+  - please see repository change log at
+    https://github.com/nzbget/nzbget/commits/develop
+
+nzbget-21.1:
+  - fixed crash on systems with 64-bit time;
+  - corrected icon in Windows "uninstall program" list;
+  - allow special characters in URL for username and password;
+  - improved reporting for binding errors on Windows;
+  - fixed unicode space characters in javascript files, which could cause issues
+    with nginx proxy;
+  - fixed negative values for "FileSizeLo" in json-rpc;
+  - corrected url detection in rpc-method "append";
+  - added support for new error messages in unrar 5.80;
+  - now always using snapshots when reading directory contents:
+    - in previous versions snapshots were used on macOS only;
+    - now they are used on all OSes;
+    - this solves issue with leftovers during directory cleanup, which could
+      happen on certain OSes when working with network drives;
+  - fixed file allocating on file systems where sparse files are not supported:
+    - the issue could happen when InterDir was located on a network drive;
+  - fixed crash caused by malformed nzb files;
+  - fixed GROUP command in nserv;
+  - updated url of the global certificate storage file in the build scripts;
+  - fixed: file selector in WebKit based browsers doesn't allow to choose the
+    same file again;
+  - removed outdated links from web interface;
+  - fixed PC sleep mode not working (Windows only);
+  - set "SameSite" attribute for cookies;
+  - corrected typo in about dialog of web interface;
+  - updated license text: changed address of Free Software Foundation and minor
+    formatting changes.
+
+nzbget-21.0:
+  - reworked duplicate handling to support URLs, especially when using RSS
+    feeds:
+      - queue items added via URLs (to be fetched by nzbget) are no longer
+        immediately fetched;
+      - instead url-items are handled by duplicate check similar to nzb-items
+        and may be placed into history as duplicate backups;
+      - if an url-item needs to be downloaded as backup for a failed other item
+        the nzb-file is fetched via provided URL;
+      - this greatly reduces the number of nzbs fetched from indexers when using
+        RSS feeds and duplicate handling;
+  - improved support for Android devices:
+    - now providing a separate installer package for Android;
+    - the package contains binaries built using Android NDK;
+    - this improves compatibility with Android, in particular with Android 8,
+      where general Linux installer version of NZBGet didn't work anymore due
+      to security changes in Android;
+    - android installer app is updated to use the new android installer package
+      instead of general Linux package;
+  - thoroughly optimised the program to reduce power consumption in idle state:
+    - number of CPU wake ups in idle state has been reduced from hundreds times
+      per second to about only one per second;
+  - optimisations for large queues with thousands of items:
+    - speed up saving of queue state and reduced number of queue state savings;
+    - improved queue state format to reduce amount of state data saved during
+      downloading;
+    - in tests download speed for very large queue (16000 items) has been
+      increased from 45 MB/s to 300 MB/s (comparing to 400 MB/s with small
+      queue); 
+  - added native support for aarch64 architecture (ARM 64 Bit CPU) in Linux and
+    Android installers;
+  - force par-check for nzbs without archives;
+  - added functional tests for unpack CRC error;
+  - click on nzbget logo in web-interface now switches to downloads tab instead
+    of showing "About dialog" which has been moved into settings;
+  - improved handling of files splitted via par2;
+  - added python 3 compatibility to EMail.py script;
+  - added python 3 compatibility to Logger.py script;
+  - proper UTF-8 encoding of email content in EMail.py script;
+  - improved error reporting for queue disk state corruption;
+  - updated unrar to 5.7 and 7-zip to 19.0;
+  - Windows installer now includes unrar in 32 bit and 64 bit variants;
+  - allowing wildcards in option AuthorizedIP;
+  - removed suggestion of RC4 cipher;
+  - better description of option UMask;
+  - integrated LGTM code analyser tool into project;
+  - fixed: failed downloads not having any par2- or archive- files were moved to
+    DestDir instead of remaining in InterDir;
+  - fixed crash when using FIPS version of OpenSSL;
+  - fixed compatibility issue with OpenSSL compiled without compression support;
+  - fixed deprecated OpenSSL calls;
+  - fixed potential crash in built-in web-server;
+  - fixed: statistics for session download time and speed may be way off on high
+    load;
+  - fixed many compilation warnings in GCC;
+  - fixed: macOS menubar widget could not connect if password contained special
+    characters;
+  - fixed: remote clients not displaying current download speed;
+  - fixed: remote server could crash when feed with invalid api request;
+  - fixed trimming of relative paths in config.
