The version 1.0a of Tennis Elbow 2005 has just been released.
Here the improvements:

• 1 new court, the "indoor hard" (more slow than "indoor synthetic", and a bit faster than "outdoor synthetic")
• new sound FX (French announcements, footsteps)
• 1 new difficulty level, between "easy" and "medium"
• more realistic simulation of scores in the World Tour
• a lot of bugs fixed since the initial 1.0 release (most of them were already fixed in the previous version available from the site)
• Spanish translation added
• a few little tunings

Difficulty levels have been renamed:

• “Very easy” becomes “Beginner”
• “Easy” becomes “Club”
• “Medium” becomes “Pro”
• “Hard” becomes “Master”
