Description
Prior to changeset 162 the helicity was flipped for any neutral resonance in the decay of a neutral particle. Now the flip no longer occurs in flavour-specific decays. This is the preferred setup and does not affect any physical results but it does contribute a pi phase flip to some odd-spin resonances (for example K*(892)0 in Bs->D0Kpi). Therefore results are not necessarily comparable between fits run before and after this changeset. This change occurred between v2r2 and v3r0.

To close this bug (required to release v3r0) the release notes need to be updated to very explicitly mention this change.
