Version 1.0 was released released 2021-12-01. I’m not sure why no bug was automatically created; monitoring is enabled on the project, and https://release-monitoring.org/project/217041/ knows about the new version.

The upstream changelog[1] says:

> ## 1.0.0
> 
> - Removed
>   - Support for Python 3.6
>   - Positional arguments of `dump` and `dumps` can no longer be passed by keyword.
> - Changed
>   - Revised logic for when the "Array of Tables" syntax will be used.
>     AoT syntax is used when at least one of the tables needs multiple lines, or a single line wider than 100 chars, when rendered inline.
>     A nested structure no longer alone triggers the AoT syntax.
