[gnugo-devel] GNU Go 3.1.27

[Daniel Bump]

GNU Go 3.1.27 is now available at:

http://www.gnu.org/software/gnugo/devel.html

The CVS tag is rel-3-1-27.

This release gives identical behavior to 3.1.26 on the regressions
but includes an important bugfix which makes it run much faster
in actual games. This is the correction of a bug that was
introduced in 3.1.10 causing the owl code to recompute moves
much more frequently than necessary.

gunnar_1_27.2. Important bugfix and speedup. 
bump_1_27.1. Semeai bugfix, new DEBUG_OWL_PERSISTENT_CACHE and debug flag help.
teun_1_27.1. Careful about liberties in readconnect.c. 
trevor_1_27.7. Komaster scheme and more. 
trevor_1_27.8. Needed with trevor_1_27.7. 
gunnar_1_27.1. init_owl(). 
vcrepair_1_27.1. Defaults for config.vc(in) 
trevor_1_27.1. Reorders conditions in revise_semeai. 
trevor_1_27.3. Header file reorganization. 
trevor_1_27.4a Read attack tuning. 
trevor_1_27.5. VC builds precompiled headers. 
trevor_1_27.6. No robots.
