Original Bulletin:

- --------------------------BEGIN INCLUDED TEXT--------------------

7-Zip 18.05 was released.

7-Zip for 32-bit Windows:

7-Zip for 64-bit Windows x64:

What's new after 7-Zip 18.01:

The speed for single-thread LZMA/LZMA2 decoding was increased by 30% in
  x64 version and by 3% in x86 version.

7-Zip now can use multi-threading for 7z/LZMA2 decoding, if there are
  multiple independent data chunks in LZMA2 stream.

7-Zip now can use multi-threading for xz decoding,
  if there are multiple blocks in xz stream.

The speed for LZMA/LZMA2 compressing was increased by 8% for fastest/fast
  compression levels and by 3% for normal/maximum compression levels.

7-Zip now shows Properties (Info) window and CRC/SHA results window
as "list view" window instead of "message box" window.

Some improvements in zip, hfs and dmg code.

Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode
  in Windows 10 because of some BUG with "Large Pages" in Windows 10. 

Now 7-Zip doesn't use "Large Pages" on Windows 10 up to revision 1709 (16299).

The vulnerability in RAR unpacking code was fixed (CVE-2018-10115).

Some bugs were fixed.

New localization: Kabyle.
