ClouDNS vs runc: at a glance
What is ClouDNS?
ClouDNS widens its SSL catalog and adds maintenance windows to monitoring
ClouDNS keeps adding direct registry accreditations, with .LOVE, .BAR, .CLICK, .TO, .DIY, .FOOD and others since mid-September. Alongside them it is building out the services around domains: Maintenance Mode for monitoring checks, new Status Page alert options, and now RapidSSL and Actalis certificates, including wildcard options.
What is runc?
runc 1.6.0-rc.1 lifts the 1024-CPU limit and refuses settings it used to quietly ignore
The 1.6.0 cycle opened on October 6 with a first release candidate that is mostly cleanup: deprecated libcontainer APIs removed, Go 1.26 now required, urfave/cli moved from v1 to v3, and the binary about 15% smaller on amd64. The changes with operational weight are that cpuAffinity and NUMA memoryPolicy no longer stop at 1024 CPUs or nodes, and that a container asking for a read-only rootfs without its own mount namespace is now refused. Eleven days earlier 1.5.2 worked around a kernel bug, present since v6.17, that corrupted memory inside runc and caused random crashes on cgroup v2. It also stopped runc exec --cgroup from escaping into a sibling cgroup.

ClouDNS
5.0INFRA · APIS
ClouDNS widens its SSL catalog and adds maintenance windows to monitoring
◆ Current state
ClouDNS keeps adding direct registry accreditations, with .LOVE, .BAR, .CLICK, .TO, .DIY, .FOOD and others since mid-September. Alongside them it is building out the services around domains: Maintenance Mode for monitoring checks, new Status Page alert options, and now RapidSSL and Actalis certificates, including wildcard options.
◆ Where it's heading
The registrar expansion continues at roughly one batch of TLDs a month, while monitoring and SSL become fuller products in their own right. The direction is a one-stop domain, DNS, certificate and uptime provider.
◆ Prediction
Another batch of TLD accreditations is the likeliest next entry; further monitoring features look likely given two releases since September.

runc 1.6.0-rc.1 lifts the 1024-CPU limit and refuses settings it used to quietly ignore
◆ Current state
The 1.6.0 cycle opened on October 6 with a first release candidate that is mostly cleanup: deprecated libcontainer APIs removed, Go 1.26 now required, urfave/cli moved from v1 to v3, and the binary about 15% smaller on amd64.

Eleven days earlier 1.5.2 worked around a kernel bug, present since v6.17, that corrupted memory inside runc and caused random crashes on cgroup v2. It also stopped runc exec --cgroup from escaping into a sibling cgroup.
◆ Where it's heading
The project keeps converting silent behaviour into explicit behaviour. Read-only requests that were ignored now fail, a umask that was dropped is now honoured, and poststart hooks moved to conform to the runtime spec. The same maintainers are shrinking the surface underneath, dropping the deprecated API and the high-level cilium/ebpf path, which took roughly 7.5% off the 1.5.2 binary. Stricter behaviour plus a smaller dependency set is what a component under every container host would be expected to do between majors.
◆ Prediction
1.5.0's notes pointed to a 1.6.0 in late October 2026, and the feed so far shows only rc.1, so further release candidates or the final are the next entries to expect. The refused read-only configurations are the change most likely to surface as user reports during testing.
