# v0.3.0-rc3 (WiP) > 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) FIX: Fixed log message in `resetPasswordRequest.go` (https://github.com/openziti/zrok/issues/175) # v0.3.0-rc2 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) # v0.3.0 The `v0.2` series was a _proof-of-concept_ implementation for the overall `zrok` architecture and the concept. `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. From `v0.3.0` forward, we will begin tracking notable changes in this document. # v0.2.18 * 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.
