tl;dr: the D install script is now able to install a specific
version of DUB.
./install.sh dmd-2.072.2,dub
./install.sh ldc-1.10.0,dub
This is mostly useful if you want to test an old version of a DMD
or LDC on a CI, but want to take advantage of all the stability
fixes in dub and thus use the latest dub.
The install.sh script is used on Travis too, so this will now
work on Travis too:
d: dmd-2.072.2,dub
But of course you can select a specific version too:
./install.sh dmd-2.072.2,dub.1.7.2
