  <summary>Security update for abseil-cpp, grpc, opencensus-proto, protobuf, python-abseil, python-grpcio, re2</summary>
  <description>This update for abseil-cpp, grpc, opencensus-proto, protobuf, python-abseil, python-grpcio, re2 fixes the following issues:

abseil-cpp was updated to:

Update to 20230802.1:

* Add StdcppWaiter to the end of the list of waiter implementations

Update to 20230802.0

What's New:

* Added the nullability library for designating the expected
    nullability of pointers. Currently these serve as annotations
    only, but it is expected that compilers will one day be able
    to use these annotations for diagnostic purposes.
  * Added the prefetch library as a portable layer for moving data
    into caches before it is read.
  * Abseil's hash tables now detect many more programming errors
    in debug and sanitizer builds.
  * Abseil's synchronization objects now differentiate absolute
    waits (when passed an absl::Time) from relative waits (when
    passed an absl::Duration) when the underlying platform supports
    differentiating these cases. This only makes a difference when
    system clocks are adjusted.
  * Abseil's flag parsing library includes additional methods that
    make it easier to use when another library also expects to be
    able to parse flags.
  * absl::string_view is now available as a smaller target,
    @com_google_absl//absl/strings:string_view, so that users may
    use this library without depending on the much larger
    @com_google_absl//absl/strings target.

Update to 20230125.3

Details can be found on:

https://github.com/abseil/abseil-cpp/releases/tag/20230125.3

Update to 20230125.2

What's New:

The Abseil logging library has been released. This library
    provides facilities for writing short text messages about the
    status of a program to stderr, disk files, or other sinks
    (via an extension API). See the logging library documentation
    for more information.
      An extension point, AbslStringify(), allows user-defined types
    to seamlessly work with Abseil's string formatting functions
    like absl::StrCat() and absl::StrFormat().
      A library for computing CRC32C checksums has been added.
      Floating-point parsing now uses the Eisel-Lemire algorithm,
    which provides a significant speed improvement.
      The flags library now provides suggestions for the closest
    flag(s) in the case of misspelled flags.
      Using CMake to install Abseil now makes the installed artifacts
    (in particular absl/base/options.h) reflect the compiled ABI.

Breaking Changes:

Abseil now requires at least C++14 and follows Google's Foundational
    C++ Support Policy. See this table for a list of currently supported
    versions compilers, platforms, and build tools.
      The legacy spellings of the thread annotation macros/functions
    (e.g. GUARDED_BY()) have been removed by default in favor of the
    ABSL_ prefixed versions (e.g. ABSL_GUARDED_BY()) due to clashes with
    other libraries. The compatibility macro ABSL_LEGACY_THREAD_ANNOTATIONS
    can be defined on the compile command-line to temporarily restore these
    spellings, but this compatibility macro will be removed in the future.

Known Issues

The Abseil logging library in this release is not a feature-complete
    replacement for glog yet. VLOG and DFATAL are examples of features
    that have not yet been released.

Update to version 20220623.0

What's New:

* Added absl::AnyInvocable, a move-only function type.
  * Added absl::CordBuffer, a type for buffering data for eventual inclusion an
    absl::Cord, which is useful for writing zero-copy code.
  * Added support for command-line flags of type absl::optional&lt;T&gt;.

Breaking Changes:

* CMake builds now use the flag ABSL_BUILD_TESTING (default: OFF) to control
    whether or not unit tests are built.
  * The ABSL_DEPRECATED macro now works with the GCC compiler. GCC users that
    are experiencing new warnings can use -Wno-deprecated-declatations silence
	the warnings or use -Wno-error=deprecated-declarations to see warnings but
	not fail the build.
  * ABSL_CONST_INIT uses the C++20 keyword constinit when available. Some
    compilers are more strict about where this keyword must appear compared to
	the pre-C++20 implementation.
  * Bazel builds now depend on the bazelbuild/bazel-skylib repository.
    See Abseil's WORKSPACE file for an example of how to add this dependency.

