- 3. _C_h_a_n_g_e_s__a_n_d__A_d_d_i_t_i_o_n_s
-
- +o Starting with _I_r_i_x _6._4, the default format for 32-bit
- compiled objects is N32. Given this, the *.sw32
- subsystems have been merged into the *sw subsystems.
-
- +o _I_r_i_x _6._5 is based on the _X_1_1_R_6._3 release from The Open
- Group. The _I_r_i_x _6._2 release was based on _X_1_1_R_6.
-
- +o New R6 functionality supported in Irix 6.5 includes the
- RECORD extension, the XSYNC extension, the XC-MISC
- extension and the LBX extension.
-
- +o There are no plans to support the X Imaging Extension
- (XIE) and the MIT-KERBEROS-5 authorization scheme which
- were released with X11R6.
-
- +o _I_r_i_x _6._5 has full support for the new X Consortium
- double-buffering extension, DBE.
-
- +o Starting with _I_r_i_x _6._5, libX11 and libXt are thread-
- safe. See the man page for XInitThreads for details on
- how to program X with threads.
-
- +o _I_r_i_x _6._5 supports a new version (rev. 1.2) of the SGI-
- only extension, XSGIvc, for video control of the
- graphics back end. Existing XSGIvc applications should
- still run on an _I_r_i_x _6._5 system. See "man XSGIvc" for
- details.
-
- +o _I_r_i_x _6._5 no longer supports execution of NMBX double-
- buffered applications (NMBX was an SGI-only double-
- buffering extension).
-
- +o _I_r_i_x _6._5 supports displaying MBX applications, but no
- longer supports building such applications (MBX was a
- proposed X extension that was never adopted, and that
- has been replaced by the officially supported DBE
- extension).
-
- +o Source code examples for X input device clients and
- drivers are now found in the "X11 Source Code Examples"
- (_x__d_e_v._s_r_c._e_x_a_m_p_l_e_s) subsystem.
-
- +o Stereo-capable visuals are now supported on O2.
