## 0.2.0 (2026-09-29)

### New
- High availability: standby servers with a witness for automatic failover, a shared address or separate networks, automatic rejoin and rolling updates. One licence covers the cluster: each server gets its own seat when it first becomes active.
- Other sites: connect another site on Linux or Windows with one command.
- Custom sensors: REST API values and scripts over SSH or PowerShell, compatible with Nagios plugins.
- Database checks for SQL Server, MySQL and PostgreSQL, and Hyper-V host and virtual machine checks.
- Vendor templates for Dell, HPE, Synology, QNAP, APC and other UPSs, printers and FortiGate.
- Business services that group checks into one service with its own status, availability and alerts.
- NOC wall screen, wall-screen links for TVs and public status pages.
- Mail server checks (SMTP, IMAP, POP3), ping jitter, Microsoft 365 service health, and Azure and AWS monitoring.
- Sign in with Microsoft, two-step sign-in with an authenticator app, and API keys with an API reference.
- Email alerts to several people through Microsoft 365, Google or your own mail server, with Send test.
- SSL certificates: upload a wildcard or single-name certificate, or use one your proxy (such as pfSense) provides.
- Send feedback from the console; a failed checks page; cancel a running scan.
- Discovery: one-click site scans that identify devices, a daily rescan and a list of new devices to approve.
- Device categories, and logins assigned per device.
- Licensing with a 30-day trial, activated from Settings, and updates from the TarleyNode Update Center that install only when an administrator chooses.
- Getting started: a how-to for every feature.
- Licence terms: accepted at first setup and linked from licence activation and About TarleyNode, with the privacy notice, refunds and support pages.
- Open-source licences: every bundled component and its licence, in the console and as THIRD_PARTY_NOTICES.txt in each release.

### Fixed
- Syslog and trap alerts no longer close as soon as their site reports in.
- A scan waiting for a site that was replaced no longer leaves it stuck on scanning.
- Editing a mail, Microsoft 365 or cloud check keeps all of its settings.