Other:

* This will be the last release to support C++11. Future releases will require at least C++14.

grpc was updated to 1.60:

  * Fix C# optional field reflection when there are regular fields too
  * Fix parsing negative Int32Value that crosses segment boundary
  Javascript:
  * JS: parse (un)packed fields conditionally

Update to version 3.13.0
  PHP:
  * The C extension is completely rewritten. The new C extension has significantly
    better parsing performance and fixes a handful of conformance issues. It will
    also make it easier to add support for more features like proto2 and proto3 presence.
  * The new C extension does not support PHP 5.x. PHP 5.x users can still use pure-PHP.
  C++:
  * Removed deprecated unsafe arena string accessors
  * Enabled heterogeneous lookup for std::string keys in maps.
  * Removed implicit conversion from StringPiece to std::string
  * Fix use-after-destroy bug when the Map is allocated in the arena.

    fields.
  Python:
  * JSON format conformance fixes:

    in EnumTypeWrapper.
  Java:
  * Fixed a bug where setting optional proto3 enums with setFooValue() would
    not mark the value as present.
  * Add Subtract function to FieldMaskUtil.
  C#:
  * Dropped support for netstandard1.0 (replaced by support for netstandard1.1).
    This was required to modernize the parsing stack to use the `Span&lt;byte&gt;`
    type internally
  * Add `ParseFrom(ReadOnlySequence&lt;byte&gt;)` method to enable GC friendly
    parsing with reduced allocations and buffer copies
  * Add support for serialization directly to a `IBufferWriter&lt;byte&gt;` or
    to a `Span&lt;byte&gt;` to enable GC friendly serialization.
    The new API is available as extension methods on the `IMessage` type
  * Add `GOOGLE_PROTOBUF_REFSTRUCT_COMPATIBILITY_MODE` define to make
    generated code compatible with old C# compilers (pre-roslyn compilers
    from .NET framework and old versions of mono) that do not support
    ref structs. Users that are still on a legacy stack that does
    not support C# 7.2 compiler might need to use the new define
    in their projects to be able to build the newly generated code
  * Due to the major overhaul of parsing and serialization internals,
    it is recommended to regenerate your generated code to achieve the best
    performance (the legacy generated code will still work, but might incur
    a slight performance penalty).

Update to version 3.12.3; notable changes since 3.11.4:

Protocol Compiler:

    protos where this is possible.
  Ruby:

Update to version 3.11.4; notable changes since 3.9.2:

* C++: Make serialization method naming consistent
  * C++: Moved ShutdownProtobufLibrary() to message_lite.h. For
         backward compatibility a declaration is still available
         in stubs/common.h, but users should prefer message_lite.h
  * C++: Removed non-namespace macro EXPECT_OK()
  * C++: Removed mathlimits.h from stubs in favor of using
         std::numeric_limits from C++11
  * C++: Support direct pickling of nested messages
  * C++: Disable extension code gen for C#
  * C++: Switch the proto parser to the faster MOMI parser

         will now be reported
  * C++: Add proto2::util::RemoveSubranges to remove multiple
         subranges in linear time
  * C++: Support 32 bit values for ProtoStreamObjectWriter to Struct
  * C++: Removed the internal-only header coded_stream_inl.h and
         the internal-only methods defined there
  * C++: Enforced no SWIG wrapping of descriptor_database.h
         (other headers already had this restriction)
  * C++: Implementation of the equivalent of the MOMI parser for
         serialization. This removes one of the two serialization
         routines, by making the fast array serialization routine
         completely general. SerializeToCodedStream can now be
         implemented in terms of the much much faster array
         serialization. The array serialization regresses slightly,
         but when array serialization is not possible this wins big

