Nebula 3.0.0-beta.3
This Linux desktop beta is the next release candidate after beta.2. Beta.2 was tagged for preparation but was not published. The source comparison contains the complete change history.
Changes since beta.2
- Harness conversations now report the provider subagent selection from their actual provider configuration, while command runtime selection remains independent.
- Harness knowledge tools now respect the active turn's access scope.
- Release preparation and draft creation verify the initiating repository admin's permission before using release credentials.
Packages and limitations
The release workflow builds Linux x86_64 AppImage and DEB packages. The DEB is intended for the prerelease APT channel after its separate promotion checks. This beta is not a stable release. Docker or Podman remains necessary for container execution and related isolated tools. Host mode runs authorized commands on the Nebula host. Physical iPhone Safari, physical macOS remote-Core, provider-diverse, and authenticated-browser workflows remain manual verification gates.
After installation, launch the desktop with nebula and run
nebula-core doctor --json.
