For those who would love to help testing Hermes 0.8.1 before we actually published them to NPM and CocoaPod:

Android

1. download hermes-engine-v0.8.1.tgz from the Github release and install locally.

react-native git/0.65-stable
$ npm install path/to/hermes-engine-vX.Y.Z.tgz 

2. Follow the instructions to build rn-tester on iOS. As for the time this is written, you can run the below commands:

# debug
react-native git/0.65-stable
$ ./gradlew packages:rn-tester:android:app:installHermesDebug
$ ./scripts/packager.sh  # starts Metro

# release
react-native git/0.65-stable
$ ./gradlew packages:rn-tester:android:app:installHermesRelease

iOS

1. crawl an old version of hermes-engine.podspec.json:

react-native git/0.65-stable
$ curl -L -O https://raw.githubusercontent.com/CocoaPods/Specs/master/Specs/5/d/0/hermes-engine/0.7.2/hermes-engine.podspec.json

2. update its version to 0.8.1 and point the http to the new url:

"source": {
    "http": "https://github.com/facebook/hermes/releases/download/v0.8.1/hermes-runtime-darwin-v0.8.1.tar.gz"
},

3. point react_native_pods.rb to the local hermes engine podspec json.

     pod 'hermes-engine', :podspec => '#{prefix}/hermes-engine.podspec.json'

4. Follow the instructions to build rn-tester on iOS. As for the time this is written, you need to run the below command and then open the generated RNTesterPods .xcworkspace in XCode to build it.

react-native/packages/rn-tester
$ USE_HERMES=1 bundle exec pod install  --repo-update
