------------------------------------
Version: 2.4.2 - July 27, 2012
------------------------------------
- One bug fixed in CL_rot_quat2axAng (which sometimes returned a wrong rotation
angle). 

- One new demo (in the "relative motion" section). 

- Improvement/adaptation of the functions: CL_rot_quat2axAng, CL_rot_axAng2quat,
CL_rot_quatSlerp. 
  
- The CelestLab menu has been extended. 


------------------------------------
Version: 2.4.1 - July 20, 2012
------------------------------------
- A few minor changes, mostly the update of the detailed changelog 
  that was not exact. 
  
- 2 new demos (relative motion and Hohmann <-> continuous thrust)

- Improvement of the functions: CL_cw_Mmatrix and CL_cw_Nmatrix


------------------------------------
Version: 2.4.0 - July 10, 2012
------------------------------------
This version is a "minor" version that includes a few improvements.  
The main features (in comparison with 2.3.0) are: 

- 11 new functions:
  CL_man_applyDvKep, CL_man_dvApsidesLine, CL_man_dvBiElliptic,
CL_man_dvHohmann, 
  CL_man_dvHohmannG, CL_man_dvIncRaanCirc, CL_man_dvInc, CL_man_dvSma
  CL_gm_orbSphTriangle, CL_op_equatorialSwath, CL_integrate, CL_home

  The interfaces of the new maneuver functions (CL_man_dv...) are such that: 
  - the delta-v (sum of norms) is systematically returned as 1st argument 
  - the delta-v vectors are now returned in cartesian coordinates
  
- 7 new demos
  (about: solar zenith angle, satellite local time, Sun elevation on earth,
inclination maneuvers)
  
- A few functions improved: 
  CL_dat_utc2tai, CL_dat_tai2utc... 
   
- A few bugs fixed:
  CL_man_hohmannG, CL_man_inclination, CL_man_lambert, CL_ex_lyddaneInfos. 
  A major bug in CL_rot_angularVelocity had an impact on some frame
transformations (limited impact in practice). 
  
- Minor interface changes: 
  "obl" argument in CL_fr_ter2topoN and CL_fr_topoN2ter becomes
"obla", 
  "conv" argument in some frame conversion functions changed to
"conv_iers". 
 
- Some functions from the "Utilities" folder have been moved to a new
folder: "Math". 
  The CelestLab overview help page now contains links to external pages about
CelestLab. 

- A total of 16 functions are now deprecated.  
  They will issue a warning message in CelestLab v3.x,
  and will be permanently deleted in CelestLab v4.0. 
  The deprecated functions have been grouped in a section (library) called
"DEPRECATED".
