 # = comment
 + = new feature
 * = improved feature
 ! = fixed bug
 - = removed feature
----------------------------------------------------------------

+: The NewsLeecher executable and the NewsLeecher setup archive
   is now digitally signed to avoid false positives by anti
   virus software, and to prevent security warnings during
   install and launch.
+: It's now possible to manually select which setup / data files
   NewsLeecher should load at startup, by pressing the F12 key
   while launching NewsLeecher.
*: Lots of smaller improvements.
!: Fixed bug where NewsLeecher would sometimes return an error
   when downloading very big articles.
!: Fixed small issue, where the groups listview article position
   wasn't always reset when entering a new usenet group.
!: Many smaller bugfixes.

#: --[ SuperSearch Updates Since Previous Release ]---------------
   Now that the article retention for the new SuperSearch engine
   is at 850 days, we've bumped the max limit for articles
   returned by SuperSearch as well. The limit has been bumped from
   15000 to 30000 SuperSearch search results.
   We've also improved the SuperSearch indexing turn-around time,
   so most indexed groups will be updated in realtime (every
   minute or faster).
   ---------------------------------------------------------------
*: Many smaller improvements here and there.
!: Fixed an issue where the download folder for an article could
   be set incorrectly, due to a new cross-post groups view feature
   introduced in the new SuperSearch engine.
!: Fixed bug where the optional posting signature could be garbled
   when posting a text message.
!: Lots of smaller bugfixes.

#: --[ SuperSearch with 850 Days of Retention ]-------------------
   This beta release connects to a brand new, and much improved,
   SuperSearch service engine. The new engine currently runs
   with 850 days of retention in the General category and
   more than 300 days of retention in the Erotica category,
   including all the alt.binaries.pictures* groups.
   Just like the old engine, the new engine supports true wildcard
   searching, and still uses the same Google-like syntax for
   searching. Note that advanced search features, such as specific
   Poster / Group searching haven't been enabled yet. Also,
   because the engine is brand new, it might contain bugs which will
   be corrected as fast as possible.
   ---------------------------------------------------------------
+: NewsLeecher will now mark collections as 'Sampled' instead of
   'Downloaded', if less than half of the articles in the
   collection have been downloaded. Note that this will only
   apply for articles downloaded with NewsLeecher v4.0 Beta 18 and
   newer releases.
*: Changed behaviour of the Ctrl+U shortcut, so pressing the
   shortcut keys once, will deactivate active groups, and
   pressing it twice in a row, will unload groups from memory.
*: NewsLeecher will now include articles with the following
   subject patterns into collections: *.t##, *.u##, *.v##, *.w##,
   *.x##, *.y## and *.z##.
!: When using the new "Update Latest [####] Headers" feature, and
   pressing cancel on the update dialog, NewsLeecher didn't cancel
   the update as it should.

+: Implemented a feature that makes it possible to fetch a user
   specified number of headers in subscribed groups.
*: It's now possible to unsubscribe groups from the groups
   suscription listview context menu.
!: Fixed a serious bug that caused recent betas of the
   NewsLeecher V4 series to incorrectly parse dates of headers
   from the month of May.
!: SuperSearching didn't work when clicking SuperSearch bookmarks,
   if the advanced nerdy tweak feature "SuperSearch Single Click
   Search" feature was set to false.

*: Further improved the 'Collections' algorithm, which is used by
   NewsLeecher to find articles that belong together.
!: After sorting an article view, NewsLeecher will now automatically
   make the pre-sort focused article (if any) visible again.
!: The 'Sort by Status Column' feature is now working again.
!: Fixed bug introduced in previous beta, where the group browsers
   article subject filter history was reset between app launches.

*: Improved the way NewsLeecher handles articles being added or
   removed from the transfer queue.
*: Various internal and visual improvements.
!: The group listview is now always auto-resorted when needed. In
   previous releases the sort order could be mixed up when using
   the article filters.
!: Fixed bug where user specified speed limits, set via the
   bandwidth slider, weren't consistent between relaunches of
   NewsLeecher.
!: Fixed bug where the 'Keep Opened Articles' feature didn't
   always work.
!: Many smaller bug fixes and corrections.

