The H3 title is redundant as it repeats the frontmatter title, which is typically rendered by the Hugo template. Consider removing it to avoid double titles in the blog post.

The first feature release of Cozystack lays the groundwork for a production-grade platform.

### Major Features and Improvements

#### ZFS Support

Cozystack now supports **ZFS** as a storage backend, giving operators a choice of battle-tested storage for their infrastructure.

#### Leader Election

Leader election is enabled for the Cozystack controller, ensuring that only one instance is active at a time — a prerequisite for high-availability deployments.

#### Documentation

Project documentation has been moved to [cozystack.io](https://cozystack.io), along with new Adopters, Code of Conduct, Contributing, and Maintainers guides.

#### Other Improvements

- Declarative Redis flush for the dashboard.
- Support for remote Docker builds with `--tar-to-stdout`.
- Installer image renamed from `talos-installer` to `cozystack` to avoid confusion.

All changes: [v0.1.0](https://github.com/cozystack/cozystack/releases/tag/v0.1.0)

Cozystack v0.2: Bundles, Schema Versioning, FluxCD as Core Package, and

heading level (MD001); update that heading token in the markdown (search for the
exact heading text) so the first content heading uses "##" instead of "###",
which will satisfy markdownlint and CI.


Version 0.2 positions Cozystack as a **framework for building clouds** and introduces several foundational changes to the platform architecture.

### Major Features and Improvements

#### Bundle-Based Installation

A new `bundle-name` configuration option (e.g. `paas-full`) allows operators to choose which set of platform components to deploy. This makes Cozystack modular and customizable from the very first installation.

#### Schema Versioning

All `cozy-*` charts now carry explicit version metadata, enabling safe and predictable upgrades across releases.

#### FluxCD Moves to Core

Flux is now installed as a core package, removing the dependency on Helm-based bootstrap and simplifying the installation flow.

#### Component Updates

The version numbers in this post (e.g., LINSTOR v2.4.1) do not match the actual v0.2.0 release history. It appears the AI generator has hallucinated future version numbers. Please cross-reference all feature descriptions and component versions with the official GitHub release notes.

Suggested change
- Piraeus Operator and LINSTOR v2.4.1
- Piraeus Operator v2.2.0 and LINSTOR v1.26.2

- CNPG v1.22.2
- Cilium v1.14.5
- MariaDB Operator v0.27.0
- Kubeapps updated

#### Breaking Changes

This release introduces schema versioning. To upgrade from v0.1.0:
- Create the version configmap: `kubectl create configmap -n cozy-system cozystack-version --from-literal=version=1`
- Add `bundle-name: paas-full` to the Cozystack config.

Use ## for the first in-body heading to fix heading hierarchy.

Line 9 starts at ###, which skips a level and triggers MD001. Change it to ## (and keep deeper sections relative to it) to preserve a valid outline.

unchanged so the document outline remains valid.


Version 0.3 significantly expands the managed application catalog with two major data infrastructure components.

### Major Features and Improvements

#### Kafka

The **Strimzi Kafka Operator** is now included, bringing managed Apache Kafka to the platform. Users can deploy Kafka clusters and manage topics directly from the Cozystack dashboard.

#### ClickHouse

The **ClickHouse Operator** enables deploying managed ClickHouse instances for analytics workloads, with automatic namespace-scoped watching.

#### Hetzner Bare-Metal Support

A new **NoCloud asset** simplifies Cozystack installation on Hetzner dedicated servers, expanding the range of supported infrastructure providers.

#### Other Improvements

- Refactored Makefiles for cleaner build process.
- Fixed Grafana ingress class configuration.
- Fixed kamaji-etcd image tag handling.

The `kamaji-etcd` component is replaced with the new **aenix-io/etcd-operator**, providing better lifecycle management for etcd clusters that back tenant Kubernetes control planes.

#### Replica Configuration

Users can now configure the **number of replicas** for managed applications, giving more control over availability and resource usage.

#### Component Updates

- **LINSTOR** updated to v1.27.1.
- **Kubeapps** updated to v15.0.2.
- **Kamaji** updated to v0.5.0.

#### Fixes

- Automatic tag and version calculation for builds.
- Fixed Flux not tolerating kubectl edits.

