###### [v0.9.101](https://github.com/parallelvirtualcluster/pvc/releases/tag/v0.9.101)

  **New Feature**: Adds VM snapshot sending (`vm snapshot send`), VM mirroring (`vm mirror create`), and (offline) mirror promotion (`vm mirror promote`). Permits transferring VM snapshots to remote clusters, individually or repeatedly, and promoting them to active status, for disaster recovery and migration between clusters.
  **Breaking Change**: Migrates the API daemon into Gunicorn when in production mode. Permits more scalable and performant operation of the API. **Requires additional dependency packages on all coordinator nodes** (`gunicorn`, `python3-gunicorn`, `python3-setuptools`); upgrade via `pvc-ansible` is strongly recommended.
  **Enhancement**: Provides whole cluster utilization stats in the cluster status data. Permits better observability into the overall resource utilization of the cluster.
  **Enhancement**: Adds a new storage benchmark format (v2) which includes additional resource utilization statistics. This allows for better evaluation of storage performance impact on the cluster as a whole. The updated format also permits arbitrary benchmark job names for easier parsing and tracking.

  * [API Daemon] Allows scanning of new volumes added manually via other commands
  * [API Daemon/CLI Client] Adds whole cluster utilization statistics to cluster status
  * [API Daemon] Moves production API execution into Gunicorn
  * [API Daemon] Adds a new storage benchmark format (v2) with additional resource tracking

  * [API Daemon] Adds support for the `mirror` VM state used by snapshot mirrors
  * [CLI Client] Fixes several output display bugs in various commands and in Worker task outputs
  * [CLI Client] Improves and shrinks the status progress bar output to support longer messages

  * [API Daemon] Adds support for updating and promoting snapshot mirrors to remote clusters
  * [Node Daemon] Improves timeouts during primary/secondary coordinator transitions to avoid deadlocks
  * [Node Daemon] Improves timeouts during keepalive updates to avoid deadlocks
  * [Node Daemon] Refactors fencing thread structure to ensure a single fencing task per cluster and sequential node fences to avoid potential anomalies (e.g. fencing 2 nodes simultaneously)

###### [v0.9.99](https://github.com/parallelvirtualcluster/pvc/releases/tag/v0.9.99)

  **Deprecation Warning**: `pvc vm backup` commands are now deprecated and will be removed in a future version. Use `pvc vm snapshot` commands instead.
  **Breaking Change**: The on-disk format of VM snapshot exports differs from backup exports, and the PVC autobackup system now leverages these. It is recommended to start fresh with a new tree of backups for `pvc autobackup` for maximum compatibility.
  **Breaking Change**: VM autobackups now run in `pvcworkerd` instead of the CLI client directly, allowing them to be triggerd from any node (or externally). It is important to apply the timer unit changes from the `pvc-ansible` role after upgrading to 0.9.99 to avoid duplicate runs.
  **Usage Note**: VM snapshots are displayed in the `pvc vm list` and `pvc vm info` outputs, not in a unique "list" endpoint.

###### [v0.9.84](https://github.com/parallelvirtualcluster/pvc/releases/tag/v0.9.84)

  **Breaking Changes:** This release features a major reconfiguration to how monitoring and reporting of the cluster health works. Node health plugins now report "faults", as do several other issues which were previously manually checked for in "cluster" daemon library for the "/status" endpoint, from within the Health daemon. These faults are persistent, and under each given identifier can be triggered once and subsequent triggers simply update the "last reported" time. An additional set of API endpoints and commands are added to manage these faults, either by "ack"(nowledging) them (keeping the alert around to be further updated but setting its health delta to 0%), or "delete"ing them (completely removing the fault unless it retriggers), both individually, to (from the CLI) multiple, or all. Cluster health reporting is now done based on these faults instead of anything else, and the default interval for health checks is reduced to 15 seconds to accomodate this. In addition to this, Promethius metrics have been added, along with an example Grafana dashboard, for the PVC cluster itself, as well as a proxy to the Ceph cluster metrics. This release also fixes some bugs in the VM provisioner that were introduced in 0.9.83; these fixes require a **reimport or reconfiguration of any provisioner scripts**; reference the updated examples for details.

  * [All] Adds persistent fault reporting to clusters, replacing the old cluster health calculations.
  * [API Daemon] Adds cluster-level Prometheus metric exporting as well as a Ceph Prometheus proxy to the API.
  * [CLI Client] Improves formatting output of "pvc cluster status".
  * [Node Daemon] Fixes several bugs and enhances the working of the psql health check plugin.
  * [Worker Daemon] Fixes several bugs in the example provisioner scripts, and moves the libvirt_schema library into the daemon common libraries.

###### [v0.9.83](https://github.com/parallelvirtualcluster/pvc/releases/tag/v0.9.83)

  **Breaking Changes:** This release features a breaking change for the daemon config. A new unified "pvc.conf" file is required for all daemons (and the CLI client for Autobackup and API-on-this-host functionality), which will be written by the "pvc" role in the PVC Ansible framework. Using the "update-pvc-daemons" oneshot playbook from PVC Ansible is **required** to update to this release, as it will ensure this file is written to the proper place before deploying the new package versions, and also ensures that the old entires are cleaned up afterwards. In addition, this release fully splits the node worker and health subsystems into discrete daemons ("pvcworkerd" and "pvchealthd") and packages ("pvc-daemon-worker" and "pvc-daemon-health") respectively. The "pvc-daemon-node" package also now depends on both packages, and the "pvc-daemon-api" package can now be reliably used outside of the PVC nodes themselves (for instance, in a VM) without any strange cross-dependency issues.

