subscriber: prepare to release 0.2.18 (tokio-rs#1384)

# 0.2.18 (April 30, 2021)

### Deprecated

- Deprecated the `CurrentSpan` type, which is inefficient and largely
  superseded by the `registry` API ([tokio-rs#1321])

### Fixed

- **json**: Invalid JSON emitted for events in spans with no fields
  ([tokio-rs#1333])
- **json**: Missing span data for synthesized new span, exit, and close
  events ([tokio-rs#1334])
- **fmt**: Extra space before log lines when timestamps are disabled
  ([tokio-rs#1355])

### Added

- **env-filter**: Support for filters on spans whose names contain any
  characters other than `{` and `]` ([tokio-rs#1368])

Thanks to @Folyd, and new contributors @akinnane and @aym-v for
contributing to  this release!
