    convert to a sequence of multiple Unicode codepoints.

+- Opcache:
+  . The JIT config defaults changed from opcache.jit=tracing and
+    opcache.jit_buffer_size=0 to opcache.jit=disable and
+    opcache.jit_buffer_size=64M, respectively. This does not affect the default
+    behavior, the JIT is still disabled by default. However, it is now disabled
+    through the opcache.jit setting, rather than opcache.jit_buffer_size. This
+    may affect users who previously enabled JIT through opcache.jit_buffer_size
+    exclusively, without also specifying a JIT mode using opcache.jit. To enable
+    JIT, set the opcache.jit config value accordingly.
+
 - PDO_DBLIB:
  . setAttribute, DBLIB_ATTR_STRINGIFY_UNIQUEIDENTIFIER and DBLIB_ATTR_DATETIME_CONVERT
    have been changed to set value as a bool.
