v2.5.16 – v2.5.23 — 2026-07-04

• fix(backup): remove unused net import (agent build of v2.5.15 was broken)
• fix(backup): real FTPS connection test + rclone as a dependency (install+update)
• fix(release): preflight build guard — no more release on build failure
• feat(backup): FTP AND FTPS selectable + cert-check toggle for self-signed
• fix(backup): FTP connection test creates the target folder (rclone mkdir instead of lsd)
• fix(backup): FTP schedule inherits global settings (no double entry) + TLS mode is saved
• feat(backup): custom backup storage only with package permission (perm_custom_backup_target)
• fix(backup): 500 when switching to weekly (month_day=0 violated a constraint)
• fix(dns): quote TXT/SPF template records — otherwise a 422 kills the whole zone batch
• fix(ip/dns/ssl): webspace IP change is honored by the SSL preflight + DNS template
