RSS Guard 4.0.1

RSS Guard

RSS Guard is a simple (yet powerful) feed reader. It is able to fetch the most known feed formats, including RSS/RDF and ATOM. It's free, it's open-source. RSS Guard currently supports Czech, Dutch, English, French, German, Italian. RSS Guard will never depend on other services - this includes online news aggregators like Feedly, The Old Reader and others.

RSS Guard is developed on top of the Qt library and it supports these operating systems:

Windows
GNU/Linux

xBSD (possibly)
Android (possibly)
other platforms supported by Qt

RSS Guard 4.0.0 release notes:

4.0.0 is new major release of RSS Guard. RSS Guard 4.x is NOT backwards compatible with 3.x line.

Specifically:

configuration file "config.ini" IS fully backwards compatible,
database file "database.db" is NOT backwards compatible.
You may ask why is there new major version and why backwards compatibility is broken:
I needed to completely overhaul some of core concepts inside RSS Guard.
Database structure in file "database.db" was very complicated and hard to maintain and had to be simplified. Number of database tables was greatly reduced and whole structure is easier to follow.
Source code was greatly simplified in many places which makes RSS Guard easier to maintain and easier to develop new features.
Also, and this is potential killer feature, new changes allowed implementation of "next-gen" synchronization algorithms which may, in some cases, dramatically speed-up two-way synchronization of articles. This new synchronization algorithm is right now implemented and enabled for Google Reader API plugin as PoC and it is called "Intelligent synchronization algorithm" within RSS Guard. The algorithm will be implemented for other plugins over time.
There is crazy number of new features and bugfixes. See list below.

Also, let me say some more extra points:

More than 4 000 code changes were made in total during RSS Guard development. Codebase consists of 38 500 lines of C++ code.
First version of RSS Guard was published 8 years ago.
RSS Guard is one-man project, I have implemented it on my own. 99% of code is written from scratch.
Received donations for RSS Guard were under 100 USD in total.
If you feel that RSS Guard is slow, broken or shitty application, then you are probably right. Nonetheless, you should still submit well-structured and sane bug report, so that I can actually fix the issue! If you do not submit bug report, then please do no spread lies about how bad RSS Guard is and switch to another feed reader instead.

Added:

Brand new notifications subsystem added. It can play sounds, individual events are independently configurable in application settings. (#356, #144)
"MessageObject" class now exposes "rawContents" property for message filtering. Property contains raw RSS/ATOM/JSON contents of the message. (#377)
URL-embedded cookies are now supported, as well as classic cookies, which are now saved in non-persistent cookie jar. (#391)
"Next-gen" synchronization algorithms which may, in some cases, dramatically speed-up two-way synchronization of articles. This new synchronization algorithm is right now implemented and enabled for Google Reader API plugin as PoC and is called "Intelligent synchronization algorithm" within RSS Guard. The algorithm will be also implemented for other plugins in the future.
Google Reader API plugin supports "ot" option.
Documentation was completely rewritten.
Fixed support for OS/2.
Optional notification for login failures.
Improved bug report templates (PR by sakkamade). (#467)

Visual state of some dialogs is now remembered, for example "Cleanup database".
Some GUI texts and terms were unified and changed (message -> article, download feed -> fetch feed, etc.). (#430)
There is now some default filename set when exporting feeds to file.
Number of unread messages is now shown on Linux also in taskbar (not just tray icon). (#437)
