New dated version.

Abseil LTS 20260526.0
What's New
    status_macros.h: Helper macros and methods to return and propagate errors with absl::Status.
    absl::StatusBuilder: A builder type that implicitly converts to absl::Status and absl::StatusOr<T> that helps add additional information.
    absl::SourceLocation: A type that provides source-code location info for C++17 and later. It differs from std::source_location in several ways. See source_location.h for more information.
    absl::ClockInterface: An abstract interface representing a clock, allowing decoupling code that uses time from the code that creates a point in time. Useful for injecting clocks into interfaces, especially for testing purposes.
    absl::SimulatedClock: A concrete clock implementation that does not "tick" on its own. Useful for manipulating time for testing purposes.
    absl::AnySpan: A type that provides a view of any random access container.
    absl::optional_ref: A type that provides a std::optional-like interface around T*.
    absl::bind_back: A drop-in replacement for C++23's std::bind_back().
    absl::CopyCordToSpan: A safer way to copy the contents of an absl::Cord to a buffer.
    absl::HighPrecision: An absl::StrCat formatter that produces strings that would parse to the exact original floating point value (except in the case of NaNs).
    throw_delegate.h: Helper functions that allow throwing exceptions consistently from anywhere without risking ODR violations.

Breaking Changes
    For GCC users, Abseil now requires at least GCC 10 following Google's Foundational C++ Support Policy. See this table for a list of currently supported versions compilers, platforms, and build tools.
    Many pre-C++17 polyfill types are marked deprecated. Users should migrate to the std:: equivalent.
