Previous versions: 3.2, 3.1, 2.19, 2.18, 2.17.1, 2.17, 2.17beta, 2.16.2, 2.16, 2.15, 2.14.1, 2.14, 2.13, 2.12.2, 2.12.1, 2.12

1. Bug fixed in reading levels file when preparing collective levels for ECIS (R. Capote).
2. Bug fixed in reading Coulomb parameters of o.m.p. from the RIPL-2 file (affects charged particle channels)(R. Capote).
3. Relativistic correction in tl.f removed (gamma=1). It is not needed since SCAT2 and ECIS take care of it (R. Capote).
4. Bug in EMPEND, which caused skipping the last but one energy point fixed (A. Trkov).
5. EMPEND formats branching ratios in the ENDF file (A. Trkov).
6. xterm closes when calculations are done as it was in download.html 2.17 and earlier (p.3.iii below removed) since it was inconvenient for running piece-wise and multiple calculations(M. Herman).
7. gamma-strength function uses a temperature consistent with the current level densities for the final state (not for the initial one as erroneously coded before) (M. Herman).
8. Beta version of the new GUI (Xrun.tcl) added (M. Herman).
9. Corrected renormalization of the absorption cross section in DEGAS (E. Betak).
10. Corrected way of restricting exciton configurations used in DEGAS (E. Betak).
11. Maximum number of excitons used in DEGAS set to 5 (3 configurations) (M. Herman).
12. PLOTC4 updated by A. Trkov to produce gamma-spectra (continuum contribution from the capture reaction has not yet been included).
13. Bugs in PLOTC4 fixed by A. Trkov. PLOTC4 tested on Linux with g77 and Absoft90 ver. 7.0 compilers and on Ms Windows with Lahey 75.
14. If discrete levels are inconsistent with Gilbert-Cameron level densities and LEVFIT is non-negative calculations are continued using nuclear temperature taken from the systematics. Appropriate massage is printed and cumulative plot displayed (without blocking further calculations) (M. Herman).
15. Bug in empire-specific level densities at very high energies (close to 200 MeV) when level density exceeds capacity of the 32-bit word has been fixed by ignoring fit to the discrete levels (unfortunately in all nuclei) (M. Herman).
16. File Ko in tl.f is rewound to avoid messages that particular omp is not found in the local file (M. Herman).
17. Number of iterations when fitting discrete levels with Gilbert-Cameron level densities limited to 300 to avoid the possibility of infinite loop (M. Herman).
18. Z=105 name changed to 'Db'; thanks to Erik Strub for pointing it out (M. Herman).
19. Problem with the discontinuity of neutron capture cross section when incident energy becomes lower than the integration bin width has been solved. Capture cross sections, even at very low energies (<10 keV) can now be calculated even with as few as 50 energy bins (M. Herman).
20. All collective levels are used in ECIS calculations with DIRECT=1,2, even if they can not be excited because of the too low incident energy. In the previous download.html only open channels were considered and coupling to the closed ones was ignored (R. Capote).
21. Minor corrections of nuclear masses in EMPEND avoid potentially infinite loop while the ENDF formatted file is processed by SIXTAB (A. Trkov).
22. Thresholds for particle emission channels corrected in EMPEND (A. Trkov).
23. Discrete level library updated to the RIPL-2 version of September 24, 2002).

2. Bug in reading RIPL-2 discrete levels fixed by R. Capote.
3. All scripts modified: (i) all links made symbolic to allow for using network drives, (ii) ./ added in front of calls (thus ./ is no longer needed in the PATH), (iii) xterm remains open after calculations are completed so that runtime messages can be inspected (M. Herman).
4. GUI background color changed to gray (M. Herman).
5. guizvv.tcl for graphical comparison of up to three calculations/evaluations (already present in 2.17) modified (nonstandard Tcl/Tk widget replaced) (M. Herman).

