This patch upgrades us to m15. Release notes from m15, as follows:
This patch has a few minor stability fixes, but generally does not change core behavior. Included patches:
- [Patch] We reduce noise to Ethereum JSON-RPC nodes by not requesting full transactions [#378]
- [Patch] We turn on
runtime-debug
for WASM for better logging during the test-net phase [#379]
Note: this supplants the old m15 release that had an incorrect version number.
