dhcpcd-8.1.2 has been released with the following changes:

• hooks: STOPPED is now run on timeout and exit
• musl: Fix build
• Linux: Validate RTM_NEWADDR/RTM_DELADDR messages
• BSD: Use IP_REVCIF rather than IN_PKTINFO
• build: address sanitisation is enabled for debug builds
• build: Improve detection of dlsym requirements
• DHCP: When rebinding, ensure we have a DHCP ARP state
• RA: Sort routers when reachability changes
• RA: Apply hoplimit, reachable and retrans timer values to kernel
• RA: Warn if advertised MTU > interface MTU
• OpenBSD: Fix carrier detection for OpenBSD-6.6
• dhcpcd: Report SSID connection to when we gain carrier
• DHCP: Fix corruption of address flags when renewing

The last issue was the cause of the recent report about dhcpcd pegging a CPU, so this is quite an important upgrade from 8.1.1
