Given that:

• we won't make many more changes in LTS,
• the Piwik core team does not have available resource to work on these issues,
• there are too few contributions from other people and companies to solve these LTS issues,

-> we would like to remove the 2.16.x LTS milestone on Github.

List of 56 issues in 2.16.x LTS milestone

Currently this LTS milestone includes many issues that should ideally be fixed in Piwik: especially several small and medium bugs.

Here is the list of issues in this milestone as of today:
