--- Comment #1 from Ondřej Kuzník ondra@mistotebe.net --- Hi Emmanuel, given we're now finalising the 2.5.20/2.6.10 releases, the plan is for 2.5.20 to be the last regular release for 2.5's LTS stream and 2.6.10 the last release when 2.6 is considered a feature stream.
After that, what was trailed in that email would take effect, 2.6 would be marked as LTS on the website, noting that 2.7 would become the next feature stream when it's released later this year.
Hope that clears things up a little.
