WinRAR 5.50 (64-bit)

File association option for JAR files is off by default in WinRAR installer unless you enabled it earlier in previous WinRAR versions. You need to enable this option manually if you wish to associate WinRAR with *.jar.
Unless "Allow absolute paths in symbolic links" extraction dialog option or -ola command line switch are specified, WinRAR does not allow to extract symbolic links with ".." in target if any of link path components is an existing symbolic link itself. It is done to prevent bypassing WinRAR security checks with chains from several symbolic links.
Bugs fixed:
If "Add" command was used from inside of archive opened in WinRAR interface, "file not found" error could be issued for files which pathnames included spaces.
Fixed crashes when unpacking corrupt RAR archives.
"rar a arc. filename" command created "arc." archive with trailing dot instead of expected "arc" without any extension.
"New folder" button in extraction dialog selected a parent of newly created folder instead of such folder itself.
"Checksum error" could be mistakenly reported for some valid GZIP archives.

If it takes too much time to locate a destination path in extraction dialog folder tree, automatic search performed as user enters the path is cancelled. Lengthy search in large folders could interfere with user input in this dialog.
You can still force WinRAR to select the entered destination path in extraction dialog with "Display" button.
Bugs fixed:
The keyboard focus was not returned to "Settings/File list" dialog page after selecting the file list font.

Added support for Unix extended timestamp extra field (0x5455 extra field tag) in ZIP archives. Such timestamps are used by InfoZip to store UTC file time additionally to standard ZIP local time. Now WinRAR reads and sets such timestamps when extracting.
"Run", "Open in associated application", "Show archive contents" items are added to right click menu in WinRAR file list. So you can right click SFX archive or archive file with non-archive extension like .docx and choose if you wish to browse its contents, to run or open it. These items are present only in the file management mode and are not available inside of archives.
"File types to open as archives first" option is moved from "Settings/Archives" to "Settings/Compression". Now it works only outside of archives to avoid conflicts with "Settings/Viewer/ Unpack everything for" option.
Default folders for archives and extracted files are moved from "Settings/Compression" to "Settings/Paths" dialog page.
Bugs fixed:
Some files in TAR archives could be unpacked with full paths even if "Extract relative paths" option was enabled.

Previous versions ignored files with invalid UTF-8 names inside of ZIP archives. Now WinRAR extracts such files, even though their names may include arbitrary text after unpacking.
Bugs fixed:
5.50 beta 1 could crash when extracting some of broken RAR4 archives.
"Settings/Viewer/Unpack everything for" was ignored for files matching "Settings/Archives/File types to open as archives first" masks. Now it is changed, so "Unpack everything for" has a higher precedence for archived files. Files inside of archive matching "Unpack everything for" masks are processed according to that option even if they are also matched by "File types to open as archives first" masks.

WinRAR and command line RAR use RAR 5.0 archive format by default. You can change it to RAR 4.x compatible format with "RAR4" option in archiving dialog or -ma4 command line switch.
Use "Set master password" button in "Organize passwords" dialog to encrypt saved password records and protect them from unauthorized access.
Prompt proposing to set the master password is displayed when storing a password in compression profile. You can enter the master password to encrypt password data stored in Registry and protect it from unauthorized access. You will need to enter the master password in password prompt dialog to access such compression profile after that.
By default, WinRAR uses AES-256 in CTR mode to encrypt ZIP archives. While AES-256 is significantly more secure than ZIP 2.0 legacy encryption algorithm, it can be incompatible with some older unzip software. If compatibility with such tools is required, you can enable "ZIP legacy encryption" option in the password dialog or use -mezl switch in the command line mode.
Added extraction support for .LZ archives created by Lzip compressor.
Modern TAR tools can store high precision file times, lengthy file names and large file sizes in special PAX extended headers inside of TAR archive. Now WinRAR supports such PAX headers and uses them when extracting TAR archives.
New "Store modification time" option on "Time" page of archiving dialog can be used to prohibit storing the file modification time in RAR 5.x archives. Former "High precision modification time" option is replaced by "High precision time format".
New "Full paths in title bar" option in "Settings/General" dialog. If enabled, the full path of currently opened folder or archive is displayed in WinRAR title bar.
New "Settings/Archives" page provides "File types to open as archives first" group of options. Here you can define how Enter or double click on a file with non-archive extension and archive contents should be processed in WinRAR file list. Examples of such files are .docx or self-extracting .exe archives. You can instruct WinRAR to open such files as archives, to run them, to handle them similarly or differently inside and outside of archives, to never run specified file types even if they do not include any archived contents.
New "Copy full names to clipboard" command in "File" menu places full names of selected files to clipboard.
LZ and ZIPX are added to list of associations in Settings/Integration dialog.
LZ and ZIPX extensions are added to default list of formats for -ms switch ("Specify file types to store") invoked without parameters.
You can specify 'f' charset value in -sc switch to use UTF-8 encoding.
RAR "lt" and "vt" commands display file times with nanosecond precision. Such precision is used in RAR5 archives created by RAR/Unix 5.50 and newer. Archives created by WinRAR have 100ns file time precision.
Only '+', '-' and '1' precision modifiers are supported in -ts switch now. Use '+' to store the file time with maximum precision, '-' to omit the file time and '1' to store it with 1 second precision. Intermediate precision modes previously defined with '2' and '3' modifiers are not available in RAR 5.0 archive format and ignored by -ts switch.
If a wrong password is entered when unpacking an encrypted file in RAR5 archive, WinRAR proposes to enter a valid password for same file again instead of aborting extraction.
File path information is displayed if mouse pointer is placed over a name of archiving file in the operation progress window.
Name of currently active compression profile is displayed in the archiving dialog above "Profiles..." button.
If "Find" command is invoked from inside of archive subfolder, "File names to find" will include the path to this subfolder. So "Find" will search only starting from this subfolder.
Bugs fixed:
WinRAR failed to unpack files in ZIP archives compressed with XZ algorithm and encrypted with AES.
If "Windows progress bars" option in WinRAR settings was turned off and "Put each file to separate archive" archiving mode was used, "gold" part of total progress bar did not display the compressed data ratio correctly.
SFX archive extraction progress was incorrect in case of multivolume SFX archive with total volume size exceeding 4 GB.
If archived folder name included trailing spaces, if user selected and extracted some folders in non-root archive folder and if "Allow potentially incompatible names" extraction option was turned off, WinRAR could lose one or more leading characters in extracted folder name.
If only creation or only last access file time was stored in RAR5 archive with 1 second precision, such as with -ma5 -tsm- -tsa1 switches, this stored time was ignored when extracting.

