I think that a solution should be found for the case, when an extension 
author simply does nothing and others users want to upload a modified 
version into TER which will work under the most current TYPO3 version.

This will lead to a situation where TYPO3 users will stay with e.g. 
TYPO3 4.5 for much longer than the 1 year until it is still supported. 
It would be better to enlarge the support time for TYPO3 4.5 by one or 
two more years than to allow the upload of an outdated but still 
maintained extension. This extension might run up to TYPO3 4.5 and is 
uploaded to TER in January 2016. This upload should be forbidden to that 
date. Otherwise it would be confusing and unsecure. And extension 
authors would continue their laziness to support the newer versions of

I propose to allow extensions which support versions until TYPO3 6.1 
also under TYPO3 6.2 alpha - 6.2 RC. This makes it easier for the 
testers to try out their websites under the first TYPO3 6.2 development 
versions. The Install Tool and Extension Manager should warn about 
outdated extension during the update to TYPO3 6.2. But it still should 
be allowed to ignore this warning and to use an outdated extension.
