- Options: VersionCommand, VersionTimeoutSeconds, MinimumVersion, EnforceMinimumVersion
- Version probe service and parser; startup enforcement when EnforceMinimumVersion
- Save flow: block save on probe failure (VersionProbeFailed) or version below minimum (UnsupportedVersion)
- Status API and Dnsmasq page: show version with tooltip, link to CHANGELOG
- Readiness: GET /healthz/ready (version + dnsmasq running when StatusCommand set)
- MapReadyHealthCheck extension; Dockerfile HEALTHCHECK + curl; compose healthcheck and service_healthy
- Docs: README and agents.md updated
- Fix do-0x20-encode: clearing pending when toggling back to original (Disabled/Default)
- Do0x20EncodeDisplay: uncheck uses pending.OldValue when present
- EffectiveConfigFieldDisplay: use pending.OldValue as _valueAtActivation when re-entering with pending
- Effective config: validation errors/warnings in toolbar and save modal, revert from modal
- Custom displays: Do0x20EncodeDisplay (tri-state), KeyOnlyOrValueDisplay
- ExplicitToggleState, config/apply support for do-0x20-encode, option help and tests
- Process: Add IProcessHandle, ProcessOutputLine, StartAsync; RunAsync via StartAsync+WaitForExitAsync. Wait for stdout/stderr stream close before reading to fix empty restart output. ProcessTimeouts; ReloadService/StatusController/LogsService use config timeouts.
- Effective config: Rename reload→restart in save/restore result types and UI. Save modal: show restart output, danger alert, Stop editing/Continue editing (yellow), footer one-line; fallback exit code when no output; ensure pre visibility (CSS). Restore failed: combined output helper.
- Status script: When dnsmasq dead, run dnsmasq --test and show config error in status block (Docker harness; DNSMASQ_CONF).
- listen-address: Allow IPv6 (ValidateDraftValue accepts InterNetworkV6).
- Docker test: RestartCommand uses DnsmasqOptions timeout; DnsmasqOptions RestartTimeoutSeconds.
- Register ISettingsModalService, INotificationService, IUpdateCheckService via assembly scanning (marker interfaces)
- Add IApplicationOptionsValidator<TOptions> marker; scan only those for IValidateOptions registration
- Fix ApplicationLifecycleLoggingHostedService: log RestartCommand/ReloadCommand/StatusCommand (no ApplyCommand)
- NavMenu: spin animation for update-check button icon when checking; single icon with conditional nav-footer-spin class
- Add NotificationHost/NotificationToast components and NotificationService for toasts
- Effective config save flow, restore result, save service; various EffectiveConfig and DnsmasqOptions/validator updates
- Test and script updates; docker-compose.test.yml, appsettings, DnsmasqConfKeys/tooltips/sections
- Managed hosts file (zz-dnsmasq-webui.hosts): app reads/writes only this;
addn-hosts in managed config loads it. SystemHostsPath is read-only display.
- Hosts page: editable managed file; then 'Other hosts (read-only)' (system
hosts when configured and !no-hosts, plus addn-hosts excluding managed).
- GET api/hosts/readonly for read-only files; no-hosts hides system hosts.
- HostsFileSection.razor component; fix space before read-only badge.
- Test harness: show container /etc/hosts (default SystemHostsPath).
- Config parsing/sources, tests and client updates for new hosts model.
- Static hosts: read dhcp-host from all config files; show external as read-only
with Source column; IsEditable + SourcePath on DhcpHostEntry; reject save if
managed entry duplicates MAC from another file (400 + message)
- Lease field: single input + datalist (type or select), remove Other dropdown
- MAC field: single input + datalist from current leases, TryFillFromLeaseByMac
- Add host: default Name=*, suggest next free IP from DHCP range
- Leases: configurable refresh polling; Settings modal for interval (client-side)
- DhcpHostsClient: surface 400 error body message on save failure
- App title config (ApplicationOptions), nav/layout/error/hosts tweaks