+: It's now possible to specify what action NewsLeecher should
   perform, when doubleclicking an article or an article
   collection in the 'Articles View' or the 'SuperSearch View'.
   The action can be setup at:
   Settings -> Interface -> Doubleclick to : ...
+: It's now possible to specify whether NewsLeecher should obey
   any setup pausing rules, when manually resuming transfers
   of articles in the transfer queue. Pressing Ctrl or Shift while
   resume articles, will make NewsLeecher obey pausing rules.
*: NewsLeecher now shows detailed backup information in the log,
   when triggering the backup function manually via the 'Tools ->
   Trigger Backup' menu.
*: The download counter label can now be switched on / off from:
   Settings -> Adv. Nerdy Tweaks -> GUI Download Counter Visible

   headers were being fetched while NewsLeecher was closed down.
!: Fixed bug that sometimes threw an exception when manually
   removing articles from the transfer queue.
!: The "Copy Subject to Clipboard" function didn't always work
   with the SuperSearch view. Fixed.

   system is enabled and set to backup NewsLeecher every 15
   minutes. The backup system can be switched on / off at:
   Settings -> Adv. Nerdy Tweaks -> Backup Enabled
   And the backup interval can be changed at:
   Settings -> Adv. Nerdy Tweaks -> Backup Interval in Minutes
+: The newly implemented backup system can be manually triggered
   from Menu -> Tools -> Trigger Backup
*: Various internal and visual changes here and there.

   NewsLeecher would sometimes pause the transfer queue when
   anti-virus software temporarily locked the files that
   NewsLeecher was downloading.

*: Re-enabled the possibility to change the download destination
   folder for queued articles.
*: For easier management and better overview, temporary download
   files are now placed in separate folder(s), specifically made
   for the temporary files. When downloads are completed,
   NewsLeecher will automatically cleanup the folders.
!: Fixed bug that sometimes (rarely) caused NewsLeecher to lock-up
   when Repair'n'Extract was used.
!: Shift+PageUp / Shift+PageDown didn't work in the NewsLeecher
   article views during the recent beta releases. Fixed.

#: Note that this beta release makes a small change to the
   cache file format. It is recommended that you make a backup
   of your NewsLeecher data before installing.
+: Added a "Copy to Clipboard" function to the log window toolbar.
   The function can be used to copy the visible part of the log
   window contents to the clipboard.
*: The time it takes to add articles to the transfer queue, has,
   in some extreme cases where the size of the transfer queue is
   very very large, been reduced substatially.
*: Optimized one of the transfer queues disk cache files,
   resulting in faster load / save time, and a ~10x reduction of
   size of that specific cache file.
!: Fixed bug introduced in beta 10, where the new article download
   save system didn't always work as expected.
!: Fixed bug where all group headers would be re-fetched from the
   server, if all locally stored group headers were manually
   deleted from cache, using the "Delete from Cache" feature.

   deleted like they were supposed to.
!: Fixed bug introduced in beta 10, where downloaded articles
   were sometimes (rarely) corrupted.

   fixed, etc.)

