v0.5.18

Release Note

This release contains a wasmer version bump from v2.0.0 to v2.2.1. The wasm caches of these two versions are not compatible, thus rebuilding is required.
To avoid possible sync delays due to the runtime rebuilding overhead, it is highly recommended that node operators rebuild their wasm cache with the cosmwasm-cache-rebuilder before replacing terrad runtime to v0.5.18.

Node upgrade instructions

1. Rebuild your wasm cache using the cosmwasm-cache-rebuilder. This rebuilder can be run simultaneously without killing a running terrad process.
2. You can ignore the file already open error. If other errors occur (no disk space, etc), it is safe to run the rebuilder multiple times.
3. When the rebuilder is finished, update terrad to v0.5.18 and restart.
4. The rebuilder creates a $TERRA_HOME/data/wasm/cache/modules/v3-wasmer1 directory. The $TERRA_HOME/data/wasm/cache/modules/v1 can be deleted after updating terrad to v0.5.18.

Docker Changes
There are major breaking changes in the v0.5.18 version for the docker images.

• The runner now is dedicated terra user not root
• The working directory is also changed to /terra

Additional notes

• 🎉 Wasmer v2.2 supports the much anticipated Apple M1 processor! (See: https://wasmer.io/posts/wasmer-2.2) This means nodes can be run on any arm64 system, such as Apple Silicon machines and AWS Graviton2 Arm64.