Version 0.6 focuses on improving the virtual machine experience and storage management in tenant Kubernetes clusters.

### Major Features and Improvements

#### VM Serial Console

Virtual machines now support **serial console access** via `virtctl` from the KubeVirt toolkit. The root user no longer requires a password, making VM debugging straightforward.

#### Ephemeral Storage for Containers

VMs now launch with **two ephemeral disks** mounted at `/var/lib/containerd` and `/var/lib/kubelet`. This prevents container storage from filling up the root disk — a common issue in long-running clusters.

#### etcd Auto-Quota

The `quota-backend-bytes` for etcd is now **automatically set to 95%** of the space requested by the user, preventing etcd from running out of storage unexpectedly.

⚠️ Potential issue | 🟡 Minor

Fix heading level jump at the post title heading.

Line 9 starts at ###, which skips the expected first content heading level and triggers MD001. Use ## for the top in-body heading, then keep subsections one level deeper.

In `@content/en/blog/2024-05-29-cozystack-v0-7.md` at line 9, The top in-body
heading "Cozystack v0.7: Network Stabilization, DNS Fixes, etcd Autocompaction,
and cozy.local Domain" is using "###" which triggers MD001; change that heading
token from "###" to "##" so the first content heading is level 2 and ensure all
existing subsections under it remain one level deeper (adjust any subsequent
headings if needed) to preserve correct heading hierarchy.


Version 0.7 is a stability release that resolves critical networking issues in tenant Kubernetes clusters.

### Major Features and Improvements

#### Network Stabilization

- Updated **Kube-OVN** to v1.13.0 and **Cilium** to v1.15.5.
- Resolved pod communication issues in tenant Kubernetes clusters by enabling BPF masquerade and tunnel-based routing.
- Fixed **`externalTrafficPolicy: Cluster`** not working correctly.

#### DNS Fixes

Tenant clusters now receive the **correct DNS servers**. The `cluster.local` domain is no longer hardcoded in Kamaji, and a new `cozy.local` domain for the parent cluster enables services to be reached from tenant clusters via a single FQDN.

#### etcd Autocompaction and Defragmentation

Autocompaction and **periodic defragmentation** are now enabled for etcd, keeping storage usage under control and preventing performance degradation over time.

#### PostgreSQL Fix

Fixed incorrect handling of users and roles in the PostgreSQL application configuration.

All changes: [v0.7.0](https://github.com/cozystack/cozystack/releases/tag/v0.7.0)

Fix top-level heading level to avoid MD001.

The first in-body heading should be ##, not ###, to keep heading increments valid.

In `@content/en/blog/2024-07-04-cozystack-v0-8.md` at line 9, Change the first
in-body heading "### Cozystack v0.8: FluxCD Operator, E2E Tests, ARM Support,

"###" with "##") so the top-level in-body heading follows MD001 rules; update
the header text exactly as-is but with "##" to keep heading increments valid.


Cozystack v0.8 is a significant release that overhauls the Flux installation, adds comprehensive testing, and expands platform reach to ARM hardware.

### Major Features and Improvements

#### FluxCD Operator

The installation logic for FluxCD has been completely revamped. The community Helm chart is replaced with the **official FluxCD Operator** (Flux 2.3), providing better lifecycle management and a cleaner upgrade path.

#### E2E Testing

End-to-end tests have been added for robust validation of the platform. This marks the beginning of automated quality assurance for Cozystack releases.

#### ARM Architecture Support

Basic support for **ARM architecture** has been introduced in the `distro-hosted` bundle, broadening the range of hardware Cozystack can run on.

#### Managed Extensions for Tenant Clusters

Users can now install **ingress-nginx**, **cert-manager**, and **FluxCD** in their tenant Kubernetes clusters with a single click in the dashboard. Traffic can also be routed to custom Kubernetes clusters via the primary ingress controller.

#### PostgreSQL Quorum Replication

Synchronous replication based on quorum is now available for the PostgreSQL application, improving data safety for production databases.

#### ETCD Operator v0.3.0

The etcd operator receives a major update with ARM support, an architectural overhaul with detailed flow charts, autocompaction enabled by default, and automatic `quota-backend-bytes` calculation at 95% of PVC size.

All changes: [v0.8.0](https://github.com/cozystack/cozystack/releases/tag/v0.8.0)