+: Added an option to show article parts information in the
   article listviews. The option can be turned on at:
   Settings -> Nerdy Tweaks -> Article Parts Visible in Listview
   Note that the feature can be turned on / off, by using the
   Shift+P keyboard shortcut.
*: << BIGGER IMPROVEMENT >>
   This release uses a new, and much more efficient, way to handle
   article downloads. This change should take of most of the
   temporary queue pauses that some users see, when downloading
   articles with NewsLeecher on a fast connection.
   Technically speaking, yEnc encoded articles are now written
   directly to the download destination folder, instead of being
   written to a temporary disk location first, whereas uuEncoded
   articles are now kept in a memory cache until all article parts
   are downloaded, whereafter the cache is flushed directly to the
   download destination folder.
*: The 'copy subject to clipboard' / 'copy poster name to
   clipboard' features now copies all selected articles to the
   clipboard, instead of only the first selected article.
*: The algorithm used to create article collections, has been
   improved a bit, making the colletion names better looking
   under certain circumstances.
*: NewsLeecer now includes *.srr files in article collections.
*: Lots of smaller improvements (improved compatibility with
   MAC/Wine and MAC/Crossover, etc.)
!: Fixed bug where fetching headers, while using the new 'turbo
   compressed headers' feature, would sometimes fail, if only
   a small number of headers were available for fetching.
!: Fixed bug where articles downloaded for reading (Open), were
   sometimes skipped, if the 'skip if file already exists' feature
   was enabled.
!: Fixed bug where Repair'n'Extract would sometimes fail if the
   Repair'n'Extract 'Date & Time Prefix Folder' feature was used.
!: Fixed bug introduced in a recent beta, where the max limit
   for article headers fetching was sometimes ignored.
!: Fixed issues where Repair'n'Extract would sometimes
   automatically unpause articles in the transfer queue, even
   though they were not part of any Repair'n'Extract sets.
!: Double-clicking downloaded articles in the listviews, didn't
   open the download article file, like it's supposed to.
!: Many smaller problems fixed (Socks firewall fix, etc.)

+: Implemented a 'Copy Selected Article Subject to Clipboard'
   feature. Can be accessed by popup menus, and 'Ctrl+C'
   shortcut.
+: Implemented a 'Copy Selected Article Poster Name to Clipboard'
   feature. Can be accessed by popup menus, and 'Shift+Ctrl+C'
   shortcut.
+: Implemented functionality to pause to download queue for a
   user-specified number of minutes. The new feature can be
   accessed from the Pause button context menu.
*: << Major Performance Improvement >>
   Major performance improvements when browsing articles in
   large usenet groups and/or when browsing articles on slow
   computers. These improvements fixes the most significant
   performance bottleneck remaining in NewsLeecher.
*: This release uses less system resources when downloading
   articles.
*: The overall performance in NewsLeecher has been improved due
   to internal low-level optimizations.
*: The "Delete From Cache" feature is now 1000% + faster.
*: Various smaller improvements. (Repair'n'Extract is now faster
   at handling files under some circumstances, etc.)
*: Small improvements to the 'Collections Pattern Detection' code,
   used by NewsLeecher when figuring out which articles should be put
   in which collections.
*: The "Group Cleaning" dialog, occasionally shown during close
   down, can now be turned off if wanted.
!: Fixed bug where the NewsLeecher hint windows flickered whenever
   lines were written to the log window.
!: Fixed bug where NewsLeecher sometimes miscalculated the
   'minimum disk space' settings, and paused the queue
   unnecessarily.
!: Fixed bug where Repair'n'Extract would sometimes delete
   downloaded articles, even if Repair'n'Extract unpack / move /
   copy operations has failed.
!: The 'Move Small Articles to Queue Top' setting was sometimes
   ignored. Fixed.

