Bor v2.7.1 for Amoy and Mainnet

[deepanshu25R]

Hi everyone,

We have released bor v2.7.1 which contains stability improvements, performance optimisations and some bug fixes.

This release contains EVM optimisations inspired from GEVM. The changes are behind a feature flag and can be enabled by setting --evm-switch-dispatch flag or evm-switch-dispatch = true in config.toml.

Steps for upgrading Bor node

1. Stop bor service

   sudo service bor stop
   
   

2. Install Bor with a version tag, network name (amoy, mainnet), and node type (sentry, validator, or archive).

   # Replace the node type
   curl -L <https://raw.githubusercontent.com/maticnetwork/install/main/bor.sh> | bash -s -- v2.7.1 <network> <node_type>
   
   

3. Check bor version

   /usr/bin/bor version
   
   # It should print 
   # v2.7.1
   
   

4. Restart bor service

   sudo service bor start
