Version 1.56 (current version)
------------------------------
Two significant bugs are fixed.

1 Tubular and box-shaped cross-sections causes the application 
  to fail during loading. Fixed!
2 Sometimes the application hanged while editing the load case
  factors in the Action/Load Case Manager window. Fixed!

Version 1.55
------------

Version 1.55 hos not have dramatic changes. It is mostly a sub 
version upgrade, which has been cleaned of known bugs and where 
we presented a few improvements:

1 Element and nodal load can be deleted using standard 
  approach – select and delete. You do not need to open 
  the load property window in order to delete the load, anymore.
2 We prepared a registration wizard that helps you to register 
  in a secure way. The wizard collects required registration 
  information, formats  and encrypts it to make the information 
  transmition secure.
3 A special document message system was developed and put into 
  service. The document message system (DMS) will be used to 
  deliver you relevant information directly into the AMSES Frame2D. 
  No user intervention is required to get the information. Do not 
  worry, we will use the system sparingly.
4 Tubular and box shaped cross-sections (along with circle, 
  rectangle, T-shape, I-shape) can be specified using their 
  natural coordinates.
5 Significant number of bugs and shortcomings were removed. 
  This makes the application even more stable.


Version 1.50
------------
1 Element on elastic ground: 
  The linear finite element may be put on the elastic ground 
  (Winkler halfspace). The elastic ground is modeled as a continuos 
  linear spring. This option allows you to easily solve a brand new 
  family of foundation problems. 
2 New kinematically exact non-linear finite element: 
  This new state of the art finite element has replaced the old second order 
  theory element. New element is very precise and 'kinematically exact'. 
  This means it may be used to solve large displacements, large strains problems.
3 New skewness load case type: 
  The skewness load case knows how to set structural initial imperfections. 
  Several imperfections in different directions may be specified.  
  This load case replaces tedious calculation of equivalent imperfection forces. 
4 New creep load case: 
  This load case enable you to simulate concrete creep effects for all 
  concrete structures. It uses special two step approach, which is based 
  on reduced modulus of elasticity. 
5 Envelopes: 
  Envelopes are used to extract maximums and minimums of selected load cases. 
  The extraction is based on leading quantity. For given envelope, only 
  results of leading quantity have true maximums and minimums, results of 
  other quantities are compatible with the leading quantity. 
6 Linear load: 
  Linear load has replaced the old uniform load (which is a special case 
  of the linear load).
7 A few bugs in the solver were removed and now you can solve one finite 
  element problems that are fully supported (no external degrees of freedom). 
  Additionally, when elements on elastic ground are used you can also solve 
  structures, which have no nodal supports at all.
8 Enriched hot-rolled library of I beams: 
  The library of hot-rolled profiles is richer and reorganized. 
  More European, Canadian and US hot-rolled beams are added into library.
9 Direct way to toggle element rotation release: You will find a new button 
  in the geometry toolbar, which allows you to release/fix element 
  rotations simply by clicking on the element ends. 
10 New - clear all supports button: 
   One button was missing on the supports toolbar in version 
   1.01 - the clear all supports button. This button is now added.
11 Educational version: There was almost no interest in the Lite version 
   and a big interest in the educational version. So the Lite version was 
   abandoned and the educational version introduced. 
   You can get the educational version free of charge, for personal and 
   non-professional use. 
12 Load and absolute coordinates: The load position on an element may be 
   defined in absolute coordinates as well as in relative coordinates.
13 Right mouse button support: The right mouse button is available in the 
   geometry workspace. This might save you a few clicks.
14 Element splitting command: If you select an element, you can command it 
   to split itself into prescribed number of elements of the same size. 
   This is very useful command if you are doing truss analysis.
15 More that 40 other minor enhancements: 
   Several spelling errors were corrected and a few buttons were modified. 
   The Apply and Help buttons on the property window are larger. 
   The Output settings and Options property pages has been a bit reorganized 
   and some options, which are related to the elastic ground and envelopes
   were added
16 Contnets of the current view may be copied into clipboard in enhanced
   metafile format.

Version 1.01
------------
1  Help bug that reported a missing DLL in the version 1.00 was removed.
   The DLL is not needed any more.
2  You can localize the output by editing the OutputString.db file. 
   The file holds strings that are used in the output. 
   You can create a new output group for a new language or 
   language variation.
3  The pictures of can be selected for ultimate and serviceability load
   cases independently. This gives you a more compact output.
4  The (&[FILE]) tag in the hedear/footer section diplays a file name only. 
   The (&[PATH]) tag now displays the full path of the file name.
5  Small values that should be zero but they are not (due to small 
   numerical error) can be filtered and converted into zeros.
6  You can fully describe the structure by adding a text section to the 
   output.
7  Another help file bug was removed. The bug prevented to open the help
   file on some Window95 systems.
