     sessions. It only returns false now when the session data could not be
     encoded. This mainly happens with the default serialization handler
     if a key contains the pipe | character.
+  . When session.lazy_write is enabled and a session handler implements
+    SessionUpdateTimestampHandlerInterface, sessions that were read as empty
+    and remain empty at write time will now trigger updateTimestamp() instead
+    of write(). Previously, write() was always called for empty sessions
+    because session_encode() returned false, bypassing the lazy_write
+    comparison. Custom session handlers that rely on write() being called
+    with empty data (e.g. to destroy the session) should implement the same
+    logic in their updateTimestamp() method.
 
 - Standard:
   . Invalid mode values now throw in array_filter() instead of being silently

Subject: [PATCH 4/6] ext/pcntl: Fix signal table updated before php_signal4
 succeeds in pcntl_signal

Move the signal table update after the php_signal4 call, mirroring
what is already done in the SIG_DFL/SIG_IGN (integer) code path.
This prevents a stale entry in the table if sigaction fails.

Subject: [PATCH 6/6] sapi/*/Makefile.frag: install programs built with
 libtool, with libtool

When installing executables that were built using libtool, we are
supposed to use

  $ libtool --mode-install <install-command>

rather than the bare <install-command>. This is discussed ever so
briefly in the "Installing executables" section of the GNU libtool
documentation:

  https://www.gnu.org/software/libtool/manual/libtool.html

So far this has not caused a problem with GNU libtool on the platforms
that PHP supports, but there is an alternate libtool implementation
called slibtool that stores wrappers at the locations where PHP is
expecting the true executables to live. As a result, the wrappers (and
not the executables) are installed when slibtool is used to build PHP.

This is fixed by replacing,

  $(INSTALL)

with

  $(LIBTOOL) --mode=install $(INSTALL)

in the install-foo rules for the executables that are built with
libtool.

Closes GH-13674
