4.7.0
-----

OK, dear users. Over recent releases, many features were added and as you can see RSS Guard bug tracker is full of (semi) bug reports which need to be addressed. Therefore I must declare feature-freeze for at least three upcoming releases. No new features will be added in forthcoming future, because RSS Guard codebase must be de-bugged and stabilized first. I will keep my word this time and no feature requests will be implemented.

Sole focus will be on fixing bugs and polish existing features and clean codebase.

Added:
* Full article content can now be fetched with a single button. Button is placed in article viewer toolbar right next to "Reader mode" button. This feature (just as "reader mode" feature) requires Node.js installation. The feature works both for articles and for regular websites opened in embedded web browser.
* Article now can be marked (upon selection) as read with delay or only manually. (#1017)
* All RSS Guard plugins/services are now placed in their own library (DLL/SO/DYLIB) files and are loaded by main RSS Guard library dynamically. This means that unused services can now be removed from RSS Guard installation if not used by the user. Also it allows for a cleaner and slimmer common codebase. Refactoring of main RSS Guard library was also done and it is now more usable as regular dynamic-link library. I expect some regressions as this was HUGE change. Also, this change allows new potential interested people in writing new plugins easier as they now can just copy one of existing plugins and tweak for new service. Also this change now propagates to RSS Guard installer which allows you to only install plugins/services you want.
* Application (Qt) style and icon theme now can be properly set to respect system style/icons and this setting is dynamic, meaning if you change system theme and restart RSS Guard, new theme is honored. (#1352)
* Button to copy system/app information to "About..." dialog. (#1318)
* All modal dialogs now remember their sizes forever. (#1336)

Fixed:
* Removed debugging forgotten code. (#1354)
* "Cleanup" button in downloader was greyed out when it should not be. (#1350)
* App crashes when changing notification sound. (#1317)
* Built-in user-agent was updated. You can also supply your own user-agent, see `rssguard.exe --help` for more info.

4.6.6
-----

Fixed:
* Some build problems and regressions are now fixed, sorry for this.

4.6.4
-----

One bigger new thing, dear users: I decided to start implementing brand new purely command line only version of RSS Guard to allow running RSS Guard in headless/CLI environments like servers. It will likely work like this:
1. You run regular variant of RSS Guard and setup your feeds, how often they fetch like you normally do when running classic GUI RSS Guard.
2. You then can launch new CLI-only RSS Guard executable perhaps on your server (or elsewhere) and it will load your settings/database and will perform article fetching regularly.

Added:
* Existing read/unread state is respected when some article gets "updated" (infamously happens for YouTube feeds). (#1279)
* NSIS installer was bit tweaked to warn about MSVC runtime. (#1306)
* iCalendar files (*.ics, *.ical) are now supported. Note that the support is rather basic.
* Added more ways of limitting amount of articles in each feed. (#1270, #1267)
* Added way to use old legacy article formatting in "lite" version. (#1286)
* New way of fetching articles - new "Source" -> "Built-in web browser with JavaScript support" which allows user to use built-in Chromium-based network stack to fetch feeds and other data. It allows even fetching of majority of JavaScript-powered websites. (#1313)
* More date/time strings for parsing some dates and times in articles.
* "Title" column in article list is not directly resizable too. Last visible column auto-stretches to fit remaining space. (#1319)

Fixed:
* Fix freezing when feed uses crazy crazy loooong URL.
* Fix crash when forwarding e-mail via Gmail plugin.
* Add forgotten restriction when cleaning data. (a975714f6)
* ETag conditional loading of feeds was semi-broken. (#1314, #1296)
* All Unicode characters in feed URLs are now supported. (#1310)
* Reader mode was changing content for all opened browser tabs. (#1300)
* Some articles were displayed with broken HTML. (#1293)
* Size/position of all windows (including modal dialogs) is now guarded to not be out-of-screen-bounds. (#1281)
* No more crashes when adding some discovered feeds. (#1280)
* Main window pesky splitters saved with 0 position. (#1271)

4.6.3
-----

Dear users, there are new features which will be introduced in one of coming releases.

First of them is built-in HTTP API server which will provide basic REST-like interface for working with RSS Guard - getting list of articles, marking articles read or unread, etc. This will allow to use RSS Guard as a article server in local network.

In cooperation with the above feature, new "magazine view" will be implemented. This magazine view will be launchable even completely separately from RSS Guard in web browser and will be able to act as very simple web-based feed/article reader. It will fetch data directly from RSS Guard via its new web API and will display articles including their thumbnails in cool way. This feature will be also expanded in the future, based on user feedback.

