WinUAE (1.5.3) released

• Huge memory leak when switching between RTG and native modes.
  
• Writing to disk images didn't work in some games.
  
• Configuration cache missing files in subdirectories.
  
• Random freeze when switching to fullscreen modes that are smaller than desktop resolution.
  
• Second and third mouse/firebutton handling fix (Aladdin, BC.Kid and more)

• "Always on top", "No taskbar button" and fullscreen color depth change works on the fly.
  
• OpenGL fullscreen fixed.
  
• Parallel/Serial/MIDI select menus and Input-panel bottom options didn't work correctly.
  
• System clock run slightly too fast or slow if chipset refresh rate was different than startup refresh rate (really old bug).
  
• OCS NTSC configuration defaulted to PAL refresh rate.
  
• Real PCMCIA SRAM card re-insert detection fixed.
  
• Fullscreen RTG 16-bit to 32-bit desktop windowed mode switch (CTRL+F12) color errors fixed.

• Basic file association settings added to GUI (.uae, .adf etc..)
  
• RTG vertical blank wait uses interrupts, no more busy waiting. Should improve performance in many fullscreen RTG games.
  
• Added RTG virtual refresh rate configuration to GUI.
  
• Added RTG refresh rate next to chipset refresh rate FPS counter.
  
• Undocumented OCS "scanline" feature emulated (Ode to Ramon I and II)
  
• Midline resolution change improvements (still far from perfect, Disposable Hero, Innovation Part 2)
  
• Only accept current latest OpenAL32.dll or newer (old versions can cause crashes during device enumeration)
  
• Improved emulation of reads from write-only custom registers (S.E.X. / Fantasys)
  
• Syncronize Clock stability improved.
