## [Unreleased]

## [3.1.0] - 2021-03-26
### Added
- image labels:
  - `org.opencontainers.image.revision` (git commit hash via build arg)
  - `org.opencontainers.image.source` (repo url)
  - `org.opencontainers.image.title`

## [3.0.0] - 2020-10-10
### Added
- option `NON_ANONYMOUS_SINGLE_HOP_MODE=1` to enable non-anonymous single hop mode
  (direct circuits to introduction & rendezvous points)
- ansible playbook: limit container's cpu usage

### Changed
- healthcheck: probe [network-liveness](https://gitweb.torproject.org/torspec.git/tree/control-spec.txt)
  instead of tcp scanning via socks proxy
- changed log level of `control` domain to `warn`
  (to avoid log spam by healthcheck connecting to control listener)
- added message domains to log messages
- fill `torrc` template with `envsubst`

### Removed
- disabled socks proxy
- `netcat-openbsd` package
  (busybox implementation sufficient for new healthcheck)

## [2.0.0] - 2020-10-01
### Added
- create mount point at `/var/lib/tor`
  to be able to make container's root filesystem read-only

### Changed
- moved tor's data directory from `/home/onion/.tor` to `/var/lib/tor`
- run `tor` as user `tor` (uid=100) instead of `onion` (uid=101)
- docker-compose & ansible-playbook: read-only root filesystem

### Fixed
- docker-compose & ansible-playbook: drop capabilities

## [1.1.0] - 2020-10-01
### Added
- enable [tor control](https://gitweb.torproject.org/torspec.git/tree/control-spec.txt)

  (listening on loopback device only)

### Fixed
- reduced number of image layers

## [1.0.1] - 2020-02-22
### Fixed

### Added
