Where should I _append Yocto bitbake task to create work folder symlink?

Let’s say I have my package at

host-64/tmp/work/x86_64-poky-linux/mypackage/1.2.3-r4/

JavaScript
​x
 
host-64/tmp/work/x86_64-poky-linux/mypackage/1.2.3-r4/​

I would like to have symlink created

host-64/tmp/work/x86_64-poky-linux/mypackage/latest -> 1.2.3-r4/

JavaScript
 
host-64/tmp/work/x86_64-poky-linux/mypackage/latest -> 1.2.3-r4/​

each time the new version is fetched and unpacked. How can I achieve that ? Which class, task should I append, extend ?

Optionally, I would like to have that for all packages or at least packages in my meta.

Answer

A new task that comes after unpack will probably be a suitable place to add the link.
