R01–R18: the bundled packages, built by hand in BEAUti
BEAST 2.8.0 ships with bModelTest, ORC, SA, StarBeast3 and CCD. Six new combinations test them; twelve from the rc2 round are rebuilt because they did not pass on rc2 or changed since. Everything is built with the rc3 installer and its bundled packages, and compared with BEAST 2.7.9 with the same packages. The plan is in ASSIGNMENTS.md, "rc3 round".

Detail and next step
Before the round
rc3 is released with the five packages bundled and seeded on first launch (beast3#248).
BEAST 2.7.9 has the 2.7 versions of bModelTest, ORC, SA, StarBeast3 and CCD installed, plus SSM for the GTR comparisons. Check that SA's 2.7 package ships bears.nex.
The automated package check has run on rc3: build, unit tests, examples, BEAUti scenarios and TreeAnnotator with CCD for all five packages.
What is different from the rc2 round
Everything is built with the rc3 installer as shipped; nothing is installed through the package manager in BEAST 3.
The 2.7.9 side of the GTR combinations (R01, R03, R09, R10) uses SSM's GTR, which has the same Dirichlet prior on the rates as BEAUti 3's GTR (beast3#251).
Default priors differ between the versions. rc3's BEAUti uses wide log-normal default priors (beast3#208); the matching change for BEAUti 2.7, BeastFX#111, is not merged. So a model built with defaults gets different priors in the two versions: set every prior by hand to match the 2.7.9 XML, and record it.
R18 is not built in BEAUti: TreeAnnotator with CCD0 and CCD1 on the same tree file in both versions must give identical summary trees.
The 18 rc2 combinations that passed are not rebuilt by hand; their BEAST 3 XMLs are rerun on rc3 and compared automatically.
