What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

- **security** — Agents now verify HTTPS certificates; configure CA_CERT_FILE if connecting to a hub with self-signed or untrusted certificates
- **added** — Add ZFS pool and dataset monitoring
- **added** — Add container health alerts with log excerpts in notifications
- **added** — Add alerts for failed systemd services
- **added** — Add alerts for CPU I/O wait and steal time
- **added** — Add cumulative disk read and write totals to the Disk I/O sheet
- **added** — Add Greek and Uzbek translations
- **added** — Add custom root disk names and sort disks alphabetically
- **changed** — Improve alert security by enforcing system ownership and blocking additional internal notification URL ranges
- **changed** — Improve ATA SMART warnings for critical attributes
- **fixed** — Fix a hub crash caused by concurrent SSH client shutdown
- **fixed** — Fix host CPU and memory totals when Docker runs in a VM on macOS or Windows
- **fixed** — Fix multi-line TOKEN_FILE loading
- **fixed** — Fix QNAP MD RAID arrays being incorrectly reported as failed
- **fixed** — Fix Intel GPU power data disappearing between samples
- **fixed** — Fix swap usage calculations to include cached swap
- **fixed** — Fix agent payload failures caused by invalid UTF-8 in battery names
- **fixed** — Fix uptime reporting inside Linux containers
- **fixed** — Fix fan discovery on legacy hwmon devices
- **fixed** — Fix CPU model detection on MIPS systems

:warning:  **Potential breaking change:** Agents now verify HTTPS certificates. If an agent connects to a hub using a self-signed or otherwise untrusted certificate, configure `CA_CERT_FILE` with the appropriate CA certificate or the connection will be rejected.
