# Release History

***

### V2.1

#### Created: 2026-06-22

Add daily billing events so the plugin is billable MicrosoftExcelPlugin never overrode create\_billing\_events, so it inherited the OmnataPlugin default that returns an empty list. The Sync Engine's nightly CREATE\_BILLING\_EVENTS task therefore produced no charges for this plugin.

* Override create\_billing\_events to emit Omnata's standard daily events via omnata\_standard\_billing\_events(): DAILY\_ACTIVE\_INITIAL for the first billable connection-direction and DAILY\_ACTIVE\_ADDITIONAL for each subsequent one, at $2.00 each.
* Add INITIAL\_CHARGE/ADDITIONAL\_CHARGE Decimal constants and import BillingEventRequest/SnowflakeBillingEvent and Decimal.
* Add src/tier.txt set to "standard"; the engine does not bill (and emits no events for) plugins on the "byo" tier, so this is required for the override to take effect.
* Add CONTEXT.md glossary documenting the billing terms and the tier -> billing-suppression interaction.
* Added billing events

## 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.omnata.com/omnata-product-documentation/omnata-sync-for-snowflake/apps/ms-excel/release-history.md?ask=<question>&goal=<endgoal>
```

`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.
