+[[TinyOS]] release 2.1.1-4.4 is available.
+
+* Revert to how 2.1.0 creates TOSMAKE_PATH. It adds TINYOS_MAKE_PATH to the
+ end, allowing local code to override system code. 2.1.1 adds TINYOS_MAKE_PATH
+ to the beginning, preventing local overrides.
+* Various USCI fixes.
+* Provide new system components SharedArbiterC and SharedSplitControlC. We use
+ these to activate subsystems ony when needed, where the subsystems are usable
+ by multiple higher-level components concurrently.
+* TinyOS by default presumes that on boot UartStream interface providers have
+ the receive interrupt active. We had presumed that it was better to allow
+ the code to specifically activate the interrupt when it was ready to handle
+ input data. TMI patch 4.4 now works like official TinyOS.
+* Remove bitfield warning in msp430 adc12 when using GCC 4.x.
+* Provide new interfaces ReadRefNow, Write and WriteNow.
+
+TMI has also updated to nesc-1.3.2. A big thank you to idgay, who fixed bug
+[3013497](http://sourceforge.net/tracker/?func=detail&aid=3013497&group_id=56288&atid=480036)
+that was preventing us from using nescc with GCC on Ubuntu Linux. Using the
+nx_ types of nescc to define cross platform data structures in header files
+shared between TinyOS targets and other systems is much more elegant than
+managing a parallel set of definitions defined programmatically by function
+calls to the TinyOS C-SDK.
