VERSION: release v1.5.0

[cyphar]

runc v1.5.0 -- "Why do we even have that lever?!"

This is the somewhat-delayed^Wlong-awaited first stable release of the
1.5.z release branch of runc. It contains a handful of fixes for issues
found in 1.5.0-rc.3 and an important dependency bump for libpathrs.

This is the third release of runc following our new release and support
policy (see RELEASES.md for more details). This means that, as of this
release:

 * The runc 1.2.z (and earlier) release branches are now completely
   unsupported.
 * The runc 1.3.z release branch will now only receive *high severity*
   CVE fixes, and will no longer be supported in less than 6 months (end
   of October 2026).
 * The runc 1.4.z release branch will now only recieve security and
   "significant" bugfixes.
 * Users are encouraged to plan migrating to runc 1.5.0 as soon as
   possible.
 * Despite this release being delayed by over a month, users should
   still expect a runc 1.6.0 release in late October 2026.

Added:

- "runc version" and "runc features" now provide version information
  about libpathrs when runc is built with the "libpathrs" build tag.
  (#5291, #5328)

Fixed:

- Since runc 1.3.0, the "org.opencontainers.runc.version" annotation
  included in "runc features" contained an extraneous "\n", possibly
  causing issues with tools that parse the output. It is now properly
  stripped. (#5329, #5330, #5331, #5335)

Changed:

- runc now depends on libpathrs v0.2.5 or later, and attempting to build
  with older versions will cause compilation errors. (#5291, #5328)
- Switched to go-criu v8.3.0, which reduces our binary size from ~16MB
  to ~14MB. (#5312, #5326)
