- new function owl_strong_dragon() and new autohelper with the same name
- vital_chain() returns the max number of eyes
- no amalgamation around eye spaces with experimental_connections enabled
- eye spaces no longer modified by INHIBIT_CONNECTION with
  experimental_connections enabled
- bugfix in find_connection_moves()
- pattern classes Y and W introduced in conn.db to identify patterns
  which only applies with or without experimental_connections
- patterns with class e in conn.db changed to class I to better
  reflect current usage
- connection tuning
- improves DFA compile time by doing fewest possible large syncs 
- experimental_influence command line and configure option removed
- new flags dragons_known and is_territorial_influence in influence_data
- struct local_owl_data for speedup only holds eye space of relevant color
- owl_eyespace() and allies use only one eyespace
- dfa doesn't report symmetric patterns multiple times
- escape patterns in owl_defendpats.db given E classification
- owl_determine_life() not called during escape attempt
- only print debug output for eyes during owl reading if owl debug is on
- better traces for unused owl patterns
- --decide-connection also reports ko results
- bugfix in load_and_score_sgf_file()
- new test cases
- edge_block and double_atari_chain2 renamed to *_moves
- do_attack uses simple_ladder_attack when stackp > depth+10
- give up simple_ladder_attack below 20 ply when we are komaster
- unused caching code removed from attack? and defend?
- macros used to make reading code readable
- dragon field in struct eye_data removed
- new function find_eye_dragons() in optics.c
- dragon_invincible() and genus computation in make_dragons() revised
- play_connect_n() uses string_connect() and disconnect()
  unconditionally, no longer contingent on experimental_connections
- default value for experimental_connections reset to 0
- new command line option --decide-dragon-data
- consistency checking of replacement patterns reenabled for unstable line
- tuning
- new tests and sgf files
