Details
As shown in !42, in the current master branch TAUOLA FSR and PHOTOS are both ON by default (with different photon energy cut-off values), so we are generating FSR twice. We observe that, with TAUOLA FSR ON and PHOTOS OFF, we obtain similar results as with TAUOLA FSR OFF and PHOTOS ON (after equalising the photon energy cut-off value). The latter is now the default configuration. When compared with master branch we observe different results for the tests after the modifications in this differential, but these are expected.

Event Timeline
Tests for leptonic tau decays in tauola show no significant differences after implementation of these changes.
IIRC from the discussion in !42, that's not quite right. Rather there are differences but they are as expected, i.e. we've stopped doubling-up the radiation in certain decays. Is that right?
So what I meant is that tests with Tauola radiation ON and PHOTOS OFF give similar results as Tauola radiation OFF and PHOTOS ON, as shown in !42. Compared with master branch the tests should give different results, as expected since now we are not doing double generation of FSR, as shown also in !42.
