This release removes read & write units from pricing (see the [pricing page](https://clickhouse.com/pricing) for details), updates the ClickHouse version to 22.10, adds support for higher vertical scaling for self-service customers, and improves reliability through better defaults.

<h3 id="general-changes-6">
  General changes
</h3>

* Removed read/write units from the pricing model

<h3 id="configuration-changes-2">
  Configuration changes
</h3>

* The settings `allow_suspicious_low_cardinality_types`, `allow_suspicious_fixed_string_types` and `allow_suspicious_codecs` (default is false) cannot be changed by users anymore for stability reasons.

<h3 id="console-changes-31">

This release significantly lowers compute consumption for small workloads, lowers compute pricing (see [pricing](https://clickhouse.com/pricing) page for details), improves stability through better defaults, and enhances the Billing and Usage views in the ClickHouse Cloud console.

<h3 id="general-changes-7">
  General changes
</h3>

* Reduced minimum service memory allocation to 24G
* Reduced service idle timeout from 30 minutes to 5 minutes

<h3 id="configuration-changes-3">
  Configuration changes
</h3>

* Reduced max\_parts\_in\_total from 100k to 10k. The default value of the `max_parts_in_total` setting for MergeTree tables has been lowered from 100,000 to 10,000. The reason for this change is that we observed that a large number of data parts is likely to cause a slow startup time of services in the cloud. A large number of parts usually indicates a choice of too granular partition key, which is typically done accidentally and should be avoided. The change of default will allow the detection of these cases earlier.

<h3 id="console-changes-32">
  Console changes
</h3>

* Enhanced credit usage details in the Billing view for trial users
* Improved tooltips and help text, and added a link to the pricing page in the Usage view
* Improved workflow when switching options for IP filtering
* Added resend email confirmation button to the cloud console
