Cornico, can you point me to the changelog containing the originally released build 161 and the first update build 178? The previous updates 189 and 201 are there.
This is described in item 3 of the pinned FAQ post, which links to this post. The "small installer" (described in sections 2a and 2b of that post) should always fetch the latest update and install it over your current build. I'm also adding direct links for the "large installers" to section 2c if I know their location.
The release notes situation is not ideal. I'm surprised it's not at least being done in the same way as it was with SCS, as the first VP14 build 161 release notes document is in the same old format and much of the Madison team is the same. Subsequent builds releases notes were never added to it. I've been tempted to cobble together an unofficial update history post in this forum.
At least, as far as I know, I don't think there is any reason for anyone to roll back from build 211 to an earlier VP14 build, but there's all sorts of reasons why it's useful to know what was introduced or fixed when.
