Changes v.4.2.1 -> v.4.4.0
============================


Content

1. Incompatibilities
2. Fixed bugs and clean up code.
3. Documentation and help files
4. Interface
5. Source structure
6. Miscellaneous


1. Incompatibilities
----------------------

New scheme of work with initial beams and final composite particles was 
changed.

If you have a private model and want to use them with CompHEP-4.4.0, you 
have to copy cpart1.mdl file to cpartN.mdl file where N is a number of 
your model by commands:

   cd path_to_user_working_directory/model
   cp cpart1.mdl cpartN.mdl

All new composite particles must be introduce into table by using edit model 
facilities.


2. Fix the bugs and clean up code.
-----------------------------------

2.1. Compilation bug when CERN libraries do not available
2.2. Make randomization of momenta of 2 last particles in event file.
2.3. QCD lambda are taken from PDF now.


3. Documentation and help files
--------------------------------

3.1. SYMB_BATCH-HOWTO
3.2. NUM_BATCH-HOWTO
3.3. Help for beam table (s_beam_1.txt)
3.4. Help for structure function table (s_strfn_1.txt)


4. Interface
-------------

Symbolic part
	Add table for initial beam (proton, anti-proton, ...)
	Introduce switch F3 from beams to particles and vs.
	Change composite particle table (see [1])
	Introduce switch F3 from composite particles to particles and vs.
	Symbolic conservation law is off by default.
	LOCK file is restored.
	Maximum sum of output and input particles (MAXINOUT) is 10 by default.

Numerical part
	re-arrange menu "Width scheme"
	Change "Equiv.Photon(...)" to WWA

Common
	Re-arrangement of usage of messages and warnings.



5. Source structure
--------------------

5.1. All CompHEP libraries were collected into lib subdirectory
5.2. CompHEP PDF file standard description move to tbl-pdf directory
5.3. Files drandXX.[ch] move to service2 subdirectory



6. Miscellaneous
----------------
