 <li> New default for the <tt>-l <em>linelimit</em></tt> option to <a href="s6-log.html">s6-log</a>:
8192 bytes. </li>
 <li> In the <a href="libs6/accessrules.html">accessrules</a> library, checking against uid/gid
now checks the <tt>uid/self</tt> key if the client and the server have the same uid, and
the <tt>gid/self</tt> key if the client and the server have the same gid. </li>
 <li> Everything now builds as PIC by default no matter
the toolchain's settings. Use the <tt>--disable-all-pic</tt> configure
option to build executables and static libraries as non-PIC. </li>
 <li> 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
<a href="//skarnet.org/software/s6-rc/">s6-rc</a>). </li>
