This year, hopefully summer time.

Almost/well/almost/well. 

There are a couple more features I want to add and optimise some will probably 
wait till 1.6. In terms of finishing off, a lot of code is using old 
implementations and needs to be ported over to improved methods. This is easy 
but tedious. 

1.5.x is generally much more robust that 1.4.x. The ‘unstable’ in these 
releases refers to the fact that APIs might change between minor versions and 
not that the code is buggy. Although some issues do pop up in production of 
course there are far fewer test failures. CDK-KNIME has been using 1.5.x for a 
long time, Ambit was recently migrating. I’ve been using it since 1.5.1 as 1.4 
really didn’t do what I needed. 

Remaining test fails are mostly to do with MM2 and MMFF94 forcefields. This 
would be a lot of effort to fix (and I might do it) but it is possible those 
entire modules (forcefield/builder3d) could be deprecated. It would be useful 
to know if anyone on list is using these.

Egon has been documenting some change - 
http://chem-bla-ics.blogspot.co.uk/2014/05/changes-in-cdk-16-5-smiles-generator.html.

I think the biggest change that causes the most pain in upgrading is the 
removal of Molecule.
