[Joël BERTRAND]

	Hello,

	New RPL/2 release is available with som bugfixes (in tools and in RPL/2 
itself) :

- sqlite is upgraded;
- OpenSSL is upgraded;
- lapack is upgraded to 3.5.0;
- use of uninitialized variables is avoided in FORALL;
- giac is upgraded;
- units is upgraded;
- gnuplot is upgraded;
- major bug is fixed in both FOR and FORALL (segmentation fault if both
instructions are not followed by a name).

	Enjoy,

	JKB
