Version 5.91 beta 1

1. Dialogs are centered inside of WinRAR window similarly to WinRAR 5.80

and not inside of entire screen as in WinRAR 5.90.

2. When editing an archived file with external software, extra measures

are taken to reduce the probability of interfering with editor

and opening its temporary files while editor still may need them.

3. "Version to extract" field in archive properties opened from

Windows Explorer context menu provides the additional information

about ZIP compression and encryption algorithms, such as LZMA or AES.

This information was already available in WinRAR "Info" command,

but missed in archive information accessible from Windows Explorer.

4. "MS DOS" and "Unix" host OS types are recognized and included

for LZH archives in "Info" command. Previously the host OS field

was always "Unknown" for LZH archive format.

5. Files created by external editor and matching "Settings/Viewer/

Ignore modifications for" masks are never added to archive.

Previously WinRAR still added them if some file not matching

these masks was also created or modified.

6. Bugs fixed:

a) empty file names were displayed inside of some Unix LZH archives;

b) WinRAR could not process more than 999 7z volumes in a single set;

c) if user cancelled the user account control prompt after changing

"Integrate WinRAR into shell" option, a new state of this option

was displayed in "Settings" dialog, even though the actual state

of shell integration was not modified;

d) the main window size could be too small on the first run after

clean install with no previous WinRAR version present;

e) WinRAR could stop responding after editing an archived file

with external software in Windows 10 version 2004.
