+- Update to new upstream release 1.5.3
+  * be compatible with MPFR version 4.0.0
+- Changes introduced with 1.5.2
+  * fix documentation of comparison functions
+  * fix bug in mpfi_sub_fr
+  * new symbols MPFI_VERSION_MAJOR, MPFI_VERSION_MINOR,
+    MPFI_VERSION_PATCHLEVEL, and MPFI_VERSION_STRING in mpfi.h
+  * detect availability of mpfr_z_sub, mpfr_z_div, and mpfr_q_sub
+    and use a custom implementation for the ones not provided by
+    MPFR (mpfr_z_sub appeared in MPFR 3.1.0, the other ones are
+    used in tests only)
+  * tadd_q does no more check overflow by default (required too
+    much memory)
+  * sign of zeros choice documented
