Erlang/OTP                                               October 6, 2004


LAST MINUTE INFORMATION -- Release of Erlang 5.4/OTP R10B


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 R9B and R9C compiler but
        doing so may give you some performance improvements.
	
1.6     This release, as the R9C release, contains several unsupported features
	for tryout. Most notably the sun-sparc-solaris 32 bit version contains
	support for HiPE native code compiling and loading. All platforms
	except Windows also contain an emulator using a shared (global)
	heap. Running 'erl -shared' starts this emulator. Note that no support
	is given for HiPE or the shared heap emulator; they are delivered for
	testing purposes and should not be used in a production
	environment. Information about HiPE can be found at this site:
	http://www.csd.uu.se/projects/hipe/


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

2.1	For the Sparc Solaris environment, Solaris8 (2.8) and above is 
	supported. The emulator no longer runs on older Solaris versions.
	Also an Ultrasparc (sun4u architecture) is required.

2.2	There are two sun-sparc-solaris versions, one for 32bit
	environment and one built for a 64bit environment. If one hasn't 
	special need for the 64bit address space, the 32bit version is
	in all senses to be preferred. The 64bit version consumes
	roughly twice the amount of memory and is not performing as well 
	as the 32bit version in terms of speed. 

2.3	HiPE native code loading is enabled by default, but compiling to 
	native code is not supported in the sense that our support department
	can give no help on subjects due to native code compiling. 

2.4	The Solaris8 32bit and 64bit versions are built using the following 
	compilers:
	GCC 3.1.1
	Sun JDK 1.2.2_05
	

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 8.2 x86		
	Redhat 9

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.
