Plume support
This release adds support for Plume mainnet and testnet. To enable it on mainnet, please use the following config parameters:

--plumeRPC      YOUR_WEBSOCKET_RPC
--plumeContract 0xaBf89de706B583424328B54dD05a8fC986750Da8

Governor changes

• This release reduces the governor limits for Blast and X Layer to 0, delaying all token bridge transfers originating from those chains by 24 hours. This is due to extremely low cross-chain activity over Wormhole and preparation for a possible disconnection.
• The maximum time a governor delay can be extended to manually via the admin command has been increased from 7 to 30 days.

Note: versions v2.36.0 and v2.37.0 were not proposed to mainnet guardians. The changelog for these are copied in this release note.
