I can post the changelog. Its too much to mention. 

As you can see, its quite a lot. 

Really, having this stable version would be great in the repos. I dont think its been up to date since I started using linux quite a few years ago. haha

********************************************

4.2.1
When removing shortcuts or virtual drives from the Configure window, make sure desktop icons, menu entries, etc. are also removed.
fix Python's VersionLower (infinite source of bugs)
Update © in about box LP: #1160801
Fix a huge problem in bug reporting I introduced in 4.2... I thought it tested it well, this is depressing. Without testers, without users testing beta versions, it seems there's no way to get bugfree releases.
(experimental) enable display of beta scripts by default, differenciate them in lists using a reddish background
4.2
Huge icons download speedup by reusing a single HTTP connection
Make sure debug mode is disabled when using playonlinux --run; Debug may still be used in playonlinux-bash though
Make sure entered prefix name contains no space or slash during manual installations
POL_System_wget: make sure the pipelined wget exitcode is not masked by grep's one
POL_System_wget: interpret wget exitcodes
genere_icone(): pick the right icon instead of Wine generic one (reported by Simon/excalibr on IRC) (#1815)
(experimental) WINEDEBUG prefix setting, modify the amount of logging when debugging is enabled. I'm not sure of the right scope, should it be per-shortcut, like the old "enable debugging" flag, or even global?
POL_SetupWindow_shortcut_creator: use executable name as default shortcut name
sort shortcuts case insensitively in main window so that lowercase doesn't end up at the bottom
bug report: insert basic questions to answer in the bug report
add "Report a problem" in shortcut-related actions in the side panel
do not ask for confirmation to close PlayOnLinux if there's no program started
do not suggest bug reporting if a script has been canceled by the user because a prefix already existed
virtual drive removal should now overpass bad directory rights (caused by WMP9 for example) (#1732)
POL_System_HomeSpaceLeft fix for df multiline output (#1890)
added POL_System_UserRootSpaceLeft, in case ~/.PlayOnLinux is a symlink or a mount
use POL_System_UserRootSpaceLeft in POL_System_EnoughSpace
if exists, look for mounted devices in /media/$USER/ directory (Ubuntu Quantal, #1893)
manual_install: don't call POL_Wine_PrefixCreate on patch installation
irc: only warn about closing window when connected
Debug log all user inputs (POL_SetupWindow_textbox, etc.)
mainwindow.py: try to handle EINTR while reading from pol_update_list pipe (#1687)
DeletePrefix: if root is actually a symlink, just delete the symlink
gui_server.py: try to handle EINTR while accepting socket connections (#1687)
Fix typo (#1932)
POL_SetupWindow_download: accept a directory or a filename as 4th parameter
POL_Download: accept URLs with "query strings", that get included in local filename
(experimental) if missing, look for resources in winetricks cache before attempting download (#1963)
Add POL_Wine_DelOverrideDLL, POL_Wine_DelAppOverrideDLL (#1989)
POL_Wine_OverrideDLL and POL_Wine_AppOverrideDLL cleanups
Support creation of desktop menu entries (#1943). POL_Shortcut needs an extra parameter, categories, for the entry to be created. And similarly to NO_DESKTOP_ICON setting, a NO_MENU_ICON can be set to TRUE to prevent desktop menu entries from being created.

Fix bug in POL_Download_GetSize when redirected
Fix options parsing bug in POL_System_CheckFS
Log when NO_FSCHECK TRUE has been used
Tried to make it clearer that no-cd patches may be needed to get legal programs to work
Handle prefix overwrite in POL_Wine_PrefixCreate (Overwrite/Erase/Abort)
POL_Download_Resource(): fix for $3 and $4 mixed up (#1651)
VersionLower: fix cases when 3rd component in version strings is missing ("1.4") or dot in development string ("1.4-dos_support_0.6")
Fixes to lib.playonlinux.VersionLower()
Set_Desktop: support Wine 1.5.16+ (#1710)
Try to make the purpose of install filters more obvious (#1652)
