LAST MINUTE INFORMATION -- Release of Erlang 5.5/OTP R11B


1.      GENERAL
        -------

1.1     Installation Guide

        The installation guide can be found in

                <inst-root>/doc/installation_guide/part_frame.html

1.2     Java

        The Java sources for Solaris were compiled using JDK 1.2.2;
	for the other platforms using JDK 1.4.2.

1.3     Disk space

        An installation of Erlang/OTP needs approximately 115 MB of
        disk space.

1.4     The package contains HTML documentation. You can also get this
        documentation preformatted for printing in PDF format from

            http://www.erlang.se/doc/

        This site also contains HTML documentation for older releases
        as a reference.

1.5     You don't need to recompile your Erlang object files (BEAM
        files) that were compiled with the R10B compiler but
        doing so may give you some performance improvements.

1.6	New in the R11B release is the SMP emulator, that can be started
	with 'erl -smp' (on Unix platoforms, not on Windows). See the
	release notes for the Erts application more further details.	


2.      NOTES ABOUT THE SOLARIS VERSION
        -------------------------------

2.1	For the Sparc Solaris environment, Solaris8 (2.8) and above is 
	supported. The emulator doesn't run on older Solaris versions.
	Also an Ultrasparc (sun4u architecture) is required.


3.      NOTES ABOUT THE VXWORKS VERSION
        -------------------------------

3.1	The platform VxWorks is discontinued in the sense that only the 
	libraries (erl_interface and ic's libraries) are supported. Running
	the erlang emulator on VxWorks is still possible but it's no longer
	maintained. The VxWorks release is still packaged as a full release
	and the emulator runs, but no support will be available for anything
	but the communication libraries. 

4       NOTES ABOUT THE LINUX VERSIONS
        -----------------------------

4.1     The following linux distributions/version combinations are supported 
	and tested:
	
	Suse 9.2 x86		
	Montavista/PPC

5.      APPLICATIONS NOTES
        ------------------

5.1     For the SSL and crypto applications to work, you need to have 
	OpenSSL 0.9.7 or higher installed on the system. The usual 
	installation directories are searched for a working OpenSSL library.
