Have they announced details for LTS plan for v4? This is probably most critical for us.
We are finding it hard to convince clients already bitten once by angular upgrade costs and now second time with ionic upgrade costs. That v3 stopped getting any fixes 9 months ago further hurt the sentiment, and puts a sense of unnecessary urgency behind upgrading to v4 - which isn’t ready yet.
LTS for v3 for 1 year after v4 release would have been best. Small things like upgrading v3 for Angular 6, 7, TypeScript vNext etc… would mean that clients can postpone v4 upgrade for a while longer. And we as an agency can schedule projects to upgrade them 1-by-1 at a steady pace instead of having to rush through it.
In absense of v3 LTS, v4 LTS should be at least 2 years after vNext is released.
