I just upgraded and now the slideshow does not work in album work/diashow. I see the Codeblock is depricated, but I can't find the new syntax for making an album go slideshow.
Found macro [SLIDESHOW........] but no good example on how to get my album 'work/diashow' working...
Please help

Codeblocks itself are not deprecated, you just need to make sure your theme uses the one you set. Since you didn't tell which theme you use you will have to take a look yourself.

The macros are explained here:

And for the two slideshow plugins (both work the same way) here:

Sorry, I use 1.4.4.8 with zpFocus and in album work/diashow i put [SLIDESHOW work/diashow true 1600 1600] in a new codeblock.
