                RAR - What's new in the latest version


   Version 2.90

   1. Now it is possible to use full file paths such as \path\name
      in the exclude lists and -x<name> switch when archiving. 
      Earlier versions understood only relative file paths here.

   2. New 'E' parameter for -ag switch denotes a day of year.
      For example: rar a -agEEE backup.

   3. To provide a reasonable tradeoff between compression and
      reliability, RAR resets solid statistics between volumes
      only if sufficient data (about 4 MB) had been processed since 
      the last reset.

      You may use two new switches to change this default behaviour.
      Switch -sv forces RAR to always reset statistics, regardless
      of volume size, when -sv- disables such reset at all times.

      Switch -sv- supersedes -sd, though the latter is also recognized
      by RAR for compatibility purposes.

   4. The choice "Never" is added to the file overwrite request
      displayed by console mode RAR. Style of console RAR requests
      is somewhat altered.

   5. File lists (@listfile parameters of the command line) may now
      contain comments preceeded by // characters. For example:

      c:\work\doc\*.txt         //backup text documents
      c:\work\image\*.bmp       //backup pictures


   Version 2.80

   1. Command 's-' allows to remove SFX module from SFX archive.

   2. Switch '-ag' supports two new format parameters:

      a) 'W' - a number of the current week in a year;

      b) 'A' - a number of the current day in a week.
         Weeks start with Sunday.

   3. New switch '-k' - lock archive.

   4. New switch '-vp' - pause after each volume.

   5. You may specify the recovery record size as a percentage of
      the total archive size in 'rr' command and '-rr' switch.
      For example, -rr3%

   6. New -ep2 switch - store full file paths when archiving.

   7. Switch -sv is removed, now RAR by default creates independent
      volumes. You may override it using the new -sd switch, but note
      that it reduces your chances to restore a part of data in case
      of archive damage.

   8. Now RAR also searches for files .rarrc, rarfiles.lst and rarreg.key
      in /etc directory. SFX modules can be put to /usr/lib or
      /usr/local/lib. All these files can be also placed to user's
      home directory as before.

      The distributive includes makefile to simplify installation.
