The Flow network has been upgraded as per the recover plan [here](https://docs.google.com/document/d/1atiNogSnpp6xZkkr7LLSRedVruHIXOqL29YjOpc7WOg).

All nodes ~~**EXCEPT collection nodes**~~ can now be started. (update: **Collection** nodes can also be started)

You can now start your nodes by following [step 1 and 2](https://developers.flow.com/protocol/node-ops/node-operation/network-upgrade#step-1---cleaning-up-previous-spork-state).

Docker image tag: `v0.44.5` (or `v0.44.5-without-adx` or `v0.44.5-without-netgo-without-adx` or `v0.44.5-arm`)

Pull token (non-execution nodes) - `mainnet-28` (same as yesterday)

Pull token for execution node - `mainnet-28-execution` (same as yesterday)

We will follow up with a separate announcement for collection nodes.

Thank you,

Flow Team