+: Native Header Compression:
   Native article header compression now supported through the
   usenet server 'XFEATURE' command.
   The feature can be turned off from: "Settings ->
   Adv. Nerdy Tweaks -> Article Download Allow XFEAT Compression".
   Not all usenet servers support this command. NewsLeecher will
   automatically check for support when it connects to the server,
   and use the feature if supported. When the feature is enabled,
   the 'header download' speed should be 2-10X times faster than
   usual.
+: Implemented physical disk cleanup for usenet group caches.
   It's possible to specify how much garbage a group cache must
   have before the cleanup routine is triggered. The setting
   can be accessed at:
   Settings -> Adv. Nerdy Tweaks -> Article Cache Max Garbage Pct
+: (Re)implemented the 'Add to Subject Ignore List' feature for
   the group headers view. It can be accessed from the popup menu.
+: (Re)implemented the 'Add to Poster Ignore List' feature for
   the group headers view. It can be accessed from the popup menu.
+: (Re)implemented the 'Select Smart' feature for the group
   browsing view, the SuperSearch Service view and the transfer
   queue. The comparison algorithm used by 'Select Smart' has also
   been improved a bit.
+: (Re)implemented the 'Select Poster' feature for the group
   browsing view, the SuperSearch Service view and the transfer
   queue.
+: (Re)implemented the 'Export to NZB' feature for the SuperSearch
   view.
+: It's now possible to post text replies to articles, directly
   from the SuperSearch view.
+: All leech methods available in the group article browsing view,
   are now also available in the SuperSearch view. Including all
   the 'special leech' commands.
*: The overall performance of NewsLeecher has been improved a lot
   due to internal optimizations.
*: Group article headers are now received in a separate CPU
   thread. Using this multithreaded approach to fecth headers,
   will make NewsLeecher run smoother on slower computer, while
   fetching headers.
*: When 'Opening' a selected article collection, NewsLeecher will
   now only open *.NFO article files within the collection,
   instead of the entire collection.
*: The progress bar view in the "Bots" listview, now also shows
   the download progress of the entire collections belonging to
   the downloading articles.
*: The "Number of New Group Headers at Server"-counters are now
   updated live, while fetching headers from groups.
*: Several optimizations to the internal structures in
   NewsLeecher, making the app run a bit smoother on slow systems.
*: Moved Socks Firewall setup to the Advanced Nerdy Tweaks
   settings page.
*: Improved the appearance of the Nerdy Tweaks dialog a bit.
*: Smaller visual improvements here and there.

   were sometimes reversed in order.
!: Fixed bug where the queue status text for downloading articles
   was sometimes incorrectly set to 'initializing'.
!: In the previous betas, the columns in the "all groups" listview
   were not sortable. Fixed.
!: NewsLeeecher would sometimes freeze for some seconds during
   starup. This has (most probably;) been fixed. Not 100% sure
   though.
!: When exporting articles to an NZB file, the article poster
   names were sometimes skipped. This has been fixed.
!: Sorting by the 'Download Folder' column in the queue listview
   didn't work properly. Fixed.
!: Smaller bugs fixed. (the adv. nerdy tweak
   'gui_show_popup_hints' didn't work in the previous beta, etc..)

+: The NewsLeecher license status is now, optionally, shown on the
   captionbar and titlebar.
   The option can be accessed from:
   Settings -> Adv. Nerdy Tweaks -> GUI_License_Status_On_Titlebar
*: It now possible to specify the spacing between texts in the
   NewsLeecher listview columns. The default spacing value is
   set to 1, whereas the spacing was 0 in previous releases.
   The setting can be accessed from:
   Settings -> Adv. Nerdy Tweaks -> Listview_Column_Spacing
*: Reworked the way the queues 'Pause' / 'Resume' features work
   on queued article collections.
*: Smaller improvements. (it's possible to enable the speed
   scheduler without opening the scheduler setup dialog, the
   filters dialog GUI has been improved, etc..)
!: In previous betas, Shift + PgUp and Shift + PgDn didn't work
   for selection entries. fixed.

   files if the files already exists in the download folders.
   The option can be accessed from:
   Settings -> Adv. Nerdy Tweaks -> Download_Skip_Existing_Files

   Optimized the group cache loading code. Depending on various
   parameters, the new group cache loading code is up to 500%
   faster in the code used in previous versions of NewsLeecher.
*: Simplified the Groups Browsing popup menu and the SuperSearch
   popup menu.
*: Improved the 'Adv. Nerdy Tweaks' dialog interface a bit.
*: Lots of smaller improvements.

