I wouldn´t be so pessimistic! It brings much the community has asked for! Visual Studio 2017 support, Schematyc improvements, aand they teased substance designer intergration (what many people demanded), a multiplayer template, which makes it easier creating multiplayer games etc. So I think it´s also a good step and as long as CE 5.5 isn´t affected by the release it´s OK.After months and months of nothing... imagine 5.4 will bring just a view small tools and a little bit of stability to the engine... This small community will become in one blow even smaller.
Lets hope 5.4 will be mind blowing and stable/unbreakable like a diamond.
