According to Odaily Planet Daily, the Polkadot community passed Proposal #1143, which will transition from the previous slot auction mechanism to the Agile Coretime mechanism.

Agile Coretime is a new parallel chain resource allocation mechanism that allows projects to rent network computing resources through sales, simplifies the allocation process, improves flexibility, and eliminates the high cost and uncertainty problems in the auction model.

Additionally, in the latest proposal #1161, the community has voted to approve a detailed plan for the Coretime sale, including setting the initial price and sale parameters.
