77 fetching (we don't care about the index). Fixes fetch errors.
78 - Add BB_GENERATE_MIRROR_TARBALLS option, set to 0 to make git fetches
79 faster at the expense of not creating mirror tarballs.

101 instead of BBHandler
102 - Fix getVarFlags bug in data_smart

106 - Cooker: Remove a debug message from the parsing loop to lower overhead
107 - Convert build.py exec_task to use getVarFlags
108 - Update shell to use cooker.buildFile
109 - Add StampUpdate event

114 updates
115 - Add BB_SCHEDULER variable/option ("completion" or "speed") controlling

128 - Add ability to fetchers to check URL validity without downloading
129 - Improve runtime PREFERRED_PROVIDERS warning message
130 - Add BB_STAMP_WHITELIST option which contains a list of stamps to ignore when
131 checking stamp dependencies and using a BB_STAMP_POLICY of "whitelist"
132 - No longer weight providers on the basis of a package being "already staged". This
133 leads to builds being non-deterministic.
134 - Flush stdout/stderr before forking to fix duplicate console output
135 - Make sure recrdeps tasks include all inter-task dependencies of a given fn
136 - Add bb.runqueue.check_stamp_fn() for use by packaged-staging
137 - Add PERSISTENT_DIR to store the PersistData in a persistent
138 directory != the cache dir.
139 - Add md5 and sha256 checksum generation functions to utils.py
140 - Correctly handle '-' characters in class names (#2958)
141 - Make sure expandKeys has been called on the data dictionary before running tasks
142 - Correctly add a task override in the form task-TASKNAME.
143 - Revert the '-' character fix in class names since it breaks things
144 - When a regexp fails to compile for PACKAGES_DYNAMIC, print a more useful error (#4444)
145 - Allow to checkout CVS by Date and Time. Just add HHmm to the SRCDATE.
146 - Move prunedir function to utils.py and add explode_dep_versions function
147 - Raise an exception if SRCREV == 'INVALID'
148 - Fix hg fetcher username/password handling and fix crash
149 - Fix PACKAGES_DYNAMIC handling of packages with '++' in the name
150 - Rename __depends to __base_depends after configuration parsing so we don't
151 recheck the validity of the config files time after time
152 - Add better environmental variable handling. By default it will now only pass certain
153 whitelisted variables into the data store. If BB_PRESERVE_ENV is set bitbake will use
154 all variable from the environment. If BB_ENV_WHITELIST is set, that whitelist will be
155 used instead of the internal bitbake one. Alternatively, BB_ENV_EXTRAWHITE can be used
156 to extend the internal whitelist.
157 - Perforce fetcher fix to use commandline options instead of being overriden by the environment
158 - bb.utils.prunedir can cope with symlinks to directoriees without exceptions
159 - use @rev when doing a svn checkout
160 - Add osc fetcher (from Joshua Lock in Poky)
161 - When SRCREV autorevisioning for a recipe is in use, don't cache the recipe
162 - Add tryaltconfigs option to control whether bitbake trys using alternative providers
163 to fulfil failed dependencies. It defaults to off, changing the default since this
164 behaviour confuses many users and isn't often useful.
165 - Improve lock file function error handling
166 - Add username handling to the git fetcher (Robert Bragg)
167 - Add support for HTTP_PROXY and HTTP_PROXY_IGNORE variables to the wget fetcher
168 - Export more variables to the fetcher commands to allow ssh checkouts and checkouts through
169 proxies to work better. (from Poky)
170 - Also allow user and pswd options in SRC_URIs globally (from Poky)
171 - Improve proxy handling when using mirrors (from Poky)
172 - Add bb.utils.prune_suffix function
173 - Fix hg checkouts of specific revisions (from Poky)
174 - Fix wget fetching of urls with parameters specified (from Poky)
175 - Add username handling to git fetcher (from Poky)
176 - Set HOME environmental variable when running fetcher commands (from Poky)
177 - Make sure allowed variables inherited from the environment are exported again (from Poky)
178 - When running a stage task in bbshell, run populate_staging, not the stage task (from Poky)
179 - Fix + character escaping from PACKAGES_DYNAMIC (thanks Otavio Salvador)
180 - Addition of BBCLASSEXTEND support for allowing one recipe to provide multiple targets (from Poky)

299 to avoid unpacking the sourceforge mirror page)
300 - Switch to a cow like data instance for persistent and non
301 persisting mode (called data_smart.py)
302 - Changed the callback of bb.make.collect_bbfiles to carry
