Version 4.00

1. RAR decompression speed is improved. Depending on data type,
decompression can be up to 30% faster than in previous versions.

Both the general RAR algorithm and most of special RAR multimedia
methods benefit from this improvement. The only module of RAR
algorithm, which is not affected, is "Text compression" method.

2. Changes in ISO support:

a) UDF support is upgraded to UDF 2.50 revision. It makes possible
to unpack most of Blu-ray ISO files;

b) when browsing UDF ISO file, UDF revision number is displayed
after the "UDF" format name in WinRAR address bar
and in archive information dialog;

c) WinRAR sets the folder modification date when unpacking folders
stored in UDF and ISO9660 files.

3. Changes in password dialog:

a) WinRAR uses the same format of password dialog both when archiving
and extracting, so "Show password" option is available also
when extracting;

b) "Organize passwords..." button in password dialog provides
access to password organizer interface, where you can specify
your frequently used passwords. You will be able to access these
saved passwords using the drop down list or autocomplete feature
in password dialog.

It is important to know that saved passwords are not encrypted
and anybody having access to your computer can view them.
Use "Organize passwords" feature only if your computer is
protected from unauthorized access;

c) "Use for all archives" option is available in password dialog
when unpacking several archives at once. You can utilize it
to apply an entered password to all archives.

If you use this option with an empty password, WinRAR will skip
all encrypted archives;

d) Unlike previous versions, the password from default compression
profile is not used for extraction.

If you wish to use the same password for all extracting archives,
press "Organize passwords..." button in the password dialog
and define a new password entry, specifying "*" file mask
in "Select for archives" field.
