Hi,

I just checked [Compatibility Matrix](https://www.elastic.co/support/matrix) today and I discovered that **all Logstash and Elasticsearch 1.x versions references have been removed**.  
We still use those versions (I know that's bad) and sadly I did not save it.  
We need the full (previous) matrix in order to define a correct migration path through compatible versions.  
Where can I find such information now ?

Thanks  
Tom
