v8.7.0

This release contains a fix for ISA-2025-001 .

This version addresses a security vulnerability in IBC-go's deserialisation of acknowledgements and we strongly encourage everyone in the affected versions to update their chain immediately. This patch is not state-breaking, so chains can upgrade in a rolling manner. This does not have to be a co-ordinated upgrade. However, validators should upgrade as soon as possible when the release is made available. If the vulnerability is exploited before 2/3 is patched, the chain will halt.