  * [All] Unifies all daemon (and on-node CLI task) configuration into a "pvc.conf" YAML configuration.
  * [All] Splits the node worker subsystem into a discrete codebase and package ("pvc-daemon-worker"), still named "pvcworkerd".
  * [All] Splits the node health subsystem into a discrete codebase and package ("pvc-daemon-health"), named "pvchealthd".
  * [All] Improves Zookeeper node logging to avoid bugs and to support multiple simultaneous daemon writes.
  * [All] Fixes several bugs in file logging and splits file logs by daemon.
  * [Node Daemon] Improves several log messages to match new standards from Health daemon.
  * [API Daemon] Reworks Celery task routing and handling to move all worker tasks to Worker daemon.

###### [v0.9.82](https://github.com/parallelvirtualcluster/pvc/releases/tag/v0.9.82)

  * [API Daemon] Fixes a bug where the Celery result_backend was not loading properly on Celery <5.2.x (Debian 10/11).

###### [v0.9.81](https://github.com/parallelvirtualcluster/pvc/releases/tag/v0.9.81)

  **Breaking Changes:** This large release features a number of major changes. While these should all be a seamless transition, the behaviour of several commands and the backend system for handling them has changed significantly, along with new dependencies from PVC Ansible. A full cluster configuration update via `pvc.yml` is recommended after installing this version. Redis is replaced with KeyDB on coordinator nodes as a Celery backend; this transition will be handled gracefully by the `pvc-ansible` playbooks, though note that KeyDB will be exposed on the Upstream interface. The Celery worker system is renamed `pvcworkerd`, is now active on all nodes (coordinator and non-coordinator), and is expanded to encompass several commands that previously used a similar, custom setup within the node daemons, including "pvc vm flush-locks" and all "pvc storage osd" tasks. The previously-mentioned CLI commands now all feature "--wait"/"--no-wait" flags, with wait showing a progress bar and status output of the task run. The "pvc cluster task" command can now used for viewing all task types, replacing the previously-custom/specific "pvc provisioner status" command. All example provisioner scripts have been updated to leverage new helper functions in the Celery system; while updating these is optional, an administrator is recommended to do so for optimal log output behaviour.

  * [CLI Client] Fixes "--live" argument handling and duplicate restart prompts.
  * [All] Adds support for multiple OSDs on individual disks (NVMe workloads).
  * [All] Corrects and updates OSD replace, refresh, remove, and add functionality; replace no longer purges.
  * [All] Switches to KeyDB (multi-master) instead of Redis and adds node monitoring plugin.
  * [All] Replaces Zookeeper/Node Daemon-based message passing and task handling with pvcworkerd Celery workers on all nodes; increases worker concurrency to 3 (per node).
  * [All] Moves all task-like functions to Celery and updates existing Celery tasks to use new helpers and ID system.
  * [CLI Client] Adds "--wait/--no-wait" options with progress bars to all Celery-based tasks, "--wait" default; adds a standardized task interface under "pvc cluster task".
  * [Node Daemon] Cleans up the fencing handler and related functions.
  * [Node Daemon] Fixes bugs with VM memory reporting during keepalives.
  * [Node Daemon] Fixes a potential race condition during primary/secondary transition by backgrounding systemctl commands.
  * [API Daemon] Updates example provisioner plugins to use new Celery functions.

###### [v0.9.64](https://github.com/parallelvirtualcluster/pvc/releases/tag/v0.9.64)

  **Breaking Change [CLI]**: The CLI client root commands have been reorganized. The following commands have changed:

   * `pvc cluster` -> `pvc connection` (all subcommands)
   * `pvc task` -> `pvc cluster` (all subcommands)
   * `pvc maintenance` -> `pvc cluster maintenance`
   * `pvc status` -> `pvc cluster status`

Ensure you have updated to the latest version of the PVC Ansible repository before deploying this version or using PVC Ansible oneshot playbooks for management.

  **Breaking Change [CLI]**: The `--restart` option for VM configuration changes now has an explicit `--no-restart` to disable restarting, or a prompt if neither is specified; `--unsafe` no longer bypasses this prompt which was a bug. Applies to most `vm <cmd> set` commands like `vm vcpu set`, `vm memory set`, etc. All instances also feature restart confirmation afterwards, which, if `--restart` is provided, will prompt for confirmation unless `--yes` or `--unsafe` is specified.

  * [CLI] Significantly refactors the CLI client code for consistency and cleanliness
  * [CLI] Implements `-f`/`--format` options for all `list` and `info` commands in a consistent way
  * [CLI] Changes the behaviour of VM modification options with "--restart" to provide a "--no-restart"; defaults to a prompt if neither is specified and ignores the "--unsafe" global entirely
