Is version 15.0.2 fully compatible with 11.2.1?

[zilongliang]

Since I recently integrated TAO staking, I found that the previous version didn't work, so I upgraded to version 15.0.2, which supports it. However, I previously implemented token transfers and staking for dot, manta, aca, etc., using version 11.2.1. I want to know if upgrading to version 15.0.2 is fully compatible with the content from 11.2.1. Please help me.

Just based off of Semver, no they would not be compatible because there is 4 MAJOR version changes since 11.2.1.

In addition to that you would have to go through the release notes to see if there is anything that affects your functionality.

Maybe update the API documentation https://polkadot.js.org/docs/api to highlight that it isn't being updated anymore only works up to version 11.x.x?

How many MAJOR version changes before there's a need to update the documentation?

I'm guessing there will be ongoing significant changes until the migration to AssetHub is finished, and that would be a good time to overhaul the documentation?

Yes, I already started to update the types-support metadata so that the docs can have assethub information added when the time comes.

That being said the docs have been up to date for a bit now with the most recent metadata types: polkadot-js/docs#481. The API tab is all correct and up to date, nothing to change there. The only section that would need some additions is the Extension tab which is where a lot of these breaking changes have taken place for external signers.

There is the addition of TransactionExtension but this is not available in any chains at the moment, so there is no point in having docs, there isn't even any signed extensions to use Extrinsic v5.

Not much tbh. PJS api will work the same as it always does. Static types for local development - dynamically generated types at runtime. PJS stays away from the chain specific logic for the most part (with some small exceptions like known types) so things should be gravy.
