FEATURE: New `tcpTunnel` backend mode allowing for private sharing of local TCP sockets with other `zrok` users (https://github.com/openziti/zrok/issues/170)
FEATURE: New `udpTunnel` backend mode allowing for private sharing of local UDP sockets with other `zrok` users (https://github.com/openziti/zrok/issues/306)
FEATURE: New metrics infrastructure based on OpenZiti usage events (https://github.com/openziti/zrok/issues/128). See the [v0.4 Metrics Guide](docs/guides/metrics-and-limits/configuring-metrics.md) for more information.
FEATURE: New limits implementation based on the new metrics infrastructure (https://github.com/openziti/zrok/issues/235). See the [v0.4 Limits Guide](docs/guides/metrics-and-limits/configuring-limits.md) for more information.
FEATURE: The invite mechanism has been reworked to improve user experience. The configuration has been moved to the `admin` stanza of the controller configuration and now includes a boolean flag indicating whether or not the instance allows new invitations to be created, and also includes contact details for requesting a new invite. These values are used by the `zrok invite` command to provide a smoother end-user invite experience https://github.com/openziti/zrok/issues/229)
CHANGE: The controller configuration version bumps from `v: 2` to `v: 3` to support all of the new `v0.4` functionality. See the [example ctrl.yml](etc/ctrl.yml) for details on the new configuration.
CHANGE: The underlying database store now utilizes a `deleted` flag on all tables to implement "soft deletes". This was necessary for the new metrics infrastructure, where we need to account for metrics data that arrived after the lifetime of a share or environment; and also we're going to need this for limits, where we need to see historical information about activity in the past (https://github.com/openziti/zrok/issues/262)
CHANGE: `zrok config set apiEndpoint` now validates that the new API endpoint correctly starts with `http://` or `https://` (https://github.com/openziti/zrok/issues/258)
CHANGE: `zrok test loop` has been moved to `zrok test loop public`, making way for additional types of loopback testing tools. The `zrok test endpoint` server now includes an `/echo` endpoint, which provides a simple echo websocket (https://github.com/openziti/zrok/issues/237)
FEATURE: New docker infrastructure, including `docker-compose.yml` examples (and documentation) illustrating how to deploy `zrok` in `docker`-based environments
FEATURE: `zrok controller validate` and `zrok access public validate` will both perform a quick syntax validation on controller and public frontend configuration documents (https://github.com/openziti/zrok/issues/238)
$ zrok controller validate etc/dev.yml
[ERROR]: controller config validation failed (error loading controller config 'etc/dev.yml': field 'maintenance': field 'registration': field 'expiration_timeout': got [bool], expected [time.Duration])
CHANGE: `zrok status` no longer shows secrets (secret token, ziti identity) unless the `--secrets` flag is passed (https://github.com/openziti/zrok/issues/243)
CHANGE: Add configurable "terms of use" link in the controller configuration, and optionally display the link on the login form and registration forms (https://github.com/openziti/zrok/issues/184)
CHANGE: `armv7` builds for Linux are now shipped with releases; these builds were tested against a Raspberry Pi 4 (https://github.com/openziti/zrok/issues/93)
CHANGE: `zrok config set` now includes a warning when the `apiEndpoint` config is changed and an environment is already enabled; the user will not see the change until `zrok disable` is run. The CLI now includes a `zrok config unset` command (https://github.com/openziti/zrok/issues/188)
> This release increments the configuration version from `1` to `2`. See the note below.
CHANGE: The email "from" configuration moved from `registration/email_from` to `email/from`. **NOTE: This change increments the configuration `V` from `1` to `2`.**
CHANGE: Replaced un-salted sha512 password hashing with salted hashing based on Argon2 **NOTE: This version will _invalidate_ all account passwords, and will require all users to use the 'Forgot Password?' function to reset their password.** (https://github.com/openziti/zrok/issues/156)
CHANGE: Switched from `ubuntu-latest` (`22.04`) for the Linux builds to `ubuntu-20.04`. Should improve `glibc` compatibility with older Linux distributions (https://github.com/openziti/zrok/issues/179)
CHANGE: `zrok admin generate` now outputs the generated tokens to `stdout` after successfully provisioning the tokens (https://github.com/openziti/zrok/issues/181)
FEATURE: Allow users to reset their password (https://github.com/openziti/zrok/issues/65)
CHANGE: Improved email styling for new user invite emails (https://github.com/openziti/zrok/issues/157)
CHANGE: Migrated from `openziti-test-kitchen` to `openziti` (https://github.com/openziti/zrok/issues/158).
CHANGE: Show a hint when `zrok invite` fails, indicating that the user should check to see if they need to be using the `--token` flag and token-based invites (https://github.com/openziti/zrok/issues/172).
FIX: Fixed PostgreSQL migration issue where sequences got reset and resulted in primary key collisions on a couple of tables (https://github.com/openziti/zrok/issues/160).
FIX: Remove `frontend` instances when `zrok disable`-ing an environment containing them (https://github.com/openziti/zrok/issues/171)
`v0.3` is a massive elaboration of the concept, pivoting it from being a simple ephemeral reverse proxy solution, to being the beginnings of a comprehensive sharing platform, complete with public and private sharing (built on top of OpenZiti).
`v0.3.0` includes the minimal functionality required to produce an early, preview version of the elaborated `zrok` concept, suitable for both production use at `zrok.io`, and also suitable for private self-hosting.
* DEFECT: Token generation has been improved to use an alphabet consisting of `[a-zA-Z0-9]`. Service token generation continues to use a case-insensitive alphabet consisting of `[a-z0-9]` to be DNS-safe.