+
+nzbget-20.0:
+  - massive performance optimisations in downloader:
+        - improved yEnc decoder;
+        - improved CRC32 calculation;
+        - processing data in one pass;
+        - SIMD implementation of decoder and CRC functions on x86 and ARM CPUs;
+          SIMD code relies on node-yencode library by Anime Tosho
+          (https://github.com/animetosho/node-yencode);
+        - overall performance improvement up to +500% on x86 and +250% on ARM
+          (better speed or less CPU usage);
+  - using glibc instead of uClibc in universal installer builds for Linux:
+        - this significantly improves performance;
+        - compatibility with Android and other systems is hopefully also improved;
+        - in universal installer glibc is used on x86 and ARM;
+        - uClibc is still used on MIPS and PPC;
+  - performance optimisations in web-interface:
+        - reduced number of requests when loading webui by combining all
+          javascript-files into one and all css-files into one;
+        - reduced load time by calling multiple API-methods simultaneously;
+        - extensive use of browser caching for static files significantly
+          reduces the amount of data transferred on webui initialisation;
+        - extensive use of browser caching for API requests reduces the amount
+          of data transferred during webui status updates, especially when
+          nzbget is in idle state and there are no changes in download queue or
+          history;
+        - avoid work in browser on status updates if there are no changes in
+          download queue or history;
+        - support for keep alive connections significantly reduces overhead for
+          establishing connections on webui status updates, especially when
+          connecting to nzbget via TLS/SSL (avoiding TLS handshakes);
+  - a number of performance optimisations for large download queue with
+    thousands of items:
+        - much faster loading of queue from disk greatly improves program start
+          up time;
+        - improved queue management for faster download speed;
+  - now offering 64 bit binaries for Windows:
+        - installer includes 32 and 64 bit nzbget binaries;
+        - when updating from older versions the 64 bit binary is installed
+          automatically, although into the old location to keep all your
+          shortcuts intact;
+        - using word "windows" instead of "win32" in the setup file name;
+  - automatic update check:
+        - new option "UpdateCheck" to check for stable or testing versions (or
+          disable);
+        - when a new version is found a notification is shown;
+        - the update check is enabled by default for stable versions;
+  - significantly improved logging performance, especially in debug builds;
+  - par-check prints par2 creator application to help identify creator app
+    issues;
+  - added support for Unix domain sockets (POSIX only);
+  - better error handling when fetching rss feeds;
+  - updated POSIX build files to newer autotools version:
+        - compatibility with newer autotools;
+        - compatibility with newer platforms such as aarch64;
+  - better username/password validation when testing connection on settings
+    page;
+  - improved rar-renamer to better handle certain cases;
+  - new option "SkipWrite" for easier speed tests;
+  - support for redirect codes 303, 307 and 308 in web-client for fetching of
+    rss feeds and nzb-files;
+  - installer for FreeBSD is now built using Clang instead of GCC; this fixes
+    incompatibility with FreeBSD 11;
+  - universal Linux installer can now be used on FreeBSD (via Linux
+    compatibility mode);
+  - updated unrar to v5.50;
+  - more robust news server connection test;
+  - enhancements in NServ:
+        - memory cache to reduce disk load during speed tests - new command line
+          switch "-m";
+        - speed control - new command line switches "-w" and "-r";
+        - show IP address of incoming connection;
+  - changed default location of log-file;
+  - better handling of broken connections;
+  - removed obsolete or less useful options "SaveQueue", "ReloadQueue",
+    "TerminateTimeout", "AccurateRate", "BrokenLog";
+  - renamed option "LogBufferSize" to "LogBuffer";
+  - passwords of failed login attempts are no longer printed to log to improve
+    security;
