1. Now by default WinRAR skips symbolic links with absolute paths
in link target when extracting. You can enable creating such links
with "Allow absolute paths in symbolic links" option on "Advanced"
page of extraction dialog or with -ola command line switch.
Such links pointing to folders outside of extraction destination
folder can present a security risk. Enable their extraction only
if you are sure that archive contents is safe, such as your own backup.
2. Bugs fixed:
a) if several files from different folders were selected
and extracted using "Flat folders view" file list mode
and "Extract relative paths" extraction option, WinRAR could
truncate paths of some of these files. It did not happen
if entire file list contents or a single file was selected.