- "Name encoding" submenu in "Options" menu allows to select encoding for archived file names. This selection affects archive browsing and extraction commands. You can use Ctrl+E keyboard shortcut to access this menu quickly. It can be useful when unpacking an archive without Unicode file names.
- If RAR recovery volumes (.rev files) are present in the same folder as usual RAR volumes, archive test command verifies .rev contents after completing testing .rar files. If you wish to test only .rev files without checking .rar volumes, you can select .rev files in WinRAR file list and apply "Test" only to them or run: rar t arcname.part1.rev in the command line.
- While NTFS file system permits file names with trailing spaces and dots, a lot of Windows programs fail to process such names correctly. If "Allow potentially incompatible names" option in "Advanced" page of extraction dialog is turned off, WinRAR removes trailing spaces and dots, if any, from file names when extracting. This option is turned off by default. Command line RAR also removes trailing spaces and dots when extracting unless -oni switch is specified.
- Previously "Synchronize archive contents" update mode(-as command line switch) aborted if some of archiving folders could not be read. Now WinRAR continues performing the operation and preserves archived files matching unreadable folders.
- WinRAR Shift+Del delete command can be used to delete folders containing non-standard file names with trailing spaces and dots. Usual delete to Recycle Bin also as Shift+Del in previous WinRAR versions cannot delete such folders.
- You can drag folders from folder tree panel and drop them to other programs or Desktop to copy or unpack them. Drag the archive icon in tree panel root to unpack the entire archive.
- "New folder" button in extraction dialog proposes a new folder name based on archive name instead of generic "New Folder".
- Command line RAR version information:
* if -iver switch is specified, RAR displays the version number and quits. You can run just "RAR -iver";
* "x86" or "x64" is displayed in Windows RAR version information both for -iver and in the copyright title for other commands.
- If -p switch is used without optional <pwd> parameter, a password can be also set with file redirection or pipe. For example: rar -p myarc.rar myfiles < psw.txt
- Command line RAR treats 'arcname.partN' as 'arcname.partN.rar' if 'arcname.partN' does not exist and 'arcname.part#.rar' exists.
- Improvements in 7z archives support:
* "Solid" status is correctly detected and reported for 7z archives in WinRAR "Info" command;
* dictionary size is displayed for LZMA and LZMA2 7z archives in WinRAR "Info" command;
* unknown packed size for files inside of 7z solid block is denoted as '?' instead of '0' when browsing the archive contents in WinRAR.
- Maximum comment length for RAR archives is increased from 64 to 256 KB. Since SFX script commands are stored in archive comment, it allows a longer main and license text in SFX archives.
- Size of default WinRAR viewer font is scaled up properly in Windows high DPI mode.
- Switch -scul can be used to process big endian UTF-16 list files as well, provided that they have a correct byte order mark. Previously it allowed only little endian file lists.
- Minimum supported Windows version is Windows XP SP3 now. WinRAR will not run in Windows XP without service packs.
- "Settings/File list/Allow all uppercase names" option is removed. This option was intended to simplify transition from MS DOS to Windows and is not needed anymore.
# Bugs fixed:
- WinRAR 5.31 x64 "Compress and email" command did not work with Microsoft Outlook x64;
- if WinRAR 5.31 version for one of right to left languages was installed in Windows with English or other not right to left system language, WinRAR could change Windows Explorer layout to right to left;
- if archive was stored in a folder without "Write" permission and if archive contents was extracted with drag and drop to a writable folder, WinRAR issued an unnecessary privileges elevation prompt.
