This new release contains big improvements in term of performance.
MWoffliner 1.8 does not require anymore zimwriterfs binary and can write
directly on-the-fly offline ZIM files. This means far less mass storage
usage and a number of IO accesses divided by around 5.
All of this has been made possible because a new software piece in
binding of our ZIM format reference library: libzim. It allows quickly
our code forge at https://github.com/openzim/node-libzim and of course
available at npmjs.org: https://www.npmjs.com/package/@openzim/libzim.
This is the third milestone of a few we have planned with the support
of the WMF. Next one on the list is 1.9 and is planned for end of April.
With 1.9 we want to implement the full support of MediaWiki categories.
