Before you start to panic, this does not mean we are no longer building Pi1 images. We will continue to provide Pi1 images as long as there is a Pi2 build.
This only means we will no longer test Pi1 images ourselves. Pi1 images will still contain all the fixes that Pi2 images will contain in the hopes that they will just work (most application-level fixes should just work anyway), but we won’t necessarily flash a Pi1 and test them before release. We will also continue to try and address issues that you report as long as they are easily fixable.
The decision to phase out direct support for Pi1 has come about due to lack of Pi1 feedback we see in the forums as well as the lack of developer time necessary to test everything, and also the fact that Pi1 is a bit underpowered for our software and not longer a worthwhile target (in terms of experience of using it / development cost ratio).
As a Pi1 user, your options are:
a) Research the problem you are having and make it easier for us to fix them (really try to figure out what the cause is rather than simply sending us the logs)
b) Fix them yoruself and submit a pull request on GitHub so the fix can be integrated
c) Use Pi2 instead (if you have or can get one)
