+
+### API Changes
+
+The p2p layer was reimplemented as part of the 0.35 release cycle, and
+all reactors were refactored. As part of that work these
+implementations moved into the `internal` package and are no longer
+considered part of the public Go API of tendermint. These packages
+are:
+
+- `p2p`
+- `mempool`
+- `consensus`
+- `statesync`
+- `blockchain`
+- `evidence`
+
+Accordingly, the space `node` package was changed to reduce access to
+tendermint internals: applications that use tendermint as a library
+will need to change to accommodate these changes. Most notably:
+
+- The `Node` type has become internal, and all constructors return a
+  `service.Service` implementation.
+
+- The `node.DefaultNewNode` and `node.NewNode` constructors are no
+  longer exported and have been replaced with `node.New` and
+  `node.NewDefault` which provide more functional interfaces.
+
 ## v0.34.0
 
 **Upgrading to Tendermint 0.34 requires a blockchain restart.**
 This release is not compatible with previous blockchains due to changes to
 the encoding format (see "Protocol Buffers," below) and the block header (see "Blockchain Protocol").
 
-Note also that Tendermint 0.34 also requires Go 1.15 or higher.

This allows the node operator to see only the information they need and the developer to hone in on specific changes they are working on.
 
 ## Configuring Log Levels
 
-
 There are three log levels, `info`, `debug` and `error`. These can be configured either through the command line via  `tendermint start --log-level ""` or within the `config.toml` file.
 
 - `info` Info represents an informational message. It is used to show that modules have started, stopped and how they are functioning.
 - `debug` Debug is used to trace various calls or problems. Debug is used widely throughout a codebase and can lead to overly verbose logging.
-- `error` Error represents something that has gone wrong. An error log can represent a potential problem that can lead to a node halt. 
-
-
-The default setting is a global `main:info,state:info,statesync:info,*:error` level. If you would like to set the log level for a specific module, it can be done in the following format: 
-
-> We are setting all modules to log level `info` and the mempool to `error`. This will log all errors within the mempool module. 
+- `error` Error represents something that has gone wrong. An error log can represent a potential problem that can lead to a node halt.
 
 Within the `config.toml`:
 
 ```toml
 # Output level for logging, including package level options
-log-level = "*:info,mempool:error"
+log-level = "info"
 ```
 
 Via the command line:
