2013. május 24. Megjelent a WinRAR 5.0 beta 4

Ezúttal is kisebb hibajavításokat eszközöltek:

  1. If archiving operation cannot allocate memory required for compression
      dictionary, it automatically reduces the dictionary size.

   2. Decompression algorithm can store the dictionary in several memory
      blocks. It helps to unpack an archive on systems with high level
      of memory heap fragmentation, when no single memory block
      is large enough to fit the entire compression dictionary.
