Improved: The way HostsCK starts has been completely re-written. This makes for a slightly faster start time
but more importantly reduces the chance of errors. The read time for reading the Hosts remains the same Improved: Search for duplicate entries has been made more compatible with Windows 10.
Some users were getting errors and a program crash. If that happens now HostsCK will check for duplicates in a safer
way but the GUI will become unresponsive Improved: The language changer is completely re-written and you can now download new language files or updates
to languages if available Improved: Textbox right-click menu detects if selected text can be saved to the saved sites or added to the
whitelist more logically Improved: The way HostsCK comes out of full mode and when exiting the built in browser has been re-written so
that the transition to the forms normal state is smoother Added: Disable auto adding 0.0.0.0 or 127.0.0.1 to a new line from the right-click menu Added: Ctrl+F in the main text box gives focus to the search box Added: Ctrl+S in the main text box saves the Hosts file. Can be changed in Settings > Input Added: American language file. (Thanks Chris Newman) Changed: About form re-designed Removed: HostsCK no longer checks for Windscribe VPN and keeps the Hosts writable if it is
detected. This was meant as a temporary fix for several users before the release of version 2.2.9 Removed: Delete cookies setting Fixed: HostsDE not updating the Hosts under certain conditions Fixed: HostsDE not adding whitelist when updating the Hosts Fixed: Edits to the Hosts file were ignored after using the search function. (Thanks Виталий) Fixed: Bug that prevented HostsCK checking for updates to the Microsoft Extra blocks list Fixed: If HostsCK disabled the Hosts file and a VPN created one, HostsCK could not re-enable the Hosts.
HostsCK will now enable the Hosts from the dis file but changes made by the VPN while disabled will be lost Fixed: “Search Next” button text could be missing. (Thanks Liz) Fixed: Write error when saving a site to the whitelist (Thanks Francis Béringer)
Version 184.108.40.206 – 20 May 2019
Fixed: Internet Explorer loading when HostsDE checked for a Hosts update while a VPN client was connecting or had disabled an internet connection. Fixed: HostsCK crash when launching the Hosts update server in the default browser. Added: Autosave setting. Open or drag and drop a Hosts file into HostsCK and it will be
automatically saved. HostsDE, if set to check for mvps Hosts updates, will download and save the Hosts
update when an update becomes available. Autosave is disabled by default. Go to ” Settings > Backup & Saving ”
to toggle autosave. Added: Shortcut key for full view (F11). Changed: Changed internet connection ping from 220.127.116.11 to 18.104.22.168 as several users reported
problems with HostsCK and HostsDE detecting an internet connection. Improved: Colour schemes re-written. Each scheme is named and the scheme colours are extended

Version 126.96.36.199 – 11 March 2019
Added: Setting in Settings > Input to automatically add 0.0.0.0 and block an address when pasting a web
address into the text box. E.G. “https://redisoft.uk/privacy-policy/” is pasted as “0.0.0.0 redisoft.uk”. Added: Setting in Settings > Misc to warn that Hosts is disabled when HostsCK exits. Added: HostsCK checks that the Hosts file can be edited and is not locked by another program when it
starts. See Help Added: Added font colouring for “# My Saved Sites”, “# Start Of Microsoft Blocks #” and
“# Start Of EXTRA Microsoft Blocks #” orange, lime and red respectively. Added: “View List” Link to view the Microsoft extra blocks list in your text editor.

extra blocks. Fixed: Fixed the English language file getting corrupted during install or update in certain cases. Fixed: Fixed a memory leak in HostsDE. Improved: HostsDE logging and MVPS server check. Improved: Only the domain name of a web address gets pasted into the text box.
E.G. “https://redisoft.uk/privacy-policy/” becomes “redisoft.uk” when using the Paste menu item to paste a
web address into the text box.
Ctrl+V overrides this behaviour so the full address gets pasted. Changed: Check Hosts is disabled when restoring a Hosts backup until that backup has been saved.

Version 18.104.22.168 – 12 January 2019
Fixed/Workaround: Windows update KB4481480 (Security and Quality Rollup for .NET Framework)
has broken HostsCK visual styling.

and deletes the registry key HostsDE creates if it is set to run when Windows starts. Updated: The HostsCK Install program has been updated to conform to Microsoft
guidelines. This means that links to the Uninstall HostsCK shortcut and the HostsCK license
are no longer in the HostsCK Start Menu folder. A link to the uninstaller is now in the
HostsCK program files directory and can still be easily uninstalled from the Windows
control panel. Removed: HostsCK can no longer be sent to the system tray to protect the Hosts
file as this is now handled by HostsDE.
Version 184.108.40.206 – 09 November 2018
