Hi all, 

TXR 199 [1] is out. Binaries at Bintray [2]. 

 	* New compiler optimizations, particularly access to global lexical
variables.

	* File compiler now conveniently propagates hash bang line from source
file to compiled file, and that hash bang operation is supported in
compiled files.

	* Top-level forms treated more incrementally by evaluator and compiler.
This means that for instance we can compile (progn (defmacro foo ())
(foo)) as a top-level form. The sub-forms are expanded and compiled
separately and sequence.
 	* New functions in library: random-float, signum and others.
Floating-point rounding control exposed, if available in host platform. 
 	* Fixed bug in compiler's treatment of nil test in (for ...) loop. 

	* Numerous doc improvements.

 Cheers ...
