The next
step is to remove support for zlib and bzip2.
Currently I'm working on porting the new file format to the nano note.
Unfortunately I'm stuck with porting xz (the lzma-library) to openwrt.
There are some difficulties there, but I'm sure, they can be resolved. I
have already asked for help at the openwrt developer list but have not
yet received any answers.
That's why I asked to be careful by removing bzip2
and/or zlib.
It's essential to have at least at any moment a working solution for
every arch/system. I have for example not checked if xz works good with
Windows.

We want to define a standard format. And if you create zim files with lzma
compression we need to make sure, we can read the file on every system, we
support. It makes no sense to have some zim files with bzip2 compression, which
work on windows and other zim files with lzma compresion which don't. We have
to commit us to one compression method to prevent fragmentation. Or do you
want to offer zim files for ubuntu and zim files for windows and zim files for
fedora and zim files for freebsd?
I prefer having *now* a solution with 3 compression algorithms and
knowing one of them does not always work than having a format which is
totally unusable in a few use cases.
So, we will try to have lzma working everywhere... but as long as this
is not sure, it would be preferable IMO to be able to say "look you can
use bzip2" than "sorry zimlib is not for you, it does not work currently
for your use case".
We have to choice our disadvantage:
* Remove bzip2 and having the risk to discover portability issues
* Keeping the bzip2/gzip dependence a little bit longer
... in any case this is not so critical... in the worth case we will
have to work hard to fix the portability issues... and I hope we will
because we want the zimlib being portable.
