Version 2

2.03

(Testing - 2026-10-29)

• Upgrade: fixes a unit that would not restart after an upgrade and needed to be switched off and on again

  • Windows Share: NTLMv2 only by default, NTLMv1 available on request through a new setting
  • SNMPv3: authentication defaults to SHA
• Exposed components (for CVE tracking): Linux 6.18.59, OpenSSL 3.5.9, Go 1.27.3, OpenSSH 9.9p2, Samba 4.22.11, Net-SNMP 5.9.3.
