-v2.4 focuses on fixing real-world network testing failures observed in the field, particularly on systems running VPN software (Mullvad, Tailscale, WireGuard) and environments with virtual adapters (VMware, Hyper-V). It also resolves a latency test crash that affected every system, and fixes report encoding that caused garbled output in Notepad and legacy viewers.

+The network test was the most heavily revised area in v2.5. Specific improvements:
 
 * **Speed test** now tries three servers in sequence (Cloudflare, Hetzner HTTP, OVH) and stops at the first success, rather than failing outright if the single Hetzner HTTPS URL is blocked or intercepted
 * **SSL certificate bypass** is applied per-attempt and restored immediately after, handling VPN and proxy setups that perform TLS interception (Mullvad, corporate proxies, etc.)

 ## Troubleshooting
 
 ### Network speed test fails / SSL error
 **Cause:** VPN or proxy performing TLS inspection (Mullvad, Tailscale, corporate proxy).
-**Status:** Fixed in v2.4. The script now tries three different servers and bypasses certificate validation per-attempt.
+**Status:** Fixed in v2.5. The script now tries three different servers and bypasses certificate validation per-attempt.
 If all three fail, check firewall rules blocking outbound HTTP/HTTPS.
 
 ### Latency test always fails with "Port" error
 **Cause:** Bug in v2.21 — an undefined `$targetPort` variable caused `Test-NetConnection` to receive `Port=0`, which Windows rejects.
-**Status:** Fixed in v2.4.
+**Status:** Fixed in v2.5.
 
 ### PsPing shows "Unable to parse latency results"
 **Cause:** PsPing output formatting variation not matched by the old strict regex.
-**Status:** Fixed in v2.4. If it still shows, the debug line will display the raw PsPing output for diagnosis.
+**Status:** Fixed in v2.5. If it still shows, the debug line will display the raw PsPing output for diagnosis.
 
 ### VMware or VPN adapters flagged as "slow NIC"
 **Cause:** Old recommendation logic matched `100 Mbps` anywhere in the adapter list, including virtual adapters.
-**Status:** Fixed in v2.4. Virtual and VPN adapters are now excluded from the physical NIC speed check.
+**Status:** Fixed in v2.5. Virtual and VPN adapters are now excluded from the physical NIC speed check.
 
 ### Reports contain garbled characters (• â†')
 **Cause:** Report was written as UTF-8 but viewed in Notepad or a tool expecting ASCII/Latin-1.
-**Status:** Fixed in v2.4. Reports now use ASCII encoding and plain `*` / `->` characters.
