- If the `--insecure` option is set to `false` and the `HTTPIE_VERIFY_SSL` environment variable is set, we keep its value instead of overwrite it to `yes`.
Useful when we want to use Custom <abbrtitle="Certificate Authority">CA</abbr> (e.g. `HTTPIE_VERIFY_SSL=/etc/ssl/certs/ca-certificates.crt`). For more information, you can read the [HTTPie docs](https://httpie.org/doc/1.0.3#custom-ca-bundle)
- New actions: `ls`, `status`, `services`, `tasks`, `tasks:healthy`, `containers`, `login`, `lint`, `inspect`, `system:info`, `actions`, `help` and `version`
- New options: `--auth-token=[AUTH_TOKEN]`, `--compose-file-base64=[BASE64]`, `--env-file-base64=[BASE64]`, `--timeout=[SECONDS]`, `--detect-job=[true|false]`, `--service=[SERVICE_NAME]`, `--insecure`, `--masked-variables`, `--quiet`, `--lint`, `--help` and `--version`
- New flags: `-A`, `-C`, `-F`, `-G`, `-T`, `-j`, `-i`, `-S`, `-m`, `-q`, `-L`, `-h` and `-V`
- New environment variables: `PORTAINER_AUTH_TOKEN`, `TIMEOUT`, `AUTO_DETECT_JOB`, `PORTAINER_SERVICE_NAME`, `MASKED_VARIABLES`, `QUIET_MODE` and `DOCKER_COMPOSE_LINT`
- The Docker image include now `docker-compose` to be able to lint Docker compose/stack file
- The `core` Docker image variant doesn't include `docker-compose`, so it's a bit smaller. But you can't lint Docker compose/stack file before deploying a stack
- The `debian` and `debian-core` Docker image variants, use [Debian](https://www.debian.org) instead of [Alpine](https://alpinelinux.org/) as base image for `psu`
- Online documentation via [docsify](https://docsify.js.org)
- Tests who run automatically on each git push via [GitLab CI](https://docs.gitlab.com/ce/ci/)
### Changed
- The `undeploy` action is now an aliased action. You should use `rm` action instead
### Deprecated
- The `--secure=[yes|no]` option and `-s` flag are deprecated. Use the `--insecure` option instead (`psu <action> ... --inscure`)
- The `--action=[ACTION_NAME]` option and `-a` flag are deprecated. Use `<action>` argument instead (`psu <action> ...`)