+  - cookies in web interface are now saved with "httpOnly" attribute to improve
+    security;
+  - titles and duplicate keys in duplicate check are now case insensitive;
+  - added LibreSSL support;
+  - web interface now has a better icon for favorites or home screen of mobile
+    devices;
+  - improved duplicate detection for obfuscated downloads having files with
+    same subjects;
+  - direct rename and direct unpack are now active by default on new
+    installations, except for slow Linux systems;
+  - added advice for letsencrypt in option descriptions;
+  - fixed incorrect renaming in rar-renamer which could cause some downloads to
+    fail;
+  - fixed race condition in queue script coordinator which could cause crashes;
+  - fixed: post-processing parameters were sometimes case sensitive causing
+    issues;
+  - fixed DNS resolving issues on Android;
+  - fixed: backup servers not used on certain article decoding errors;
+  - fixed: when direct rename was active certain downloads with damaged
+    par2-files become paused at near completion and required manual resuming;
+  - fixed: crash when flushing article cache after direct rename;
+  - fixed: deleting active par-job may crash the program;
+  - fixed: functional tests may fail on Windows due to locked files;
+  - fixed: unpack using password file doesn't work on Windows;
+  - fixed: compiler error when building using GnuTLS;
+  - fixed: Linux installer failure on android emulator;
+  - fixed: options formatted as password fields when they shouldn't;
+  - fixed: slightly off article statistics after direct rename;
+  - fixed: NServ terminated if client interrupted connection;
+  - fixed: example pp-scripts may not work properly if nzbget password or
+    username contained special characters;
+  - fix in functional tests to not rely on sizes of externally generated files;
+  - fixed: option AuthorizedIP did not work with IPv6 addresses;
+  - fixed crash on certain malformed articles;
+  - fixed crash which could happen on Windows when reloading or terminating the
+    program;
+  - fixed logging of IPv6 addresses.
+
+nzbget-19.1:
+  - proper handling of changing category (and destination path) during direct
+    unpack; direct unpack now gracefully aborts with cleanup; the files will
+    be unpacked during post-processing stage;
+  - fixed: password protected downloads of certain kind may sometimes end up
+    with no files if direct unpack was active;
+  - fixed: rar-renamer mistakenly renamed some encrypted rar3 files causing
+    unnecessary repair;
+  - fixed: rar-renamer could not process some encrypted rar3-archives.
+
+nzbget-19.0:
+  - unpack during downloading:
+        - downloaded files can now be unpacked as soon as every archive part is
+          downloaded;
+        - new option "DirectUnpack" to activate direct unpacking;
+        - direct unpack works even with obfuscated downloads; option
+         "DirectRename" (see below) must be active for that;
+        - option "ReorderFiles" (see below) should be also active for optimal
+          file download order;
+        - direct unpack works for rar-archives; 7-zip archives and simply
+          splitted files are processed by default unpack module;
+        - direct unpack obviously works only for healthy download; if download
+          is damaged the direct unpack cancels and the download is unpacked
+          during post-processing stage after files are repaired;
+        - direct unpack reduces the time needed to complete download and
+      post-processing;
+        - it also allows to start watching of video files during download
+          (requires compatible video player software);
+  - renaming of obfuscated file names during downloading:
+        - correct file names for obfuscated downloads are now determined during
+          download stage (instead of post-processing stage);
+        - downloaded files are saved into disk directly with correct names;
+        - direct renaming uses par2-files to restore correct file names;
+        - new option "DirectRename" to activate direct renaming;
+        - new queue-event NZB_NAMED, sent after the inner files are renamed;
+  - automatic reordering of files:
+        - inner files within nzb reordered to ensure download of files in
+          archive parts order;
+        - the files are reordered when nzb is added to queue;
+        - if direct renaming is active (option "DirectRename") the files are
