What is runc?

runc now publishes an end-of-life calendar, and three branches shipped the same CVE fix in two days.

1.5.0 in June was the first stable release of the 1.5.z series and the third under runc's formal release and support policy: 1.2.z and earlier are unsupported, 1.3.z receives only high-severity CVE fixes until the end of October 2026, and 1.4.z is limited to security and significant bugfixes. A month later 1.5.1 fixed a real-world regression — the maskPaths optimisation from 1.5.0-rc.3 broke tmpfs mounts with nr_inodes=1 on Ubuntu 20.04 kernels. In mid-June, CVE-2026-41579 was fixed simultaneously across 1.3.6, 1.4.3 and 1.5.0-rc.3 and released with no embargo.

What is Jackett?

Jackett in pure tracker-maintenance mode, daily domain and category updates only

Jackett ships automated daily builds that consist almost entirely of tracker-library upkeep: domain alternatives, broken selectors, new categories for individual sites. The core indexer-proxy architecture is stable and unchanged. The only user-visible improvement in this window is hiding the API key on the dashboard.

runc now publishes an end-of-life calendar, and three branches shipped the same CVE fix in two days.

◆ Current state

1.5.0 in June was the first stable release of the 1.5.z series and the third under runc's formal release and support policy: 1.2.z and earlier are unsupported, 1.3.z receives only high-severity CVE fixes until the end of October 2026, and 1.4.z is limited to security and significant bugfixes. A month later 1.5.1 fixed a real-world regression — the maskPaths optimisation from 1.5.0-rc.3 broke tmpfs mounts with nr_inodes=1 on Ubuntu 20.04 kernels. In mid-June, CVE-2026-41579 was fixed simultaneously across 1.3.6, 1.4.3 and 1.5.0-rc.3 and released with no embargo.

◆ Where it's heading

The project is behaving like infrastructure with a contract. Publishing dated support windows and shipping a coordinated fix across every live branch on the same day is the operating posture of a component that sits under every container on a host, where operators need to know what they are still entitled to. The CVE itself is instructive: a /dev symlink escape in the same family as three earlier CVEs, found by re-auditing the rootfs preparation code that had been hardened before.

◆ Prediction

1.5.0's notes state that a 1.6.0 is expected in late October 2026, which is also when 1.3.z support ends — so the next milestone is that pairing. Expect 1.5.z patches until then.

5.0

Jackett in pure tracker-maintenance mode, daily domain and category updates only

◆ Current state

Jackett ships automated daily builds that consist almost entirely of tracker-library upkeep: domain alternatives, broken selectors, new categories for individual sites. The core indexer-proxy architecture is stable and unchanged. The only user-visible improvement in this window is hiding the API key on the dashboard.

◆ Where it's heading

The last 10 entries show no feature development — every commit is tracker registration data. Jackett's trajectory is entirely reactive to the torrent ecosystem: trackers move domains, change engines, and die; Jackett follows. There is no observable product initiative in this window.

◆ Prediction

The entries don't support a confident prediction about new feature direction. Daily tracker maintenance will continue as the primary output; any substantive change would come from outside this pattern.
