Welcome to Shopify Community. My name is Olivia and I work here.
Thanks for sharing your question with us. I answered a similar thread that you can find here, where I mention:
While we are not currently accepting new applications, we do hope to launch a new integration for Payment Providers by the second half of 2021.
Please check out the full thread for more context, but I trust this will give you the general timeline that you're looking for.
If any other questions come up please let me know.
Thanks for following up, @janis_janovskis!
We typically share development changes through our announcements blog or our changelog page. Make sure to keep posted with us there, but if you don't hear anything please feel free to connect with our Support team mid-year as well.
