Cloud 66 changelog cloud66.com

New

You can now build chained replication topologies across PostgreSQL, MySQL and Redis!

So that means setting up primary → replica → replica instead of fanning every replica off the primary. Setting up a chain is two regular replication operations: enable replication from the primary to the middle server, then enable replication from that middle server to the leaf. The middle server plays both roles simultaneously, and each downstream replica streams from its immediate upstream rather than the root primary.

This takes pressure off busy primaries that today have to feed every replica directly, makes tiered read replicas across regions much easier to lay out, and unblocks topologies that previously needed every replica to compete for bandwidth on a single source. Cloud 66's replication orchestrator now drives each engine's native cascading capability end-to-end, across PostgreSQL, MySQL and Redis.

Update

We're excited to announce that Cloud 66 now natively supports multiple Node.js package managers for classic (Rails/Rack) applications! While it was always possible to use npm, pnpm, or bun via deploy hooks, Cloud 66 now automatically detects and runs the correct package manager for you based on the lockfile in your repository — no additional configuration needed:

• yarn.lock → Yarn (via Corepack)
• bun.lock / bun.lockb → Bun
• pnpm-lock.yaml → pnpm (via Corepack)
• package-lock.json → npm

For new applications (running Node.js 19+) Yarn and pnpm are managed through Corepack, the official Node.js tool for package manager version management. To take full advantage of this, add the standard packageManager field to your package.json (e.g., "packageManager": "yarn@4.1.0") — Corepack will then use that exact version during deployment.

If your repository contains multiple lockfiles (for example during a migration between package managers), Cloud 66 will use the first match in the priority order listed above. We recommend removing unused lockfiles to avoid confusion.

Existing applications are unaffected and will continue to use Yarn installed via apt as before. We'll be rolling this feature out to new servers created gradually — if you'd like it enabled for your applications now, please reach out to our support team!

We are excited to announce Cloud 66 Deploy v3 — a major evolution in how we deploy and manage containerized applications across any cloud.

Deploy v3 has been in development for a long time, and I’m very happy to share the news of its General Availability with all our customers today.

We are rolling out Deploy v3 in phases: starting today, all new accounts will have access to v3, and soon we’ll make it available to all existing customers.

As an Early Access release, all usage of Deploy v3 is currently free.

We can’t wait to see what you build and deploy with Deploy v3, and we’re even more excited to share additional new features with you in the near future.

Improvement

Our product documentation site has a new home! We now have fixed and deterministic page content that can be hardlinked to, a better and more focused search and clear product version and scope visual cues on the site.

In other news, our API documentation has also been updated. The new site has updated content of our latest API and full documentation of our automation webhooks.

New

Announcing the availability of filtering controls for your app default domains. Every application deployed on Cloud 66 is automatically assigned one or more unique default domains under *.c66.me. With this update, you now have control (via your apps traffic filtering configuration) over whether this domain is directly reachable, blocked, or redirected.

By default, these domains are publicly accessible, but this may inadvertently lead to SEO issues if search engines index them. With our new feature, you can decide how web traffic is handled for these default domains. For more information, please check out the help documentation.

New

We're pleased to announce that Cloud 66 now fully supports Rails 8! Included in this support is support for solid_cable, solid_cache and solid_queue components which are now part of the basic generated Rails 8 configuration.

Cloud 66 will now detect when you are using solid_cable, solid_cache and/or solid_queue components in your Rails application. We will then automatically create/configure the additional required logical databases on your database server, as well as bind up your database.yml appropriately too.

Remember that you don't have to use SolidX components; we still make it easy to install/manage Redis & Memcached on your servers, which you may want to keep as the faster alternative.

For more information about this please see our help documentation.

New

We are now very pleased to announce that Ubuntu 24.04 LTS (Noble Numbat) is now supported across all Cloud 66 products. Some of our customers have been waiting for this, and we thank them for their patience!

From this point onward, newly added servers will have Ubuntu 24.04 installed. It is recommended that you use the latest available version when possible.

If you need an older version, you can specify that via your manifest, and with this release, you can now optionally choose the Ubuntu version when scaling up via the UI.

For more on this, check out our blog post!

New

We released Cloud 66 Secrets today! Secrets are stored and transferred encrypted from Cloud 66 to your servers, using a brand new API built for security and are available to your applications as in-memory files.

You can read more about Cloud 66 Secrets on our blog and documentation sites.

Secrets are available from today to all applications and all customers on our new pricing plans.

New

We're excited to announce support for PostgreSQL v17. This update brings a number of cumulative improvements; please see the official release notes for more detail. New PostgreSQL installations will now install v17 by default. You can of course still specify to install an older version via your manifest.

Additionally, PostGIS and pgvector extensions are still installed and enabled by default!
