 ## Python 2 to 3 migration
 
-The path set when running builds now makes the `python` executable point to python 3,
-whereas on previous versions it pointed to python 2. If you still have python 2 scripts,
-you can change the shebang line to use `python2` explicitly. This only applies for
-scripts run directly from makefiles, or from soong genrules.
-
-In addition, `python_*` soong modules no longer allow python 2.
-
-Python 2 is slated for complete removal in V.
+Python 2 has been completely removed from the build. Please migrate any remaining usages to
+Python 3, and remove any version-specific properties from bp files.
 
 ## Stop referencing sysprop_library directly from cc modules

+The "generic_arm64_plus_armv7" product defines a non-hardware-specific arm64
+target with armv7 compatible arm32.  It is used for building CTS and other
+test suites for which the 32-bit binaries may be run on older devices with
+armv7 CPUs.
+
+It is not a product "base class"; no other products inherit
+from it or use it in any way.

+Change the output format for each flag.
+
+The argument to --format is a format string. Each flag will be a copy of this string, with certain
+placeholders replaced by attributes of the flag. The placeholders are
+
+  {package}
+  {name}
+  {namespace}
+  {description}
+  {bug}
+  {state}
+  {state:bool}
+  {permission}
+  {trace}
+  {trace:paths}
+  {is_fixed_read_only}
+  {is_exported}
+  {container}
+  {metadata}
+  {fully_qualified_name}
+
+Note: the format strings "textproto" and "protobuf" are handled in a special way: they output all
+flag attributes in text or binary protobuf format.
+
+Examples:
+
+  # See which files were read to determine the value of a flag; the files were read in the order
+  # listed.
+  --format='{fully_qualified_name} {trace}'
+
+  # Trace the files read for a specific flag. Useful during debugging.
+  --filter=fully_qualified_name:com.foo.flag_name --format='{trace}'
+
+  # Print a somewhat human readable description of each flag.
+  --format='The flag {name} in package {package} is {state} and has permission {permission}.'

+Limit which flags to output. If --filter is omitted, all flags will be printed. If multiple
+--filter options are provided, the output will be limited to flags that match any of the filters.
+
+The argument to --filter is a search query. Multiple queries can be AND-ed together by
+concatenating them with a plus sign.
+
+Valid queries are:
+
+  package:<string>
+  name:<string>
+  namespace:<string>

+  is_fixed_read_only:true|false
+  is_exported:true|false
+  container:<string>
+  fully_qualified_name:<string>
+
+Note: there is currently no support for filtering based on these flag attributes: description,
+trace, metadata.
+
+Examples:
+
+  # Print a single flag:
+  --filter=fully_qualified_name:com.foo.flag_name
+
+  # Print all known information about a single flag:
+  --filter=fully_qualified_name:com.foo.flag_name --format=textproto
+
+  # Print all flags in the com.foo package, and all enabled flags in the com.bar package:
