-1. Prefer setting [requests equal to limits](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/#requests-and-limits)
-for stateful components like [vmstorage](https://docs.victoriametrics.com/cluster-victoriametrics/#architecture-overview) to avoid unnecessary
-component restarts.
-
-1. Avoid using [fractional CPU units](https://kubernetes.io/docs/tasks/configure-pod-container/assign-cpu-resource/#cpu-units) 
-when setting resources for optimal performance. VictoriaMetrics is written in Go and its runtime requires specifying
-[integer number](https://pkg.go.dev/runtime#GOMAXPROCS) of concurrently running threads. 
-When fractional CPU unit is specified, VictoriaMetrics will automatically round it down.

 ## Security

 Please find the changelog for VictoriaMetrics Anomaly Detection below.
 
-## v1.19.2
-Released: 2025-01-27
-
-- IMPROVEMENT: Added the `complete` option to the `--splitBy` argument in `config_splitter.py` [util](https://docs.victoriametrics.com/anomaly-detection/faq/#splitting-the-config). This allows splitting a parent configuration into the smallest possible sub-configurations, each containing exactly one scheduler, one model, and either one or multiple queries (depending on whether the model is [multivariate](https://docs.victoriametrics.com/anomaly-detection/components/models/#multivariate-models) or not).
-
-- FIX: Resolved an issue where duplicate log messages were generated during sub-config validation of the parent configuration.
-
-- FIX: Corrected usage of `AccountID` and `ProjectID` extracted from `tenant_id`, which are appended as labels `vm_account_id` and `vm_project_id`, respectively (previously swapped) by `VmReader` when using the per-query `tenant_id` feature. **This issue affected versions [v1.19.0](#v1190) and [v1.19.1](#v1191).**
-
-- FIX: Resolved an issue with the `VmReader` instance string representation that caused errors when `vmanomaly` was run with `--loggerLevel DEBUG`.
-
 ## v1.19.1
 Released: 2025-01-21
 
-> **Note**: There is a known bug in [v1.19.0](#v1190) - the `AccountID` and `ProjectID` are swapped when they are extracted from the `tenant_id` argument in `VMReader`. This can cause correctly read results being written to the wrong tenant when using the per-query `tenant_id` feature with `AccountID` != `ProjectID`. Please update to patch [v1.19.2](#v1192), which resolves this issue.
-
 - FIX: Resolved writer warnings for configurations where `reader.tenant_id` equals `writer.tenant_id` and **is not** `multitenant`, as this is a valid setup. Enhanced tenant_id-related log messages across config validation, reader, and writer for improved clarity.
 
 ## v1.19.0
 Released: 2025-01-20
 
-> **Note**: There is a known bug in [v1.19.0](#v1190) - the `AccountID` and `ProjectID` are swapped when they are extracted from the `tenant_id` argument in `VMReader`. This can cause correctly read results being written to the wrong tenant when using the per-query `tenant_id` feature with `AccountID` != `ProjectID`. Please update to patch [v1.19.2](#v1192), which resolves this issue.
-
 - FEATURE: Added support for per-query `tenant_id` in the [`VmReader`](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader). This allows overriding the reader-level `tenant_id` within a single global `vmanomaly` configuration on a *per-query* basis, enabling isolation of data for different tenants in separate queries when querying the [VictoriaMetrics cluster version](https://docs.victoriametrics.com/cluster-victoriametrics/). For details, see the [documentation](https://docs.victoriametrics.com/anomaly-detection/components/reader/?highlight=tenant_id#per-query-parameters).

 - IMPROVEMENT: Accelerated performance of model fitting stages on multicore systems.
 - IMPROVEMENT: Optimized query handling in multi-[scheduler](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/) setups by filtering [queries](https://docs.victoriametrics.com/anomaly-detection/components/models/#queries) for each scheduler based on model requirements. This reduces unnecessary data fetching from VictoriaMetrics, ensuring only relevant queries are processed by the [VmReader](https://docs.victoriametrics.com/anomaly-detection/components/reader#vm-reader), leading to better performance and efficiency of configs with multiple active schedulers.
 
-- IMPROVEMENT: Implemented automatic cleanup of files in subdirectories within `/tmp` ([generated by the Stan backend](https://mc-stan.org/cmdstanpy/users-guide/outputs) when utilizing [Prophet](https://docs.victoriametrics.com/anomaly-detection/components/models/#prophet) models) after each `fit` operation. This prevents the accumulation of unused data over time in `/tmp`, addressing a potential issue where these files would only be deleted upon termination of the current Python session or service, leading to uncontrolled disk growth.

-**Update note 1: [Single-node VictoriaMetrics](https://docs.victoriametrics.com/) and  [vmstorage](https://docs.victoriametrics.com/victoriametrics/) stop exposing `vm_index_search_duration_seconds` histogram metric. This metric records time spent on search operations in the index. It was introduced in [v1.56.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v1.56.0). However, this metric was used neither in dashboards nor in alerting rules. It also has high cardinality because index search operations latency can differ by 3 orders of magnitude. Hence, dropping it as unused.**
-
-* FEATURE: [Single-node VictoriaMetrics](https://docs.victoriametrics.com/) and [vmstorage](https://docs.victoriametrics.com/cluster-victoriametrics/): improve startup times when opening a storage with the [retention](https://docs.victoriametrics.com/#retention) exceeding a few months.
-* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add the ability to switch the heatmap to a line chart. Now, vmui would suggest to switch to line graph display if heatmap can't be properly rendered. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/8057).
-* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth/): add `-httpInternalListenAddr` cmd-line flag to serve internal HTTP routes `/metrics`, `/flags`, etc. It allows properly route requests to backends with the same service routes as vmauth. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6468) and [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7345) for details.
-* FEATURE: expose `/-/healthy` and `/-/ready` endpoints as Prometheus does on vmselect endpoints, thus achieving full Prometheus compatibility for external dependencies.
