+
+## Deprecation notes
+
+- The new entrypoint to run the Bor client is ```server```.
+
+```
+$ bor server
+```
+
+- Toml files to configure nodes are being deprecated. Currently, we only allow for static and trusted nodes to be configured using toml files.
+
+```
+$ bor server --config ./legacy.toml
+```
+
+- Modules, vhost and Cors configuration are common for all jsonrpc endpoints.
+
+Before:
+
+```
+$ bor --http --http.modules "eth,web" --ws --ws.modules "eth,web"
+```
+
+Now: 
+
+```
+$ bor server --http --ws --jsonrpc.modules "eth,web"
+```
+
+- ```Admin```, ```Personal``` and account related endpoints in ```Eth``` are being removed from the JsonRPC interface. Some of this functionality will be moved to the new GRPC server for operational tasks.
