Titler Pro 4 does not work with V14.  You have to downgrade to V3 for it to function.  Titler Pro 1 does work.

Vegas Pro 13.0 Release notes

Abridged Vegas Pro 14.0 release notes

p.s.: I am also interested in what has changed in DVD-A Pro (currently running v6)

Nothing has changed in DVDA other than branding.

V-14 has no Dolby AC3 codec

It does but it's the Dolby AC-3 Studio codec and the files won't work in DVDA without re-encoding. If you have VP12 and DVDA there is a workaround to get the Pro codec working in VP14.

V-14 has its own mov codec which works well

But only for ProRes 422.

V-14 has no cuda selection in my machine (GFX 8800 512)

The CUDA selection is still available in the internal preferences, but support is unchanged so it is still incompatible with GPUs later than GTX 580.

V-14 in my case had to have V-12 un-installed before installing V-14 to function.

Not in my case, and it's the first time I have heard that is necessary. I have VP10, 12, 13, and 14 all installed.

There are also the tablet features and project sharing stuff introduced in VP13 and possibly the toolbar icon changes are still there. TBH, VP13 didn't add very much that was a must have for me but I did upgrade to it for $149 (hint! hint!).

I am a Vegas Pro v12 user and I am trying to piece together the major additions in moving to Vegas Pro v14. I have seen the v14 "what's new" but that is potentially only half the story. Any suggestions on how to piece together the full v12 => v14 "what's new" story?

I can tell you only what is important to me:

• the new support of Blackmagic hardware for the UHD preview (now up to UHD/4K)
• the support of ProRes. Not only that we had luminance issues with up to VP13, more: Vegas crashed with 25 ProRes Shogun files. I had to convert my Shogun files all the time to Cineform. That has now gone
• the HEVC encoder: with UHD we will see that HEVC will become the major delivery format. Not as 8bit as it is now, but with 10bit since that is the specification for new UHD televisions. So to include an HEVC encoder is the first step going into that direction
• a much better deinterlacing, since I have here also old AVCHD 1080 50i but also old HDV 1080 50i files

AND to me the most important major point, that the development of Vegas will be continued again!!

A lot of people seems to forget all the time that it was SCS who did stop the development. That is why we still suffer from poor GPU support for newer GPUs. That is why we still suffer from a slow 32bit floating point mode. This list goes on.

So to see that the development with Vegas Pro 14 will continue is important for the future, to avoid that Vegas becomes more and more outdated.

That is my opinion and that is why I think that Magix is doing a good job for this community. They ensure the future of Vegas.

I found another very minor problem with V14. If I open a project veg  then try to select another project from another hard drive from the file menu I cannot select another hardrive because it isn't shown in the menu. When I click a blank menu appears instead of showning new drives to select. If I close the file menu then open it up again all the hard drives appear and then I can select but after selection all the hard drives vanish and you have to close again to get them back. Yeah I know it's not a big deal.

If I open a project veg  then try to select another project from another hard drive from the file menu I cannot select another hardrive because it isn't shown in the menu.

Do you mean that you cannot navigate to another harddrive using the "Explorer"? Because that works here.

Also if I choose File/Open I can navigate to another harddrive.

What OS do you run? I run here win10 64bit and have no issue with that.
