It really depends on the TYPO3 version to what extend the version checks 
are done. In 7 LTS the checks are quite thorough: you won't see 
extensions in the "Get extensions" section of the Extension Manager that 
are not compatible with your release. If dependencies (TYPO3 version, 
PHP, other extensions) are not met you'll see a dialogue that it's not 
compatible and that you can install it if you know how to solve problems.

In earlier versions the checks were less strict or sometimes missing. 
This was mainly caused because those dependencies were only made 
mandatory for extensions in TER a few years ago.
For the recent TYPO3 version all compatible extensions have their 
dependencies set and we could finally have strict checks.

For older TYPO3 versions you can always search in TER on the typo3.org 
website (https://typo3.org/extensions/repository/ ) and read from the 
description if the version is compatible. The latest upload date may 
sometimes give you further information.
