[gscan2pdf-help] scantpaper v3.0.6 released

[Ted S. <te...@ra...>]

it seems like the most recent issues with scantpaper are related to 
versions of dependencies.  Would it make sense to issue flatpaks which 
have the proper version libraries used  included? That will eliminate 
many problems.

I have attempted to install scantpaper v. 3.0.6 on CachyOS, an archlinux 
derivative.

Unlike my previous attempt, I was able to install tesserocr, after which 
scantpaper moved on to another missing dependency: goocanvas2.  After 
this ( downgrade from the installed goocanvas 3 version), 
scantpaper tried again.  The next message is beyond my understanding.  
Perhaps it will be of some interest?

Ubuntu is not a rolling release distro, so one kind of expects these 
failures to use up to date dependencies. Probably, eventually things 
will settle down.  This is an improvement, I think.  CachyOS keeps up 
with upstream, as far as I can tell.

    I tried to release scantpaper v3.0.6 at the weekend. It was impossible
    to upload to the PPA until today; it seems because Launchpad was the
    victim of a DDOS.

    Changes compared to v3.0.5

    * Improve error messages when helper tools not found
    * Fix bugs adding and removing paper sizes
    * More improvements to UI responsiveness showing hidden text layer
    * Fix race condition causing occasional hang at startup
