[dependabot]

Bumps abseil-cpp from 20260107.1 to 20260526.0.

Release notes

Sourced from abseil-cpp's releases.

Abseil LTS branch, May 2026

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.