Added:
* Lite internal web browser now properly decodes all HTML pages according to their declared encoding. (9c7f55094)
* Image downscaling in lite browser is faster. (8b91d4709)
* Icon for classic RSS/ATOM accounts is now changeable. (#695)
* If main window is active then "fetching started" notifications are not delivered. (#597)
* Number of child feed/categories is now shown for each category. (#1183)

Fixed:
* MPV libs were moved to separate Git submodule. (#1250)
* Applied workaround to fix PC not sleeping after sound is played. (#1118)
* Fixed problem with disappearing tabs.

4.6.2
-----

This release fixes couple of issues found after 4.6.0/4.6.1 releases.

Fixed:
* Fixed "Browse" button not working in "Media player" tab of settings dialog. (#1245)
* Was crashing on Linux. (#1244)

4.6.1
-----

Fixed:
* Fixed some compilation problems and related issues.

4.6.0
-----

This feature brings one major feature - podcast/media player. This media player is available when you open context menu for any hyperlink in article which you think leads to audio/video file. Simply right-mouse-click your link and select "Play in media player", then media player will open in next tab and start playing.

Full versions of RSS Guard (with QtWebEngine) include libmpv-based media player which can play basically every thinkable audio/video content. Windows build of RSS Guard even bundles yt-dlp binary to allow out-of-box support for Youtube playback.

Lite variants of RSS Guard include slightly lighter QtMultimedia/ffmpeg-based media player, which also can play many audio/video formats.

Qt5-based lite variants of RSS Guard will likely require you to install some system-wide codec pack.

https://github.com/martinrotter/rssguard/issues/1226

Added:
* Media/podcast player capabilities. See above for more information.
* Indication of which feed is actually fetching at the moment can be enabled in settings. (#1203)
* Newspaper view was removed as it was slow and very buggy. It might be replaced by something better in the future.
* Sections of settings now have icons.
* Docs updated.
* Layout of articles in default nudus-* skins was unified for full/lite versions. Formatting is now very similar.
* Image size/wrapping behavior was greatly improved in article viewer, particularly in lite version.

Fixed:
* Context menus in both full/lite article viewer are now more similar.
* Fixed crashing when editing e-mail via Gmail plugin. (76c7dd170)
* No more warning journal messages generated on Linux. (#1207)
* Updated and fixed some languages. (#1205)

4.5.5
-----

Added:
* Added feed manipulation for Google Reader API plugin - creating, editing, deleting feeds.

Fixed:
* Fixed yellow background in nowebengine version.
* No more double right mouse button click when closing notifications.

4.5.4
-----

Added:
* Toast notifications now have configurable width, margins and opacity. Couple of related GUI fixes are also there. (#1125)
* Standard RSS/ATOM account now can be renamed. (#824)
* Aux nodes "Important", "Probes", "Unread" and "Labels" now can be disabled per-account separately in account settings dialog. (#584)
* Toast notifications can be closed with right mouse button click.
* Google Reader API plugin now offers OPML import and export function. See context menu for it.

Fixed:
* Updated translations.
* Fixed integration with Miniflux via Google Reader API plugin. This requires additional testing. (#837)

4.5.3
-----

Added:
* Article and feed toolbar heights are now normalized to same values.

Fixed:
* Fixed couple of cases where feed multi-selection and/or batch operations were not taking multi-selection properly into account.
* Fixed some unnecessary prompts to restart app in settings dialog.
* Updated translations and readme.

4.5.2
-----

Dear users. Note that one of upcoming releases will break-backwards compatibility thus it will be labelled as "5.0.0". Backwards compatibility will be broken in several areas of the application - particularly I want to greatly enhance syntax/API of article filtering scripts, where I plan to restructure existing functions, make it all bit more clear and add some more functions.

Also, some other areas of RSS Guard might be touched so I will use the opportunity to make again some enhancements. I do not expect that DB incompatibility will be as high as it was when transitioning from 3.x to 4.x and I expect that existing RSS Guard databases will be converted to "5.x" format automatically.

Moreover, I thank to all users of this app. Currently according to my internal "guess" I believe that RSS Guard has 5000+ regular users and it is likely one of the most used RSS desktop cross-platform applications. I hope we will grow and I also send big thanks to all who donated some money. It is not much, but I have used some of it to buy parts for my home PC on which I develop RSS guard mostly. Thanks.

Btw, just thinking out loud. If each user contributed 5 USD per year, I could do RSS Guard development as my full-time job, which I would love to. :D

That's all I wanted to say. Thanks, users.

