Mihomo v1.19.27 (GitHub Release, 2026-06-06) is not a “new buttons” release. Fixes sit in the core: abnormal connections, protocol edges, rule/provider reading. For Clash Verge Rev users it’s engine maintenance.
It includes security-related fixes around QUIC, SOCKS4, Trojan, VLESS, DoQ, plus items like OpenVPN ping keepalive, PASS-RULE, and rule-provider bundle paths. Everyday users should wait for a stable client build rather than swapping cores blindly.
Not a UI-focused release
Expect fewer visible chrome changes; safety and boundaries are the point.
Security fixes worth noting
Protocol/transport hardening. Trust the upstream release notes; after upgrading, re-check connections.
New config capabilities
Use keepalive / PASS-RULE / bundle paths only if you need them in Merge.
Should Clash Verge Rev users swap cores now?
Default: wait for the client. Advanced users who already run custom cores can upgrade with a rollback plan.
Upgrade strategy
- See if the client already ships the core.
- Back up before manual swaps.
- Verify with the connections page and daily sites.
Builds: download center.