   'quick search' filters have been reset in this release.
+: Added possibility to change colors of 'Downloaded', 'Paused',

*: <<< Performance Improvement >>>
   Optimized the handling of the Repair'n'Extract view. Certain
   parts of the code is now ~250 times faster than before. This
   optimization should fix the temporary freezing some users see
   when having many entries in the Repait'n'Extract view.
*: <<< Performance Improvement >>>
   Improved the way NewsLeecher detects whether articles should
   be marked as 'downloaded'. The new way of detecting, is ~500
   times faster than the old way.
*: Simplified the Repair'n'Extract toolbar a bit.
*: Smaller improvement here and there. (made the SuperSearch query
   box a little wider, etc..)
!: The limits set for maximum number of headers to fetch on usenet
   group updates were not working in the previous betas. This has
   been fixed.
!: NewsLeecher didn't work properly under certain system locales,
   such as Japanense and Korean. This has been fixed.

   sometimes freeze for some time. This has been fixed.
!: Many smaller fixes. (size of collections in transfer queue were
   sometimes incorrect, etc..)

#: This release uses a new format for setup and configuration
   files. NewsLeecher will automatically detect earlier formats
   of the setup and configuration files and upgrade to the new
   format without any user intervention. But note that older
   versions of NewsLeecher will not be able to identify the new
   format, so downgrading will reset most settings. It is
   therefore recommended that you backup your NewsLeecher
   installation before installing this release, just in case
   anything goes wrong.
+: Reintroduced a lot of the features which were removed in the
   first NewsLeecher version 4.0 betas. The reintroduced features
   include listview font name and size configuration, listview
   entry height configuration, turning on / off the speedgraph
   background logo etc..
+: Added 'Notify on New Final Release' and 'Notify on New Beta
   Release' checkboxes to the news-page toolbar.
+: The Repair'n'Extract status column now shows the extraction
   speed for extracting archives in MB/s
+: Lots of 'advanced user' tweaks have been added to the
   setup dialog. The settings can be accessed from 'Setup ->
   Advanced Nerd Tweaks'. The new tweaks include listview entry
   color shade settings for sorted columns and collections, the
   possibility to set the size of the speedbar on the tray icon,
   etc..
*: NewsLeecher uses a new format for the setup and configuration
   files. Reading from, and writing to, the new format is between
   10 and 1000 times faster than with the old format. And as
   NewsLeecher reads and writes a lot of settings during
   operations, this change will have a positive impact on the
   overall performance.
*: Totally re-organized the setup dialog, to make it much easier
   to configure and run NewsLeecher from scratch. All of the non-
   essential options and settings have been moved to a new setup
   section called 'Advanced Nerd Tweaks'. NewsLeecher will run
   fine without playing around with this new section, but the
   settings and options can be tweaked to optimize and personalize
   NewsLeecher further if wanted.
   Due to this new section, the rest of the setup dialog,
   containing more essential NewsLeecher settings and options, has
   been greatly simplified.
*: Repair'n'Extract will now extract archives ASAP, instead of
   waiting until all Repair'n'Extract entries have been verified.
*: Improved the 'Filters Dialog' by replacing the filters listview
   control with a memo control. The memo control allows much
   faster editing of filters, aswell as batch copy/paste
   operations.
*: All 'Group Browsing' settings and filters have been moved to
   the setup dialog. The 'Group Browsing' setup dialog can be
   accessed fast by clicking the 'Settings' button on the 'Group
   Browsing' toolbar.
*: Improved the easy-of-use of the download counter, located on
   the status bar.
*: Lots of minor improvements. (Changed the standard pixel height
   of listview entries, new graphics in setup dialog, etc.)
!: Fixed serious bug introduced in previous betas, where
   NewsLeecher sometimes totally screw up the download destination
   folder path when downloads were initiated from NZB files and
   the 'Download to Groupname Folder' option was used at the same
   time.
!: Fixed bug where the NewsLeecher article header retrieval
   function would skip certain headers, because their subjects
   used a format which wasn't recognized by NewsLeecher.
!: Fixed bug where NewsLeecher would sometimes pause the transfer
   queue automatically when the scheduler is active:
   http://www.newsleecher.com/forum/viewtopic.php?t=18728

