What it means

Who it affects, what changes and what is still unconfirmed

Each sentence links inside to the piece that supports it.

For Solana users and developers watching the network, the immediate takeaway is that the expected September 28 change did not arrive. Anyone looking for a mainnet switch now has to keep following the testing process instead of treating the date as a live deployment moment.

In practice, the network remained on its existing finality setup rather than moving to the new Alpenglow design. That means the faster finality target stayed a described goal, while the public testing stage continued to be the relevant status marker.
