CompHEP-4.4.91. Release notes


**ATTENTION! THE VERSION 4.4.91 IS A TEST RELEASE! STILL NOT FOR SERIOUS PHYSICS RESEARCH!**

==== Fixed bugs. ====

  * 4.4.91: Three bugs in generation of session.dat with s_comphep
  * 4.4.91: Wrong values of some commands in tag of the event default file format.
  * 4.4.91: Absence of clean-up of the program sceen if the width scheme has been changed.
  * 4.4.91: Unproper detection of libisajet in CERNLIB if there is a shared version of the libary.
  * 4.4.90: Several bugs in generation of session.dat with s_comphep
  * 4.4.90: Wrong values of some commands in tag of the event default file format.
==== Changes. ====

  * Symbolic part:
    * 4.4.90: All PDFs in the beam/strfun tables have prefix PDF (or LHA, if LHAPDF is interfaced)
    * 4.4.90: Proper generation of session.dat in s_comphep.
    * 4.4.90: Lots of internal re-arrangements (to simplify the program structure).

  * Numerical part:
    * 4.4.90: A new improved version of num_batch.pl
    * 4.4.90: Diagram viewing is available in n_comphep (a new option in the main menu)
    * 4.4.90: More convinuent behavior of the menu 'Kinematics'
    * 4.4.90: Re-arranged menu "Initial State". Beam particle and PDF are separated.
    * 4.4.90: The LHA event file format has been added, still with no extra HepML tags. 

  * Common:
    * 4.4.90: Now CompHEP is compatible with gcc-4.x
    * 4.4.90: A new version of make_tab. Now it can processes files with several subprocesses.
    * 4.4.90: CompHEP can be compiled in two different modes: with OR without LHAPDF.
    * 4.4.90: Several options in ./configure have been added: --with-gcc4, --with-lhapdf, --debug, --help 

  * Documentation
    * 4.4.91: Updated NUM_BATCH-HOWTO
    * 4.4.91: Updated LHAPDF_in_CompHEP-HOWTO
    * 4.4.91: Updated INSTALL
    * 4.4.90: New NUM_BATCH-HOWTO
    * 4.4.90: LHAPDF_in_CompHEP-HOWTO

==== Incompatibilities. ====

  * 4.4.90: A new format of the initial state in session.dat.
  * 4.4.90: ComHEP has two regimes of compilation, with or without LHAPDF. CompHEP with LHAPDF has incompatible beam    strfun tables. So, these tables will be empty if a user tries to use old files in the new version. No problems in ComHEP without LHAPDf.

==== TODO ====
  * Mixing of several event files in LHAef.
  * A new version of mk_tab compatible with the LHAEF format.
  * Check LHAPDF-compatible session.dat in internal-PDF-compatible n_comphep (and vice versa).
  * Help files for the new "Initial state" menu.
  * More convinuent behavior of the menu 'Initial state'. Initialization not by [Esc], but by a new menu command (Init).
  * Suppression of linking of all binaries against shared libraries (important for FC6/etc. installation of cernlib)