+      reordered again after the correct names becomes known;
+        - new option "ReorderFiles";
+        - new command "GroupSortFiles" in api-method "editqueue";
+        - new subcommand "SF" of remote command "-E/--edit";
+  - new option "FileNaming" to control how to name obfuscated files (before they
+    get renamed by par-rename, rar-rename or direct-rename);
+  - TLS certificate verification:
+        - when connecting to a news server (for downloading) or a web server
+         (for fetching of rss feeds and nzb-files) the authenticity of the
+          server is validated using server security certificate. If the check
+          fails that means the connection cannot be trusted and must be closed
+          with an error message explaining the security issue;
+        - new options "CertCheck" and "CertStore";
+        - official NZBGet packages come with activated certificate check;
+        - when updating from an older NZBGet version the option CertCheck will
+          be automatically activated when the settings is saved (switch to
+          Settings page in web-interface and click "Save all changed");
+  - authentication via form in web-interface as alternative to HTTP
+    authentication:
+        - that must help with password tools having issues with HTTP
+          authentication dialog;
+        - new option "FormAuth";
+  - drop-downs (context menus) for priority, category and status columns:
+        - quicker changing of priority and category;
+        - easier access to actions via drop-down (context menu) in status
+          column;
+  - extensions scripts can now be executed from settings page:
+        - script authors define custom buttons;
+        - when clicked the script is executed in a special mode and obtain extra
+          parameters;
+        - example script "Email.py" extended with button "Send test e-mail";
+  - on Windows NZBGet can now associate itself with nzb-files:
+        - use option in Windows installer to register NZBGet for nzb-files;
+  - unrar shipped within Linux package is now compiled with "fallocate" option
+    to improve compatibility with media players when watching videos during
+    downloading and unpacking;
+  - support for HTTP-header "X-Forwarded-For" in IP-logging;
+  - improvements in RSS feed view in phone mode;
+  - set name, password and dupe info when adding via URL by click on a button
+    near URL field in web-interface;
+  - backup-badge for items in history similar to downloads tab;
+  - show backup icon in history in phone theme;
+  - added support for ECC certificates in built-in web-server;
+  - save changes before performing actions in history dialog;
+  - proper exit code on client command success or failure.
+  - added host name to all error messages regarding connection issues;
+  - new button "Volume Statistics" in section "News Servers" of settings page;
+    shows the same volume data as in global statistics dialog;
+  - new option "ServerX.Notes" for user comments on news servers;
+  - new parameters for api-method "servervolumes" as a performance optimization
+    measure to reduce amount of transferred data;
+  - new option to force connection to news servers via ipv4 or ipv6;
+  - removed unnecessary requests to news servers;
+  - updated unrar to v5.40;
+  - clear script execution log before executing script;
+  - added support for crash dumps on Windows:
+        - renamed option "DumpCore" to "CrashDump";
+        - new option "CrashTrace" to make it possible to disable default
+          printing off call stack in order to produce more relevant crash dumps;
+  - fixed: startup scheduler tasks can be executed again;
+  - fixed: "fatal" messages when compiling from sources.
+  - fixed: per-nzb download statistics could be wrong if the program was
+    reloaded during downloading.
+  - fixed crash which may happen between post-processing steps;
+  - fixed: asterix (*) was sometimes passed as parameter to extension scripts
+    (Windows only);
+  - fixed potential crash during update via web-interface.
+
+nzbget-18.1:
+  - fixed: crash during download caused by a race condition;
+  - fixed: sleep mode did not work on Windows;
+  - fixed: queue was not saved after deleting of queued post-jobs;
+  - fixed: possible crash at the end of post-processing;
+  - fixed: "undefined" in reorder extension scripts.