1. Bug in adding CN contribution to angular distributions for discrete levels corrected. Gammas were added to CSAlev(.,.,0) in HF-comp.f with 0 being out of dimension. Adding of gammas is now blocked. Thanks to V. Plujko for pointing it out.
2. PLOTC4 updated by A. Trkov to produce spectra (including double-differential ones) for outgoing protons and alphas. Structure of the Post Script files improved.

4. Optical model database again updated to the preliminary version form RIPL-2
5. EXFOR database updated to the version of 18.05.2001 (NOTE: previous EXFOR database will NOT work due to a different directory structure).
6. File with levels (14) closed at the end.
7. The new 'setup-emp' script assists installation procedure and allows to use EXFOR library and/or HF-BCS level densities directly from the CD-ROM without copying them onto the hard disk.

6. GUI starts with gvim editor selected by default (M. Herman)
7. Two compilation warnings in tl.f fixed (M. Herman)
8. Cumulative plots of discrete levels created as a Post Script file rather than being dumped onto the screen. Stored as *-cum.ps and available through GUI (M. Herman)

10. List of warnings available through GUI (M. Herman)
11. Tabulated HFBCS levels densities as provided to RIPL-2 by S. Goriely included as additional level density option (M. Herman)

1. General clean-up of the FORTRAN source
2. New organization of modules that reflects physical contents
3. Check whether MSD cross section is not larger than the fusion cross section
4. Gamma cascade in the first CN is default if CN excitation energy is below 20 MeV and can be controlled with GCASC in optional input
5. l=0 transfer strength in MSD-orion set to the self-consistent value by default (rather than to GMR energy as before)
6. Fusion cross sections read from the file name.fus are treated as fusion cross sections at subsequent l values (starting with l=0) rather than fusion cross sections to a given spin of CN. Transmission coefficients are calculated from the read values and a proper angular momentum and parity coupling is performed to obtain Compound Nucleus spin distribution.
7. Error in BCS blocking in TRISTAN removed
8. BCS blocking in TRISTAN made automatic (no input required)
9. pipe.c replaced with the one by R. Capote
10. Automatic retrieval of EXFOR data
11. Link to EMPEND to create ENDF formatted file
12. Link to X4TOC4 and PLOTC4 to produce plots at the end of the run
13. Fission barriers for Z>102 according to Myers & Swiatecki Phys. Rev. C60 1999
14. FITLEV creates a whole set of cumulative plots without interaction
15. Fusion barrier can be read from input (BFUS)
16. Bass option for fusion disabled
17. Distributed fusion barrier model now relies on the CCFUS fusion barrier
18. OMPAR (.omp) file with optical model parameters produced and used for input

1. Energy shift used to fit low energy discrete levels gradually decreased between Ecut and neutron binding to recover agreement with Dobs.
2. Entire code checked with FTNCHEK and some errors corrected (undefined variables, unreferenced ones removed).
3. All DO loops given separate endings (END DO, no labels)
4. Entire code consistently indented.

1. source directory added with explicit double precision source (no compiler -r8 option required).
2. roign.f routine replaced by roemp.f. It fits dynamical level densities (BCS approach below critical energy) to discrete levels by applying an energy shift. ATTENTION: for the time being these shifts destroy agreement with Dobs at neutron binding.

1. Error in the determination of pairing corrections in readnix.f (in the case of Gilbert-Cameron) removed.
2. Errors in coding of the dynamical level densities removed.
3. New, EMPIRE specific, systematics of level density parameter 'a' for dynamical level densities introduced and set as default if dynamical level density chosen. This systematics fits Ilijnov-Mebel D-observed using EMPIRE formulas for l.d. If an experimental value for a given nucleus is present in the ldp.dat file it is taken. Average normalization factor is calculated for these cases and applied for the remaining ones for which there is no experimental value. All nuclei are treated as deformed as far as the collective enhancement is concerned. Temporarily damping of the collective effects has been removed, i.e. level densities are calculated in the adiabatic approach.
