-- f6d1ddef9a38e3fb8492181bf1a7a006b7f2145d by Abseil Team <absl-team@google.com>: Update the implementation of `operator<<` in Status to use `ToString(StatusToStringMode::kWithEverything)` PiperOrigin-RevId: 380740880 -- 5f13b20c4b85c1c6e94b69c74f80f8f3f3941747 by Derek Mauro <dmauro@google.com>: Update Docker images This also disables the Clang/libstdc++/C++20 combo as it seems that the latest libstdc++ is relying on C++20 Concepts to a greater extent than Clang supports. PiperOrigin-RevId: 380714572 -- f8f4dee12cfd02559bf741ad6b06f10ac0c48c73 by Abseil Team <absl-team@google.com>: Fix shadow member warnings in randen_hwaes.cc These happen when attempting to use abseil in github.com/google/benchmark. The project sets -Wshadow. The warning is due to the name of the Vector128 ctor parameter. Using v instead, which I see used elsewhere (e.g. line 290) PiperOrigin-RevId: 380704197 -- 2e1a09e9cb1239485715acb4828d9b4799fcfbb5 by Tom Manshreck <shreck@google.com>: Add more precise documentation for AbslParseFlag declarations in the Time API PiperOrigin-RevId: 380649107 -- 153e5f7a960c03e4161c03737a0ff18ba377ff73 by Evan Brown <ezb@google.com>: Make the number of control bytes a constant. We use a constexpr function because we need to support C++11, which doesn't have inline variables. The motivation is to avoid future bugs where the number changes and we forget to update all the places it's used. This CL should be a no-op.
