year of development, we've rebuilt the dashboard from the ground up using Vue.js 3.5, replacing 10 years of Angular 1.x code. To power the new interface, we developed Pankow—our open-source component library.

Some screenshots:

Multiple backup sites

Cloudron can now back up to multiple destinations. Each destination, also known as Backup site, can use a different storage provider and schedule. You can also choose what to store on each site - everything, only selected apps or everything except some apps. For example, back up everything to your primary Digital Ocean Spaces bucket daily, while sending some critical apps to a secondary attached disk storage for extra redundancy.

We are happy to announce the release of Cloudron 8.3!

For those unaware, Cloudron is a platform that makes it easy to run web apps like WordPress, Nextcloud, GitLab on your server and keep them up-to-date and secure.

Cloudron 8.3 upgrades the base docker image and provides seamless upgrade of the databases.

New base image

Cloudron apps and addons use an Ubuntu 24.04 LTS based image. The new docker image ID is cloudron/base:5.0.0@sha256:04fd70dbd8ad6149c19de39e35718e024417c3e01dc9c6637eaf4a41ec4e596c. Please update the Dockerfile of your custom apps to use this as the base .

Database upgrades

A core part of Cloudron's self-hosting approach is that users shouldn't have to worry about database choices or database versions that are used by apps. The app packaging mechanism makes the appropriate choices based on the app's preferences.

This release contains many upgrades to the underlying databases and frameworks. The upgrade procedure is entirely transparent and hands-off.

• PostgreSQL is upgraded from v14 to v16
• MySQL is upgraded to v8.0.41
• MongoDB upgraded from v6 to v7
• Redis is upgraded to v7.4
• PHP 8.3 is now the minimum in all apps
• Default node version is 22.14.0 TLS
• Solr, used by mail server for FTS, is upgraded to v9
• Default python is 3.12

We are happy to announce the release of Cloudron 8.2!

For those unaware, Cloudron is a platform that makes it easy to run web apps like WordPress, Nextcloud, GitLab on your server and keep them up-to-date and secure.

Cloudron 8.2 includes support for Sqlite addon, Mail attachment search, OIDC Provider Name Customization, Device Mounts, App Archive, Parallel Tasks, Email notifications, Quay fallback & many bug fixes.

Sqlite Addon

We are seeing more self-hosted applications support Sqlite. Sqlite databases have to be backed up carefully since a simple cp might copy a corrupt database when it's not in WAL mode.

We have added support for Sqlite addon. Like with other databases, Cloudron now takes portable backups of Sqlite databases listed in CloudronManifest.json.

OIDC Provider Name Customization

The Cloudron Name set in the Branding view is now automatically set as the OIDC Provider Name.

App packages can use the new CLOUDRON_OIDC_PROVIDER_NAME environment variable to customize the text of their login buttons. Here's Immich and Grafana making use of the OIDC Provider Name in their login buttons.

Device Mounts …

We are happy to announce the release of Cloudron 8.1!

For those unaware, Cloudron is a platform that makes it easy to run web apps like WordPress, Nextcloud, GitLab on your server and keep them up-to-date and secure.

Cloudron 8.1 includes support for Hetzner Object Storage, Gandi PAT and OpenID Groups. It also fixes regressions in Cloudron 8.

Hetzner Object Storage

Hetzner recently released their S3-Compatible Object Storage . In the Cloudron dashboard, you can choose Hetzner Object Storage as the destination for your backups.

Gandi PAT

Gandi has obsoleted the old API Keys and introduced Personal Access Tokens. Users hosting their domains in Gandi.net are encouraged to move to this new scheme at the earliest. Simple choose the token type as Personal Access Token (PAT) in the Domains view.

OpenID Groups

We have added groups claim in OIDC to convey group membership information for a user. In addition, refresh token support has also been enabled.

Other Notable Changes
