[gfarm-announce:100279] Gfarm version 2.4.2 released

Hi all,

We are pleased to announce the release of

 * Gfarm file system version 2.4.2,
 * Gfarm2fs version 1.2.3,
 * Gfarm GridFTP DSI version 1.0.2.


This release supports extended access control list, and federation of
Gfarm file systems by linking using Gfarm URL symbolic links.

If you used gfarm2fs version 1.2.2 without disabling extended
attribute functionality, file permissions of created files may be
incorrect.  To fix them, execute gfarm2fs_fix_acl.sh after installing
gfarm2fs version 1.2.3.

	% gfarm2fs_fix_acl.sh

This release also includes many updates and some bug fixes.  We
strongly recommend to upgrade to this version.
