The commit automates several steps so they can be copy-pasted and
executed without any manual adjustments.

On success, it prints a message starting with “SUCCESS:” to make it
easier to distinguish from failures.

It also introduces the CURR_TAG and NEXT_TAG environment variables,
which are used by the automated commands.

-## v1.28.0
-Released: 2025-11-17
-
-- IMPROVEMENT: Deprecated [rolling models](https://docs.victoriametrics.com/anomaly-detection/components/models/#rolling-models) class. Reworked [`RollingQuantileModel`](https://docs.victoriametrics.com/anomaly-detection/components/models/#rolling-quantile) and [`StdModel`](https://docs.victoriametrics.com/anomaly-detection/components/models/#seasonal-trend-decomposition) into [online](https://docs.victoriametrics.com/anomaly-detection/components/models/#online-models) type. Using full class format in config (e.g. `class: model.rolling_quantile.RollingQuantileModel`) is supported for backward compatibility and raises deprecation warnings, however it's recommended to just use alias format (`class: rolling_quantile`) which redirects to the new online version.
-
-- IMPROVEMENT: Added "exact" mode to [Backtesting Scheduler](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/#backtesting-scheduler) to use in combination with "infer every" control for [online models](https://docs.victoriametrics.com/anomaly-detection/components/models/#online-models) such as `mad_online` or `quantile_online`, to provide unbiased estimates of how production scheduler would perform anomaly detection on incoming data streams. In "exact" mode, the model is updated exactly at every "infer every" micro-batch interval, at a cost of increased computation time. See [Backtesting Scheduler](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/#backtesting-scheduler) for details.
-
-- UI: Updated [vmanomaly UI](https://docs.victoriametrics.com/anomaly-detection/ui/) from [v1.1.0](https://docs.victoriametrics.com/anomaly-detection/ui/#v110) to [v1.2.0](https://docs.victoriametrics.com/anomaly-detection/ui/#v120), including dynamic alerting rule and exact mode for [online](https://docs.victoriametrics.com/anomaly-detection/components/models/#online-models) models for production scheduling imitation, see full [release notes](https://docs.victoriametrics.com/anomaly-detection/ui/#v120) for details.

The model will be trained on the last 2 weeks of data each time it is (re)fitted. The model will produce `anomaly_score`, `yhat`, `yhat_lower`, and `yhat_upper` [series](https://docs.victoriametrics.com/anomaly-detection/components/models/#vmanomaly-output) for debugging purposes. The model will be timezone-aware and will use cyclical encoding for the hour of the day and day of the week seasonality.

-## Rebalancing
-
-Every `vminsert` node evenly spreads (shards) incoming data among `vmstorage` nodes specified in the `-storageNode` command-line flag.
-This guarantees even distribution of the ingested data among `vmstorage` nodes. When new `vmstorage` nodes are added to the `-storageNode`
-command-line flag at `vminsert`, then only newly ingested data is distributed evenly among old and new `vmstorage` nodes, while
-historical data remains on the old `vmstorage` nodes. This speeds up data ingestion and querying for the majority of production workloads,
-since newly ingested data is evenly distributed among all the `vmstorage` nodes, while querying is usually performed over recently ingested data,
-which is already stored among all the `vmstorage` nodes. This also provides the following benefits:
-
-- Cluster availability and performance remains stable just after adding new `vmstorage` nodes, since network bandwidth, disk IO and CPU
-  isn't spent on data rebalancing among `vmstorage` nodes.
-- This eliminates all the possible hard-to-troubleshoot failures which may happen during automatic data rebalancing.
-  For example, what happens when some of `vmstorage` nodes become unavailable during data rebalancing?
-  Or what happens if new `vmstorage` nodes are added to the cluster while the previous data rebalancing isn't finished yet?
-- This allows building flexible cluster schemes when distinct subsets of `vminsert` nodes distribute incoming
-  data among different subsets of `vmstorage` nodes with different configs and hardware resources.
-
-There are the following approaches exist for data rebalancing among old and new `vmstorage` nodes:
-
-- To wait until historical data on the old `vmstorage` nodes is automatically deleted according
-  to the configured [retention](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#retention).
-- To pass only new `vmstorage` addresses to `-storageNode` command-line flag at `vminsert` nodes, while passing all the `vmstorage`
-  addresses to `-storageNode` command-line flag at `vmselect` nodes. This enables writing new data only to new `vmstorage` nodes,
-  while historical data from old `vmstorage` nodes remain available for querying via `vmselect` together with the newly ingested data.
-  Then wait until data sizes among old and new `vmstorage` nodes become equal and then add old `vmstorage` nodes the `-storageNode`
-  command-line flag at `vminsert` nodes.

 ## Resource usage limits
 
 By default, cluster components of VictoriaMetrics are tuned for an optimal resource usage under typical workloads.

 It is recommended to set **the same** `-dedup.minScrapeInterval` command-line flag value to both `vmselect` and `vmstorage` nodes
 to ensure query results consistency, even if storage layer didn't complete deduplication yet.
 
-## Metrics Metadata
-
-Cluster version of VictoriaMetrics can store metric metadata (TYPE, HELP, UNIT) {{% available_from "v1.130.0" %}}.
-Metadata ingestion is disabled by default. To enable it, set `-enableMetadata=true` on `vminsert` and `vmagent`.
-
-The metadata is stored in memory and can use up to 1% of available memory by default. The size could be adjusted by `-storage.maxMetadataStorageSize` flag.
-Please note that metadata is lost after `vmstorage` restarts. It is ingested independently from metrics, so a metric may exist without metadata, and vice versa.
-
-Metadata can be queried via the `/select/0/prometheus/api/v1/metadata` endpoint, which provides a response compatible with the Prometheus [metadata API](https://prometheus.io/docs/prometheus/latest/querying/api/#querying-metric-metadata).
-If multiple vmstorage nodes return metadata for the same metric family name, or if multiple tenants have metadata for the same metric family name, vmselect returns only the first matching result. 
-Duplicate metadata entries are not merged or deduplicated across storages or tenants. See [/api/v1/metadata](https://docs.victoriametrics.com/victoriametrics/url-examples/#apiv1metadata) example.
