1 Changes in BitBake 1.8.x:
2 - Fix -f (force) in conjunction with -b

5 - Change parseConfigurationFile so it works on real data, not a copy
6 - Handle 'base' inherit and all other INHERITs from parseConfigurationFile
8 - Fix getVarFlags bug in data_smart
9 - Optmise cache handling by more quickly detecting an invalid cache, only
10 saving the cache when its changed, moving the cache validity check into
11 the parsing loop and factoring some getVar calls outside a for loop
12 - Cooker: Remove a debug message from the parsing loop to lower overhead
13 - Convert build.py exec_task to use getVarFlags
14 - Update shell to use cooker.buildFile
15 - Add StampUpdate event

22 the way bitbake schedules tasks
23 - Add BB_STAMP_POLICY variable/option ("perfile" or "full") controlling
24 how extensively stamps are looked at for validity
25 - When handling build target failures make sure idepends are checked and

35 checking stamp dependencies and using a BB_STAMP_POLICY of "whitelist"

37 leads to builds being non-deterministic.