+
+nzbget-18.0:
+  - automatic deobfuscation of rar-archives without par-files:
+        - obfuscated downloads not having par-files can now be successfully
+          unpacked;
+        - also helps with downloads where rar-files were obfuscated before
+          creating par-files;
+        - new options "RarRename" and "UnpackIgnoreExt";
+  - multi post-processing:
+        - in addition to classic post-processing strategy where items are
+          processed one after another it is now possible to post-process
+          multiple items at the same time;
+        - new option "PostStrategy" to choose from four: sequential, balanced,
+          aggressive, rocket;
+        - in "balanced" strategy downloads needing repair do not block other
+          items which are processed sequentially but simultaneously with
+          repairing item;
+        - in "aggressive" mode up to three items are post-processed at the same
+          time and in "rocket" mode up to six items (including up to two repair
+          tasks);
+  - unified extension scripts settings:
+        - options "PostScript", "QueueScript", "ScanScript" and "FeedScript"
+          were replaced with one option "Extensions";
+        - users don't need to know the technical details os extension scripts as
+          all scripts are now can be selected at one place;
+        - easier activation of complex extension scripts which previously needed
+          to be selected in multiple options for their proper work;
+  - reordering download queue with drag and drop in web-interface:
+        - new actions "GroupMoveBefore" and "GroupMoveAfter" in API-method
+          "editqueue";
+  - priorities are now displayed as a column instead of badge; that makes it
+    possible to manually sort on priority;
+  - removed vertical lines in tables; looks better in combination with new
+    priority column;
+  - keyboard shortcuts in web-interface;
+  - improved UI to prevent accidental deletion of many items:
+        - visual indication of records selected on other pages;
+        - extra warning when deleting many records from history;
+  - additional options in "custom pause dialog";
+  - better handing of damaged par2-files in par-renamer:
+        - if par-renamer can't load a (damaged) par2-file then another par2-file
+          is downloaded and par-renamer tries again;
+        - reverted non-strict par2-filename matching to handle article subjects
+          with non-parseable filenames;
+  - better handling of obfuscated par-files;
+  - splitted option "Retries" into "ArticleRetries" and "UrlRetries"; option
+    "RetryInterval" into "ArticleInterval" and "UrlInterval";
+  - scheduler tasks can be started at program launch:
+        - use asterisk as TaskX.Time;
+  - graceful termination of scheduler scripts:
+        - scripts receive signal SIGINT (CTRL+BREAK on Windows) before
+          termination;
+  - added support for nZEDb attributes in rss feeds;
+  - better cleanup handling: if parameter "unpack" is disabled for an nzb-file
+    the cleanup isn't performed for it;
+  - fields containing passwords are now displayed as protected fields;
+  - showing password-badge for nzbs with passwords;
+  - allow control of what tab is shown when opening web-interface:
+    add "#downloads", "#history", "#messages" or "#settings" to the URL,
+    for example "http://localhost:6789/#history" or
+    "http://localhost:6789/index.html#history";
+  - functional testing to ensure program quality:
+        - implemented built-in simple nntp server to be used for functional
+          testing;
+        - created a number of tests;
+        - new features come with additional tests;
+  - improved API-method "append" in combination with duplicate check; method
+    returns nzb-id also for items added straight to history;
+  - removed parameter "offset" from api-method "editqueue":
+        - when needed the "offset" is now passed within parameter "Args" as
+          string;
+        - old method signature is supported for compatibility;
+  - improved error reporting on feed parse errors;
+  - highlighting selected rows with alternative colors;
+  - improved selecting of par2-file for repair;
+  - splitted config section "Download Queue" and moved many options into new
+    section "Connection";
+  - disabled SSLv3 in built-in web-server;
+  - multiple recipients in the example pp-script "EMail.py";
+  - added compatibility with openssl 1.1.0;
+  - fixed TLS handshake error when using GnuTLS;
+  - fixed: sorting of selected items may give wrong results;
+  - fixed: search box filter in feed view were not reset.
+
+nzbget-17.1:
+  - adjustments and fixes for "Retry failed articles" function, better handling
+    of certain corner cases;
+  - partial compatibility with gcc 4.8;
+  - removed unnecessary debug logging to javascript console;
+  - improved error reporting on certain file operations;
+  - corrected option description;
+  - corrected text in history delete confirmation dialog;
+  - fixed performance issue on certain Windows systems;
+  - fixed: root drive paths on Windows could not be used (for example
+    "NzbDir=N:\");
+  - fixed hanging after marking as BAD from queue script;
+  - fixed: old nzbget.exe was deleted even when installing into a new directory
+    (Windows only);
+  - fixed: compilation error if configured with unit tests but without par-module;
+  - fixed crash on malformed articles;
+  - fixed javascript error on Chrome for Linux;
+  - fixed compilation error if configured without TLS.
+
 nzbget-17.0:
   - reworked the full source code base to utilize modern C++ features:
         - with the main motivation to make the code nicer and more fun to work
