Release 1.11.1

This is a patch release for Vouch with the following bugfix:

• ensure builderclient timeout defaults are set once on startup

This addresses an intermittent issue where vouch failed to start due to concurrent access to the config map.

Notes for multi instance

Multi instance gives the option of running a secondary instance of Vouch with a static-delay. The secondary instance will attempt to perform validator duties if it does not detect another instance performing them. Key considerations:

• You should only attempt to use multi instance if you have slashing protection external to Vouch (e.g. Dirk). A multi instance setup without slashing protection will likely lead to your validators getting slashed.
• You should test your setup thoroughly on testnets before moving to mainnet.
• The static-delay parameters you need to set will be relative to your infrastructure. As a general guide - shorter delays will lead to more duplicate signing attempts; the longer the delay the less likely the secondary will perform duties within the necessary window.
