Salesforce Marketo Sales Insight app release notes

I reached out to Marketo support with few question related to Salesforce lightning compatibility and they suggested me to post my question here

Marketo support suggested us to upgrade Marketo sales insight app from 1.4343 to 1.4359.2. But before upgrading package, we want to understand new feature or fixes introduced in between. As Marketo Sales Insight is not available on AppExchange finding this information is difficult.

Can you please help us understand what are feature or fixes introduce in between.
