FreeCORE 15.0-U1.5

SMB noacl, terminal rendering, VM console and boot fixes, and the return of arcstat on the maintained 15.0 line.

FreeCORE 15.0-U1.5 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-U1.4 with virtual machine, SMB, web terminal and service fixes.

Release date: 15 September 2026

Added

• WireGuard peers report their last handshake and per-peer transfer counters. This was listed under 15.0-U1.4 in error; it ships in this release.
• arcstat and arc_summary are back in the base system, as on TrueNAS CORE 13.3.

Fixed

• SMB shares whose VFS objects include noacl accept client connections again. The noacl module no longer fails to load.
• The web interface's Shell and jail consoles no longer clip the bottom of each line, so underscores and descenders are visible, and the terminal opens once its font has loaded.
• UEFI virtual machines boot to the display again instead of the serial console, and VIRTIO virtual machines with more than one disk start again. See VM Firmware.
• The VM web console works when VNC is bound to all addresses, and bhyve no longer forces a VM exit on every guest PAUSE instruction.
• rar2fs starts after the pools are imported, so its mounts survive a reboot.
• iocage basejail upgrades across major releases work again.
• The API documentation is served from the system itself and describes API-key authentication.
• The kernel reports the FreeCORE 15.0 build it was made from (uname -v), and the source manifest the image was built from is readable at /etc/repo-manifest.
• The Memory dashboard card states its ECC status as text.
• ACME certificate issuance works with an ACME server that returns no account contact, as Let's Encrypt now does; a registration stranded by that failure is repaired in place, and the certificate request is handed to the order in the form the ACME client requires. This shipped in 15.0-U1.4 and was not listed there. See Requesting ACME Certificates.
