FreeCORE 15.0-U2.1

The 15.1 web interface, Python 3.12 and iocage 1.13 on the maintained 15.0 line, with the plugin store and plugin jails kept, and the security updates and fixes of the 15.1 line that apply to 15.0.

FreeCORE 15.0-U2.1 continues the maintained 15.0 line, which carries the TrueNAS CORE 13.3 storage, jail, plugin and VM model forward. It is a maintenance update for 15.0-U2.0. It moves 15.0 onto the web interface, Python and iocage that 15.1 uses, keeps the plugin store and plugin jails, and carries the security updates and fixes of the 15.1 line that apply to 15.0.

Release date: 6 October 2026

Changed

• The web interface moves to the 15.1 codebase (Angular 22). The plugin store and the 15.0 virtual machine pages stay; pages that only 15.1 has, such as Applications, are not part of 15.0. A Swedish translation is offered.
• The system Python moves from 3.11 to 3.12, as on 15.1. A script that calls python3.11 by path needs to call python3 instead.
• Jails and plugins run on iocage 1.13, the base 15.1 uses. The plugin store and plugin jails stay.
• System > ACME DNS offers Cloudflare, DigitalOcean, OVHcloud and Shell alongside Amazon Route 53, as on 15.1.
• Leaving an Active Directory domain uses the system's Kerberos credential cache, as TrueNAS SCALE does, and removes the computer account from the domain.
• The iXsystems NVDIMM driver (ixnvdimm) and the M-series NVDIMM alerts that used it are removed. FreeBSD's nvdimm(4) driver stays.

Security

• Security and maintenance updates to bundled software: Samba 4.24.7, Apache 2.4.69, OpenLDAP 2.6.15, the root certificate bundle (NSS 3.130), jq 1.8.2 and Beautiful Soup 4.15.0.
• A process with many shared libraries no longer risks corrupting its own memory the first time it starts another program: the runtime linker takes upstream FreeBSD's fix for this (PR 295991) in place of FreeCORE's larger spawn stack.

Fixed

• SMB: the share list can be browsed again while any user is marked as a Microsoft Account.
• SMB: changing a user's Microsoft Account setting takes effect without restarting SMB.
• Certificates: deleting a certificate issued through ACME works again; it stopped with an internal error when the certificate was revoked.
• The return point captured by an in-place move from TrueNAS CORE names the boot environment the system came from even when the system clock was wrong at installation.
