11 Changes in BitBake 1.8.12:
12 - Fix -f (force) in conjunction with -b
13 - Fix exit code for build failures in --continue mode
14 - Fix git branch tags fetching
15 - Change parseConfigurationFile so it works on real data, not a copy
16 - Handle 'base' inherit and all other INHERITs from parseConfigurationFile
18 - Fix getVarFlags bug in data_smart
19 - Optmise cache handling by more quickly detecting an invalid cache, only
20 saving the cache when its changed, moving the cache validity check into
21 the parsing loop and factoring some getVar calls outside a for loop
22 - Cooker: Remove a debug message from the parsing loop to lower overhead
23 - Convert build.py exec_task to use getVarFlags
24 - Update shell to use cooker.buildFile
25 - Add StampUpdate event
26 - Convert -b option to use taskdata/runqueue
27 - Remove digraph and switch to new stamp checking code. exec_task no longer
29 - Make fetcher timestamp updating non-fatal when permissions don't allow
31 - Add BB_SCHEDULER variable/option ("completion" or "speed") controlling
32 the way bitbake schedules tasks
33 - Add BB_STAMP_POLICY variable/option ("perfile" or "full") controlling
34 how extensively stamps are looked at for validity
35 - When handling build target failures make sure idepends are checked and
36 failed where needed. Fixes --continue mode crashes.
37 - Fix problems with recrdeptask handling where some idepends weren't handled
39 - Work around refs/HEAD issues with git over http (#3410)
40 - Add proxy support to the CVS fetcher (from Cyril Chemparathy)
41 - Improve runfetchcmd so errors are seen and various GIT variables are exported
42 - Add ability to fetchers to check URL validity without downloading
43 - Improve runtime PREFERRED_PROVIDERS warning message
44 - Add BB_STAMP_WHITELIST option which contains a list of stamps to ignore when
45 checking stamp dependencies and using a BB_STAMP_POLICY of "whitelist"
46 - No longer weight providers on the basis of a package being "already staged". This
47 leads to builds being non-deterministic.
48 - Flush stdout/stderr before forking to fix duplicate console output
49 - Make sure recrdeps tasks include all inter-task dependencies of a given fn
50 - Add bb.runqueue.check_stamp_fn() for use by packaged-staging
51 - Add PERSISTENT_DIR to store the PersistData in a persistent
52 directory != the cache dir.
53 - Add md5 and sha256 checksum generation functions to utils.py
54 - Make sure Build Completed events are generated even when tasks fail
55 - Correctly handle '-' characters in class names (#2958)
56 - Make sure expandKeys has been called on the data dictonary before running tasks
57 - Correctly add a task override in the form task-TASKNAME.
58 - Revert the '-' character fix in class names since it breaks things
59 - When a regexp fails to compile for PACKAGES_DYNAMIC, print a more useful error (#4444)
60 - Allow to checkout CVS by Date and Time. Just add HHmm to the SRCDATE.
61 - Move prunedir function to utils.py and add explode_dep_versions function
62 - Raise an exception if SRCREV == 'INVALID'
63 - Fix hg fetcher username/password handling and fix crash
64 - Fix PACKAGES_DYNAMIC handling of packages with '++' in the name
65 - Rename __depends to __base_depends after configuration parsing so we don't
66 recheck the validity of the config files time after time
67 - Add better environmental variable handling. By default it will now only pass certain
68 whitelisted variables into the data store. If BB_PRESERVE_ENV is set bitbake will use
69 all variable from the environment. If BB_ENV_WHITELIST is set, that whitelist will be
70 used instead of the internal bitbake one. Alternatively, BB_ENV_EXTRAWHITE can be used
71 to extend the internal whitelist.
72 - Perforce fetcher fix to use commandline options instead of being overriden by the environment
73 - use @rev when doing a svn checkout
74 - Add osc fetcher (from Joshua Lock in Poky)
75 - When SRCREV autorevisioning for a recipe is in use, don't cache the recipe
76 - Add tryaltconfigs option to control whether bitbake trys using alternative providers
77 to fulfil failed dependencies. It defaults to off, changing the default since this
78 behaviour confuses many users and isn't often useful.
79 - Improve lock file function error handling
80 - Add username handling to the git fetcher (Robert Bragg)
81 - Add support for HTTP_PROXY and HTTP_PROXY_IGNORE variables to the wget fetcher
82 - Export more variables to the fetcher commands to allow ssh checkouts and checkouts through
83 proxies to work better. (from Poky)
84 - Also allow user and pswd options in SRC_URIs globally (from Poky)
85 - Improve proxy handling when using mirrors (from Poky)

109 fetching (we don't care about the index). Fixes fetch errors.

111 faster at the expense of not creating mirror tarballs.
112 - SRCREV handling updates, improvements and fixes from Poky
113 - Add bb.utils.lockfile() and bb.utils.unlockfile() from Poky
