The TinyOS 1.1.4 February 2004 CVS Snapshot is online. 

The February 2004 snapshot features:

- Tython: Tython is a TOSSIM scripting environment that uses a Java
implementation of the Python programming language. Tython allows users to
write scripts to do things such as dynamically move motes within a
simulation, inject packets into a simulation, and inspect the internal state
of the simulation. 

Tython allows full access to the existing Java TinyOS toolchain, so users
can write a piece of TinyOS messaging code, generate a Java packet object
from it using mig, then use Tython to inject those packets into a running
simulation. 

Tython is integrated with the TinyViz environment; this means that, for
example, if a script makes a mote move, a user can see the movement in the
TinyViz visualization and its radio connectivity will be updated as
expected. TinyViz and Tython can be run separately from one another.

You can find out more about Tython in doc/tython.

installation info. 

-------------------------

The intention behind these monthly snapshots is to get the latest code to
the community without requiring developers to maintain an up-to-date CVS
tree. A CVS snapshot release is very nearly that: a snapshot of the CVS tree
in a convenient-to-install package. If you'd like the bleeding edge code and
don't mind the inherent risks, upgrade to the snapshot releases as they
become available.  If stability is important to you, you might want to stay
with the fully-tested releases or at least fully-test your apps before
migrating wholesale to a snapshot release. 

In the upcoming March 2005 snapshot:

- 802.15.4 radio stack which will be used for the Telos mote and Crossbow's
MicaZ mote
