Highlights:

-- Much better performance under Java 7 and later on OS X (but Apple's 
Java 1.6 is still the best performing solution, and the TurboVNC 
documentation now goes into detail as to why.)  Unfortunately, after 
talking to the Java developers, it does not appear that Java 9 is 
expected to resolve this situation in any way (although it should 
improve performance relative to Java 7/8 when client-side scaling is 
used.)  The TurboVNC documentation now de-emphasizes the use of the 
"OracleJava" flavor of our standalone client and recommends the 
"AppleJava" flavor whenever possible, even though this requires 
obtaining "Java for OS X" from Apple Support if installing on a more 
recent OS X release:  http://support.apple.com/kb/DL1572.  NOTE: despite 
the fact that the "OracleJava" flavor benchmarks somewhat slower than 
the "AppleJava" flavor, it's still somewhat faster than the TigerVNC 
FLTK-based viewer for OS X.  So in terms of preserving our "Turbo" 
reputation, we're safe.

-- Fixed a bug that was causing the toolbar to display incorrectly (or 
not at all) or to be overdrawn by the first few framebuffer updates when 
running under Java 7 and later.

-- Improved Java viewer performance under Windows (the viewer will now 
disable Direct3D Java 2D blitting and use the Windows GDI for blitting, 
when possible.  This is almost always faster.)

-- Improved native viewer performance under Windows (basically porting 
the same algorithmic fixes from the Unix and Java viewer code bases-- 
improves overall performance by about 5% or so.)

-- Other minor bug fixes

Performance-wise, this should be the final story for 2.0, unless some 
new information comes to light regarding extracting more performance 
under Java 7+ on OS X.

Remaining major stuff that I'm working on right now for 2.0:
-- Finishing client-side support for desktop resizing
-- Fixing Java full-screen issues under Linux
-- VeNCrypt support
-- Keyboard grab feature in Java viewer
