# 3.50.6
Release Date: August 25, 2023
## **Store Manager**
### Improved landed cost calculations
Starting with release 3.50.6, if you have selected **Use landed cost when receiving merchandise** (and have selected a **Default Cost Distribution Method** of either **Quantity** or **Value**), Store Manager uses improved calculations to calculate the landed cost for each item received through purchase orders and inventory transfers.
Refer to [**Inventory rules**](/store-manager/configure-pos-and-store-manager/inventory-and-purchasing/setting-up-inventory-rules.md) or more information about setting up landed cost. Refer to [**Landed cost**](/store-manager/configure-pos-and-store-manager/inventory-and-purchasing/calculating-landed-cost.md) for more information about the calculations used for landed cost.
## Central Manager
### Control how often the Backwards Compatibility Extension checks for jobs
Starting with release 3.50.6, you can configure how often the Backwards Compatibility Extension checks for jobs in the database. The minimum interval is 10 seconds and the maximum is 60 seconds. Configure the job processing interval to optimize Central Server performance.
To access this configuration option, open **RMH Central Server**, click **Extensions**, and click **Config**.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.rmhpos.com/releases/old/3-50-6.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
