Public Testnet release timeframe

I noticed that the testnet is being launched in a closed alpha state. When can I expect the public testnet to go live?

The blog post does mention that the public iteration of the testnet will take place in Q3 2022. Following that, the mainnet is due for the following quarter, Q4 2022 according to the roadmap. Additionally, the open-source code for the Analog SDK will release simultaneously with the mainnet.
