　　Version 5.50

　　1. 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.

　　If you prefer RAR 4.x format by default, use "Create default..."

　　button on "Compression" page of WinRAR settings and set "RAR4"

　　in the displayed dialog.

　　This change affects only new clean installs. If you already saved

　　RAR format in the default compression profile in previous versions,

　　WinRAR respects stored settings.

　　2. Use "Set master password" button in "Organize passwords" dialog

　　to encrypt saved password records and protect them from unauthorized

　　access.

　　If saved passwords are protected with master password, you need to

　　enter the master password and press "OK" in password prompt to access

　　them. If entered password does not match the master password,

　　it is treated as a usual password for archive operations.

　　Once entered, the master password is valid until WinRAR is closed.

　　Close WinRAR and open it again after specifying the master password

　　if you wish to see how protection works. Enter a valid and then

　　empty master password to remove encryption from previously protected

　　password records.

　　This WinRAR version uses a new data format for password organizer,

　　so passwords stored in "Organize passwords" dialog are not readable

　　by older versions. It does not affect archive encryption formats

　　and encrypted archives are compatible with previous WinRAR version.

　　Organizer data is converted to a new format only when you save it

　　and not immediately after installing WinRAR.

　　3. 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.

　　Once entered, the master password is valid until WinRAR is closed.

　　Close WinRAR and open it again after specifying the master password

　　if you wish to see how protection works.

　　4. 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.

　　5. Added extraction support for .LZ archives created by Lzip compressor.

　　6. 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.

　　7. 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".

　　8. 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.

　　9. New "File types to open as archives first" option

　　in "Settings/Compression". 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 in file

　　management mode. Examples of such files are .docx or self-extracting

　　.exe archives. You can instruct WinRAR either to open such files

　　as archives first or to execute or open them in associated programs.

　　Default settings are to open self-extracting exe and to run

　　other types of archives with non-archive extension.

　　Regardless of these options, you can always open any such

　　archive file by pressing Ctrl+PgDn on its name in WinRAR file list.

　　Default folders for archives and extracted files are moved

　　from "Settings/Compression" to "Settings/Paths".

　　10. New "Copy full names to clipboard" command in "File" menu

　　places full names of selected files to clipboard.

　　11. Changes in the context menu displayed when right clicking

　　the file list in WinRAR:

　　a) several commands, which are also present on the toolbar

　　or in main menu, such as "View" and "Repair", are removed

　　from this context menu;

　　b) "Copy full names to clipboard" command is added;

　　c) "Run" for executables, "Open in associated application"

　　for associated files and "Show archive contents" for archives

　　are added. They allow to choose a way to process SFX archives

　　and archive files with non-archive extensions.

　　These items are present only in the file management mode

　　and are not available inside of archives.

　　12. LZ and ZIPX are added to list of associations in Settings/Integration

　　dialog.

　　13. LZ and ZIPX extensions are added to default list of formats for

　　-ms switch ("Specify file types to store") invoked without parameters.

　　14. You can specify 'f' charset value in -sc switch to use UTF-8

　　encoding. For example:

　　rar a -scfl arcname @filelist.txt

　　to read contents of filelist.txt as UTF-8 text.

　　15. 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.

　　16. 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.

　　17. 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.

　　18. File path information is displayed if mouse pointer is placed over

　　a name of archiving file in the operation progress window.

　　19. Name of currently active compression profile is displayed

　　in the archiving dialog above "Profiles..." button.

　　20. 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.

　　21. Bugs fixed:

　　a) fixed crashes and security vulnerability when unpacking corrupt

　　RAR archives;

　　b) WinRAR failed to unpack files in ZIP archives compressed

　　with XZ algorithm and encrypted with AES;

　　c) 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;

　　d) SFX archive extraction progress was incorrect in case of

　　multivolume SFX archive with total volume size exceeding 4 GB;

　　e) 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;

　　f) 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.
