 * The calculator GP:
 ====================
+  - Default args for user defined functions now evaluated when function is
+    called (used to be: at definition time)
+    E.g f(x) = local(z = x); z. 
+    Before: f(2) --> x
+    Now:    f(2) --> 2
+  
+  - rnfisnorm() input format has changed. Older version was complicated and
+    only worked if rnfequation(bnf, p, 1)[3] == 0  [otherwise, crash].
+    Use rnfisnorminit() now.
 
 * The library PARI:
 ===================
   - gsize() renamed to sizedigit()  [conflict with gtk]
   - hnfhavas removed (didn't work properly, hnflll provides an alternative)
+  - real zeroes are now coded on 2 words. Beware of constructs like
+    t = cgetg(lg(x), t_REAL); gaffect(y, t). If x = 0, so will be t
+  - polgalois(): old format deprecated. New preferred format for result 
+    has 3rd component giving numbering among all transitive subgroups of S_n
+    [ was ad hoc up to 7, as described above for n >= 8 ]. Old format is
+    still the default, but will eventually change. Use
+    default(new_galois_format, 1) or, in library mode, set global variable
+    new_galois_format to 1 to enable the new format.
+  - The nf structure output by nfinit has changed: 
+    *) nf.zk is now T2-LLL-reduced, not in HNF wrt the power basis
+    *) the internal components of nf[5] have changed (MC and T2 not needed
+       anymore)
+  - polred & polredabs do not take a 'prec' argument anymore [was unused]
+  - gentimer / genmsgtimer have been removed. They are superseded by TIMER
+    and msgTIMER which are fully reentrant and easier to use.
+  - (undocumented) macros buch[gen | genfu | init | iniftu]
+  - rnfisnorm() prototype has changed [ + need to call rnfisnorminit first ]