Added:
* Added new "Discover feeds" dialog which is automatically opened when user hits "Add new feed" button. In this dialog, use does not have to input exact feed address but can enter just regular website address and RSS Guard will try to discover all available feeds possible. (#1134)
* ATOM/RSS/JSON/Sitemap feeds now automatically use "ETag" HTTP headers which has potential speedup when fetching feeds with no new messages. This can bring 10-80 % speedup if user uses more feeds which do support "ETag". (#1136)
* Support for Sitemap "sitemap.xml" files is added! Vast majority of websites have sitemaps and RSS Guard now can read them in the same way it does with RSS/ATOM formats. "Discover feeds" dialog has Sitemaps support integrated and it even is able to traverse sitemap indexes. GZipped sitemaps are supported too. (#1129)
* Added multiple/extended selection to feeds list! Now it is possible to select multiple items at once (feeds, categories, etc.) and perform batch actions on them - batch editing, deleting, marking read/unread, re-sorting - when some feeds are selected it is now in "Edit selected items" dialog possible to batch change only some properties in a very clean and universal way. (#1010, #89)
* Localizations updated.
* Documentation updated.
* Arguments parsing is now totally overhauled. It is now possible to use both double and single quotes to quote arguments. Read "Scraping Websites" chapter in [docs](https://rssguard.readthedocs.io/en/latest/features/scraping.html#scraping-websites) to know more.
* Local files can now be used directly as sources for feeds, just select "Local file" in add/edit feed dialog.

Fixed:
* Fixed OPML import/export when some feeds use custom script as source. (#1133)
* RSS/ATOM parsing is now greatly enhanced.

4.5.1
-----

!!! [Documentation](https://rssguard.readthedocs.io) was migrated to ReadTheDocs platfotm and some parts of it were updated !!!

Added:
* Completely new, custom "toast" notifications:
    * Configurable position on screen.
    * Can be displayed on secondary screens.
    * Automatically adopts look of currently active RSS Guard skin.
    * Can be close via close corner button or via `Esc` keyboard button.
    * When hovered with mouse, notification stays shown, when not hovered, it is automatically hidden after 15 seconds.
    * Displays list of newly fetched articles and offers some basic actions like marking as read, showing in article list or in web browser.
    * These notifications do not need "tray icon" to be activated.
    * Can be tweaked in `Notifications` section of settings.
* `pdb` debugging file is now distributed with RSS Guard on Windows.

* Fixed behavior of Google-based phrase suggestion in web browser navigation text box.
* Many different features of RSS Guard got minor fixes, some parts of source code were refactored. Particularly, one nasty "semi-bug" was fixed which influenced speed of article switching in article list. It should now be faster. Much faster.
* Article counting for "regex queries" is now disabled because this was very performance-hungry even with small number of regex queries, sadly.
* Translations of some languages are now more complete.
* Some unused source code was removed.
* Some unused deps were removed.

4.5.0
-----

Localizations are now translated via Crowdin: https://crowdin.com/project/rssguard

Added:
* List of article filters assigned to feed is now visible in feed details pane. (#1045)
* Right-to-left optional layout for feeds/articles. You can switch this in each feed properties.

* macOS build is now built with macOS 11.
* Linux build is now built with Ubuntu 20.04 which is now oldest supported Linux LTS distribution.
* Reworked logic of determining which article states (read/unread/starred/unstarred) have changed when synchronizing states to remote feed servers. This concerns all synchronized plugins like Gmail, Greader, Feedly, etc. and show in theory lead to much better performance when you mark many articles as read or unread.
* Couple of extra QoL enhancements for Gmail like proper encoding of attachment filenames, turned off displaying of "enclosures" as these are displayed in other way, etc.

Fixed:

* Added option to focus feed/article lists with keyboard shortcuts. (545)
* Uninstaller now should detect if RSS Guard is running or not. (#529)
* Gmail: Original e-mail body is now appended to response.
* Gmail: E-mail preview now uses styling from skin for unified UX.
* Minor enhancements for OPML importing.

Fixed:
* Showing pictures from authenticated feeds now should work. (#909)

* Some memory leaks were patched and also SQLite database connections now share "cache" across all threads, resulting in drastically better RAM usage of the app.
* Feedly: Article state synchronization now works.
* Updated docs, updated translations.

4.3.2
-----

Added:
* Display total number of underlying feeds/categories in account's tooltip in feed list. (#881)
* Press "CTRL+F" when article script textbox is highlighted in "Article filters" dialog to allow for text searching. (#889)
* Filtering option in article list toolbar are now inclusive with checkbox like appearance. You can now thus select multiple filtering conditions and if article meets atleast one of them, it is displayed. (#468)

* Fixed TT-RSS icons downloading when obtaining list of feeds/folders.
* RSS Guard now converts all placeholders (for example "%data%") to native path folder separators.

4.3.0
-----

Added:
* Massive update for feed fetching mechanism. It is now very parallelized and performance gain should be brutal. On my development PC with 4 cores (Intel i5) I observed 800 % performance boost. Note that this feature required huge number of changes on source code so there could be some corner case regressions or not so polished situations. File bug report when that happens. Also, number of threads used by this feature is configurable via `--threads` command line switch. This parallelization approach will also be applied to some other parts of application in the future, particularly for some massive batched network operations in some plugin - TT-RSS, Greader or Gmail - which will result in massive performance boost too.
* RSS Guard is now available on Flathub in two distinct variants - "full" and "lite" (same as "nonwebengine").
* Suffix ".xml" is also accepted for OPML 2.0 files.
* Brutal speed enhancements when importing OPML 2.0 files. Whole functionality is now properly parallelized and performance boost is potentially massive, depending on number of your CPU cores/threads.
* Qt 6 bumped to 6.4.2 version - this fixes some regressions.