  * Java: Remove the usage of MethodHandle, so that Android users
          prior to API version 26 can use protobuf-java

          top level package. This will eventually replace
          JsonFormat.TypeRegistry
  * Java: Add Automatic-Module-Name entries to the Manifest
  * Python: Add float_precision option in json format printer
  * Python: Optionally print bytes fields as messages in unknown
            fields, if possible
  * Python: Experimental code gen (fast import protobuf module)
            which only work with cpp generated code linked in

  * JavaScript: Create dates.ts and time_of_days.ts to mirror Java
                versions. This is a near-identical conversion of
                c.g.type.util.{Dates,TimeOfDays} respectively
  * JavaScript: Migrate moneys to TypeScript
  * PHP: Increase php7.4 compatibility
  * PHP: Implement lazy loading of php class for proto messages

  * writeTo() method in ByteString can now write a substring to
  * java_generate_equals_and_hash can now be used with the
  * A new C++-backed extension module (aka "cpp api v2") that
    replaces the old ("cpp api v1") one. Much faster than the
    pure Python code. This one resolves many bugs and is
  mosh reqires it

python-abseil was udpated:

version update to 1.4.0
  New:
    (testing) Added @flagsaver.as_parsed: this allows saving/restoring flags
    using string values as if parsed from the command line and will also reflect
    other flag states after command line parsing, e.g. .present is set.
  Changed:
    (logging) If no log dir is specified logging.find_log_dir() now falls back
    to tempfile.gettempdir() instead of /tmp/.
  Fixed:
    (flags) Additional kwargs (e.g. short_name=) to DEFINE_multi_enum_class
    are now correctly passed to the underlying Flag object.

version update to 1.2.0
  *   Fixed a crash in Python 3.11 when `TempFileCleanup.SUCCESS` is used.
  *   `Flag` instances now raise an error if used in a bool context. This prevents
      the occasional mistake of testing an instance for truthiness rather than
      testing `flag.value`.
  *   `absl-py` no longer depends on `six`.

Update to version 1.0.0 
  * absl-py no longer supports Python 2.7, 3.4, 3.5. All versions
    have reached end-of-life for more than a year now.
  * New releases will be tagged as vX.Y.Z instead of pypi-vX.Y.Z in
    the git repo going forward.

- Release notes for 0.15.0

* (testing) #128: When running bazel with its --test_filter=
    flag, it now treats the filters as unittest's -k flag in Python
    3.7+.

- Release notes for 0.14.1

* Top-level LICENSE file is now exported in bazel.

- Release notes for 0.14.0

* #171: Creating argparse_flags.ArgumentParser with
    argument_default= no longer raises an exception when other
    absl.flags flags are defined.
  * #173: absltest now correctly sets up test filtering and fail
    fast flags when an explicit argv= parameter is passed to
    absltest.main.

- Release notes for 0.13.0
  * (app) Type annotations for public app interfaces.
  * (testing) Added new decorator @absltest.skipThisClass to
    indicate a class contains shared functionality to be used as a
    base class for other TestCases, and therefore should be
    skipped.
  * (app) Annotated the flag_parser paramteter of run as
    keyword-only. This keyword-only constraint will be enforced at
    runtime in a future release.
  * (app, flags) Flag validations now include all errors from
    disjoint flag sets, instead of fail fast upon first error from
    all validators. Multiple validators on the same flag still
    fails fast.
- Release notes for 0.12.0
  * (flags) Made EnumClassSerializer and EnumClassListSerializer
    public.
  * (flags) Added a required: Optional[bool] = False parameter to
    DEFINE_* functions.
  * (testing) flagsaver overrides can now be specified in terms of
    FlagHolder.
  * (testing) parameterized.product: Allows testing a method over
    cartesian product of parameters values, specified as a
    sequences of values for each parameter or as kwargs-like dicts
    of parameter values.
  * (testing) Added public flag holders for --test_srcdir and
    --test_tmpdir. Users should use absltest.TEST_SRCDIR.value and
    absltest.TEST_TMPDIR.value instead of FLAGS.test_srcdir and
    FLAGS.test_tmpdir.
  * (flags) Made CsvListSerializer respect its delimiter argument.
