There are no plans for Bitcoin to stop being the anchor chain. Original plans included a sunset for PoX, but that is something the community will decide on, seems like that date will be extended by a lot or eliminated entirely. SIPs and discussions are around that get into this in detail. Ex. https://github.com/blockstack/stacks-blockchain/issues/2613

For details of the technical upgrade, please refer here.

Serendipity has occurred. At the launch of Stacks 2.0, the intent was for 2.1 to automatically go live at Bitcoin block 700,000. However, due to a bug this is not going to happen — the Stacks 2.0 chain will continue indefinitely(see#2507). But, we see this as blessing in disguise. We are strong believers in multi-stakeholder blockchain governance, and we believe that Stackers and miners should also have a say in when and how breaking changes occur — it shouldn’t be just the decision of developers. Therefore, we are going to take this opportunity to make sure that when the 2.1 upgrade is ready, it will only activate with the consent of the network.

Miners are also still in the process of adopting some recent node updates that will help them more reliably prioritize transactions with higher fees. Once those have been adopted thoroughly, this new wallet version should help transactions settle even more reliably.

here’s their github, don’t know exactly where in there the sortition is coded: https://github.com/blockstack/stacks-blockchain

That's the current plan. There's an open issue about whether or not to push it back, make it so users can vote to extend it, or just make it so that STX holders can police miners and make sure they don't discount-mine: https://github.com/blockstack/stacks-blockchain/issues/2613

Clarity also claims decidability. It gives up recursion and restricts looping.

More Clarity Built-ins. There's a growing list of new things to add to Clarity to make it better. For example, there will be a 'tx-sponsor' keyword to indicate the principle who sponsored the transaction; this is not always 'tx-sender'. Also, there will be a 'stx-transfer-memo?' function for transferring STX with a memob(which improves exchange integration), and there will be a 'get-burn-block-info?' function for querying Bitcoin state at any point in the sortition history.
