Unity Hub 3.18.0

This release introduces a new standalone CLI for Unity Hub. Unlike the existing CLI, which runs through the Hub application, the standalone CLI is distributed as a separate binary and can be installed, updated, and used independently of Unity Hub. View documentation for the CLI here.

The existing CLI remains supported in this release.

Key updates for the standalone CLI include:

Improved CLI performance and responsiveness, with simple commands running up to 10x faster.

Reduced CLI startup time to under 100 ms, compared to roughly 5 seconds previously.

Added support for updating the standalone CLI independently with unity upgrade.

Feature parity is maintained with the existing CLI with future updates bringing new features and enhancements

The standalone CLI supports all platforms supported by the Unity Editor.

Custom Templates are now officially supported, providing a standardized way to create and share project templates directly in Unity Hub.

New custom templates can be created from an existing project by selecting Save project as custom template from the project menu or from the New template button on the new Templates page.

Template creation supports defining a name, description, version, thumbnail image, and signing organization.

Template signing and verification are supported to improve trust and consistency when sharing templates across teams.

Custom templates can optionally be linked to GitHub, GitLab, or Unity Version Control (UVCS) repositories.

A new Templates page displays all templates in the selected template directory, and templates can be searched for by name or filtered by Editor.

Existing templates can be added to Unity Hub by moving them into the selected template directory, or by updating the directory in Settings > Templates to point to the local template location.

Added a Size column to the Projects table that displays the disk size of each Unity project, excluding generated directories such as Library, Temp, and build artifacts.

Updated the layout of the New Project page and replaced template category tabs with a filter dropdown.

Fixed an issue where long values in expanded row content could cause the Projects table to scroll horizontally.

Updated the downloads badge in the top bar to prioritize active downloads over failed downloads.

Fixed an issue where paused downloads could sometimes fail to resume.

Improved proxy support across the Hub to ensure network requests consistently respect proxy configuration, including environment variables, system proxy settings, PAC files, WPAD, custom CA certificates, and fallback to direct connections when a proxy is unavailable. This also fixes issues where some downloads and services could bypass the configured proxy or fail TLS validation, and improves proxy credential handling for additional credential formats.

Added a new macOS-only setting under Settings > Appearance > Menu bar that lets you hide the Unity Hub icon from the macOS menu bar without restarting the app.

• macOS

Improved the reliability of elevated install and setup flows on Windows, including better handling for subprocess output, cancellation, and cleanup.

• Windows

Added security hardening improvements across the Hub, including protections against supply chain risks and OAuth-related enhancements.

Continued reducing third-party dependencies used by the Hub.
