Ubuntu LTS 10.4 vs upgrading to newer versions

[SULO]

Hi, currently my laptops is running 10.10

I haven't been having any problems so far nor I felt any improvement (functionality wise) over 10.4 .
But today I came across a small problem:
I went to Cilenerra's website - a Powerful video editing software. I saw that they have a version for 10.4 but not for 10.10 yet. Now I'm unable to get that software.

1. My question is, will I be encountering this type incompatibility issues in the future if I keep getting the latest Ubuntu distros?

2. What if I choose to install 10.4 LTS and stick with it long term? Will I start getting incompatibility issues after a year or so?

3. Will the 10.4 get more and more stable and responsive with newer updates until the new LTS?

EDIT:
and if you're wondering, I tried installing the repository of Cinelerra, but the Ubuntu Software Centre kept telling me that there's no version available for my OS.

1. Probably. It takes some time for certain software to catch up with a new release sometimes.

2. No. I ran 8.04 LTS for years before upgrading to 10.04 LTS and had no incompatibility issues you speak of.

3. !0.04 LTS. By it's very nature. Will stay stable (as far as Ubuntus go).

Thing is. Do you want cutting edge or stable? Cutting edge comes with it's own quirks. Stable also comes with it's own set of quirks.

I run unstable testing sid repos in AntiX 8.5. But I also run 10.04 LTS stock stable repos in my Ubuntu Desktop and Acer Netbook.

Up to the user as usual.

Edit: about Cinerella. Since you sound new to Ubuntu and seem unfamiliar about installing from source. I'd leave well enough alone for right now. Just dealt with a another user who thought tinkering with a working install was a good idea.Up to you though.
