Pan 0.14.90 is the first beta of a ground-up rewrite of Pan in C++.
Some of the best user-visible improvements:
* The memory footprint for large newsgroups has been cut by 2/3. (A month's
worth of headers in a sample binaries group dropped from 283M to 94M.)
* The time to download headers has been cut by 2/3 by parallelizing
the download across multiple conections to the server. (In the same
sample group, downloading a months' worth of headers dropped from
17 minutes to 5 minutes.)
* The time to load large newsgroups from disk has been cut by 90%.
(In the same sample newsgroup, the time to load from disk
dropped from 14 seconds to 1.3 seconds.)
* Multiserver support. Pan can now download files in parallel not just
with multiple connections to one server, but also to other servers.
* NZB support. Pan can now import NZB files. It can also be started in an
NZB client mode that doesn't create the newsreader window at all.
* All of the user interface windows and dialogs have been redesigned.
Some of the best backend improvements:
* The source code's line count has dropped from 44,382 to 23,093 --
and is far cleaner.
* Fewer library prerequisites: Pan no longer requires GNet or libxml2.
* Better decoupling.
_ Unit tests that were impossible before, such as tasks running and
talking to a mock news server, can now be done.
_ Pan can now run 'headless' to process queued tasks.
_ The task and application layers are separated from the backend,
so a database backend could be added in the future if desired.
