The current release process describes a sort of handshake between the RTL and SW repositories that means the repo caliptra-rtl may not be tagged for a major release until after the SW repo has consumed the RTL and published its own code. Software releases often lag RTL readiness (in particular, since ROM release precedes Runtime firmware).
The proposed process update allows RTL to be tagged when ready. Creation of a new RTL branch allows the Firmware team to consume a deterministic snapshot of the RTL, while the hardware team advances towards the next feature set on the main branch. This also resolves a current issue where the RTL consumed by Firmware as a submodule may diverge from the actual versioned RTL release.
