Abseil may occasionally release API-breaking changes. As noted in our
[Compatibility Guidelines][compatibility-guide], we will aim to provide a tool
to do the work of effecting such API-breaking changes, when absolutely
necessary.
These tools will be listed on the [C++ Upgrade Tools][upgrade-tools] guide on https://abseil.io.
For more information, the [C++ Automated Upgrade Guide][api-upgrades-guide]
outlines this process.
