(no s6-svc -X anymore). Different semantics of SIGHUP and SIGQUIT
for s6-supervise.
- s6-supervise now handles SIGINT
appropriately, by forwarding it to its child's process group.
- The nosetsid file is not recognized anymore in service
directories. s6-supervise now always starts
it child as a session leader.
- Split permissions on service control are now officially supported.
New binary: s6-svperms.

managed by a user: s6-usertree-maker.
in 2.9.2.0
in 2.9.1.0
- skalibs
dependency bumped to 2.9.2.0.
- execline
dependency bumped to 2.6.0.0. (And made optional, see below.)
- The execline
dependency is now optional, and can be disabled via the --disable-execline
option to configure. Functionality that depends on execline in s6 binaries is
disabled when execline support is disabled.
- A new '?' directive has been added to s6-log,
it declares a processor command line that is spawned with the /bin/sh
interpreter.
- A new -X option has been added to s6-svscan
to better support s6-linux-init
installations.
- s6-svscan now handles SIGPWR and SIGWINCH, when
diverted, on systems that define those signals.
in 2.9.0.1
- skalibs
dependency bumped to 2.9.1.0.
- execline
dependency bumped to 2.5.3.0.
in 2.9.0.0
- skalibs
dependency bumped to 2.9.0.0.
- execline
dependency bumped to 2.5.2.0.
- All the s6-fdholder-*c binaries have been
removed.
in 2.8.0.1
- skalibs
dependency bumped to 2.8.1.0.
in 2.8.0.0
- skalibs
dependency bumped to 2.8.0.0.
- execline
dependency bumped to 2.5.1.0.
- New -d notif option to s6-log.
- New default for the -l linelimit option to s6-log:
8192 bytes.
- In the accessrules library, checking against uid/gid
now checks the uid/self key if the client and the server have the same uid, and
the gid/self key if the client and the server have the same gid.
- Everything now builds as PIC by default no matter
the toolchain's settings. Use the --disable-all-pic configure
option to build executables and static libraries as non-PIC.
- This is a major version release of s6. It is recommended to first stop
all your s6 services, then upgrade, then immediately restart your
supervision tree, then start your services again. Failure to do so
*will* cause issues if you're relying on s6-ftrigrd notifications
(which is the case, for instance, with services managed by
s6-rc).
in 2.7.2.2
in 2.7.2.1
in 2.7.2.0

in 2.7.1.0
in 2.7.0.0
- skalibs dependency bumped to 2.6.3.0.
- s6lockd and
s6-ftrigrd now use the new
textclient API and ABI from skalibs, instead of the
more generic skaclient. This is cleaner, faster code.
(s6-fdholderd still uses
skaclient, since its point is to transmit file descriptors,
which textclient does not support.)
in 2.6.2.0
- skalibs dependency bumped to 2.6.2.0.
- execline dependency bumped to 2.3.0.4.

- skalibs dependency bumped to 2.5.1.0.
- execline dependency bumped to 2.3.0.1.
- s6-ftrig-listen1 prints the last event
it received to stdout.
- The timeout-kill file is now recognized in a
service directory and allows
s6-svc -d to send a SIGKILL after a timeout if the
process is still not dead after the initial SIGTERM and SIGCONT.
in 2.5.0.0
- skalibs dependency bumped to 2.5.0.0.
- execline dependency bumped to 2.3.0.0.
- Services can now report permanent failure by having ./finish
exit 125.

s6-svlisten and
s6-svlisten1 now exit 99

configurable timeout for ./finish scripts, via the
./timeout-finish file.

s6-svlisten1 and
s6-svlisten can now wait for a 'D'
