| # [v0.2.0](https://github.com/nervosnetwork/ckb/compare/v0.1.0...v0.2.0) (2018-12-17) | ||
|
|
||
| In this release, we have upgraded to Rust 2018. We also did 2 important refactoring: | ||
|
|
||
| - The miner now runs as a separate process. | ||
| - We have revised the VM syscalls according to VM contracts design experiments. | ||
|
|
||

||
| ### BREAKING CHANGES | ||
|
|
||
| * Miner is a separate process now, which must be started to produce new | ||
| blocks. | ||
| * The project now uses Rust 2018 edition, and the stable toolchain has to be | ||
| reinstalled: | ||
|
|
||
| ``` | ||
| rustup self update | ||
| rustup toolchain uninstall stable | ||
| rustup toolchain install stable | ||
| ``` | ||
|
|
||
| If you still cannot compile the project, try to reinstall `rustup`. | ||