Fixed:
* Some random Mac OS X crash. (#866)

4.2.7
-----

Added:
* Released only due to technical reasons. (#836)

* Added application debug log dialog. See "Help" menu for more.
* Too big fetched feed icons are now automatically scaled down to fixed size (48x48).
* Now it is possible to run post-process script when importing OPML. (#848)
* Now it is possible to change "User-Agent" HTTP header. (#835)
* Added now column into article list which shows labels for each article. (#768)
* Now it is possible to "suppress" feed. Suppressed feeds do not trigger notifications. (#745)

* Avoid appending empty RSS enclosures to articles. (#832)
* AppImage reverted to Qt 5 as Qt 6 support in AppImage generator is very very buggy.
* All dialogs where icons/images are selected now load their "formats" dynamically to support all possible image formats correctly. (#834) This effectivelly adds "webp" and other formats on systems where it is supported.
* Fixed crash. (#849)
* Enable smooth-scrolling by default. (#793)

4.2.5
-----

Added:
* RSS Guard now can use super fast feed/article refresh rates. At this point it is possible to set refresh interval even to 1 second to allow super fast checking for content changes. (#723)

Fixed:
* Newspaper mode caused some GUI glitches. (#810)
* Feedly crashed whole application when performing folder/feed synchronization. (#807)
* Some specific feeds are faulty but some adjustments were made to make RSS/ATOM parsing more loose. (#805)
* Fixed HTML/plain article content auto-detection for some specific HTML cases. (#792)
* Lessened severity of some debug messages. (#804)

4.2.4
-----

Added:
* Intelligent and network-usage-friendly two-way article synchronization is now supported in TT-RSS plugin too. Note that "api_newsplus" plugin must be installed on your TT-RSS instance. (#339)

* Google Reader API plugin now supports Miniflux. (#780)
* Full-blown drag/drop feed/category reordering/sorting. Behavior is different depending on whether "alphabetic sorting" is enabled or not. (f63af3a05)
* Windows and Linux official packages now use Qt 6.3.1 or newer. Qt 5.15 is still supported, though.

Fixed:
* Handling of CLI parameters was improved in several places throughout the app. This fixes calling external browsers etc. (#748)

* Added a switch to automatically reject all incoming HTTP cookies application-wide. (#716)
* Gmail: Display proper "To" e-mail header when displaying e-mails.

Fixed:
* Feedly: Correct article URLs are now fetched if possible. (#732)
* Mac OS X: Fixed launching with error "invalid application". (#721)

* Feedly now decodes feed titles from HTML to plain text.
* New CLI "-w" option to force "nowebengine" behavior even in standard "webengine" RSS Guard builds.
* Article viewers are greatly refactored and internally use sane C++ interface - this allows this piece of RSS Guard to be expanded better in the future.
* "nowebengine" text-based article viewer now can display images. (#583)

4.2.1
-----

Added:
* Number format of unread counts in task bar icon and tray icon is now enhanced. It shows format "%1k" for number bigger than 999, for example 16 000 of unread articles will be displayed as "16k". (#662)

Fixed:
* Dynamic libraries are now properly "linked" in Mac OS X build. (#663)

4.2.0
-----

Added:
* Items in feed list (accounts, categories, feeds) now can be manually sorted. Go to "Feeds -> Sort alphabetically" menu option to switch the feature. Then you can re-adjust sort order with context menu on each item. (#302)

* Individual feeds can now be turned off. Turning feed "off" disables it and it won't get any new articles. See "Edit feed" dialog, specifically "Miscellaneous" tab. (#393)
* Gmail: Synchronization of e-mails is now MUCH faster, especially subsequent synchronizations. Also, some Gmail-related fixes were added.
* TT-RSS: Added "share to published" feature which allows user to save custom notes to TT-RSS. Can be used with context menu on "[SYSTEM] User-published articles" feed list item. (#198)
* Count of unread articles in taskbar is now switchable. (#649)

4.0.0
-----

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.

* Google Reader API plugin is greatly enhanced, has better support for TheOldReader.
* Inoreader plugin was merged into Google Reader API plugin as Inoreader too uses Google Reader API.
* Toolbar search boxes have now dynamic width. (#431)
* 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)
* Unified minimize/maximize/close window buttons in all RSS Guard dialogs. (#439)
* Most of text boxes now have "clear text" button. (#438)