   feature and added a shortcut to access it (CTRL+Y).
*: Improved 'Leech Specify' to include an eventual group folder,
   as set in group properties dialog, when setting the default
   download destination folder.
*: A few minor improvements here and there.
!: Fixed bug introduced in V4 Beta 1, where the 'Leech Specify'
   feature didn't include the groupname in the default destination
   folder, even though the 'download to groupname folder' option
   was used.
!: When updating groups, not all articles were marked as 'new',
   even though they contained new article parts.
!: Fixed bug introduced in previous beta, where Repair'n'Extract
   would delete non-archive files instead of moving them to the

   systems.
*: When pressing the SuperSearch 'Stop' button, NewsLeecher would
   show a dialog stating that you have just pressed the 'Stop'
   button. That dialog has been removed.
*: Lots of internal code clean-up improvements. These improvements
   should improve both NewsLeecher speed and stability.
*: Many smaller improvements, incl. a few visual ones, like the
   text / hints on the view tabs.

#: Note that this NewsLeecher release introduces a completely new
   article cache system which is significantly different from the
   previously used cache system. Because of the major change in
   the format of the cache, it will be necessary to re-fetch
   headers for any subscribed usenet groups the first time
   NewsLeecher V4.0 Beta is used.
#: Because of the early beta stage of this NewsLeecher V4 release,
   it is recommended that you keep settings for NewsLeecher V4
   separate from settings for earlier releases of NewsLeecher that
   you might have installed.
   To setup a separate NewsLeecher V4 settings folder, check:

   You can of course also take the chance and simply install this
   release on top of your currently installed NewsLeecher copy,
   and hope things work out ;) Doing that will probably also work
   fine.
+: *MAJOR ADDITION*: NewsLeecher now fully supports collections
   (also known as threading) of binary articles. The collections
   feature will group associated binary articles together and
   present them as a single article entry in the NewsLeecher
   listviews, instead of multiple separate entries.
   Collections are supported by the entire NewsLeecher interface.
   That is the article browser, the SuperSearch service and the
   NewsLeecher download queue.
   Besides providing better article overview, the collections
   feature also speeds up group loading by 500%+ for most
   binary groups aswell as keeping memory usage much lower than
   what previous NewsLeecher releases does.
+: It's now possible to specify separate paths for NewsLeecher to
   store settings and temporary files. For more info on how to
   set the paths, check this URL:
   http://www.newsleecher.com/forum/viewtopic.php?t=18326
+: NewsLeecher will now ask for confirmation before closing down,
   if Repair'n'Extract is actively working on one or more file
   sets.
*: This NewsLeecher release supported mixed-case subject lines
   returned by SuperSearch. Earlier releases would show all
   subject lines returned by SuperSearch in lowercase.
*: More parts of the internal Windows Explorer are now multi-
   threaded. This brings a significant speed improvement when
   browsing folders containing many sub folders.
*: The entries in 'Max Days' SuperSearch filter have been re-
   organized to better suit the new elevated SuperSearch
   retention.
*: Improved 'Leech Specify' dialog to be more intuitive and
   easy to use.
*: Many smaller improvements. (The mouse hint text for the
   SuperSearch favorite buttons now shows the query to be
   searched, SSL libraries updated, etc.)
!: The entire NewsLeecher codebase has been probed for memory
   leaks. Lots of leaks have been fixed.
!: Fixed a bug prevented NewsLeecher from properly updating groups
   containing an extremely large amount of headers (such as alt.
   binaries.boneless). The bug was only triggered on a few usenet
   servers.
!: Fixed bug that somestimes caused NewsLeecher to hang on
   shutdown.
!: Many smaller fixes. (The Repair'n'Extract verification state
   was sometimes reset between sessions, GUI tweaks, etc.)
-: Removed option for turning off error checking of downloaded
   articles as there's no reason not to check them for errors.
-: Removed outdated option to cancel errornous articles from being
   downloaded as the option could cause some confusion. Also the
   introduction of PAR2files and the NewsLeecher Repair'n'Extract
   feature makes errornous files usable.
