You either need the first two files or the third and fourth, i.e., the gzip'ed version or the compressed version and the corresponding sig file. The PGP signature was created using the Sendmail Signing Key/2015, available on the web site (http //www.sendmail.com/sm/open_source/download/) or on the public key servers.

SENDMAIL RELEASE NOTES

This listing shows the version of the sendmail binary, the version of the sendmail configuration files, the date of release, and a summary of the changes in that release.

8.15.2/8.15.2   2015/07/03

If FEATURE(`nopercenthack') is used then some bogus input triggered

a recursion which was caught and logged as

SYSERR: rewrite: excessive recursion (max 50) ...

Fix based on patch from Ondrej Holas.

 

DHParameters now by default uses an included 2048 bit prime.

The value 'none' previously caused a log entry claiming

there was an error "cannot read or set DH parameters".

Also note that this option applies to the server side only.

 

The U= mailer field didn't accept group names containing hyphens,

underbars, or periods. 

Based on patch from David Gwynne

of the University of Queensland.

 

CONFIG: Allow connections from IPv6:0:0:0:0:0:0:0:1 to relay again.

Patch from Lars-Johan Liman of Netnod Internet Exchange.

 

CONFIG: New option UseCompressedIPv6Addresses to select between

compressed and uncompressed IPv6 addresses.  The default

value depends on the compile-time option IPV6_FULL:

For 1 the default is False, for 0 it is True, thus

preserving the current behaviour.  Based on patch from

John Beck of Oracle.

 

CONFIG: Account for IPv6 localhost addresses in

FEATURE(`block_bad_helo').  Suggested by Andrey Chernov

from FreeBSD and Robert Scheck from the Fedora Project.

 

CONFIG: Account for IPv6 localhost addresses in check_mail ruleset.

 

LIBMILTER: Deal with more invalid protocol data to avoid potential

crashes.  Problem noted by Dimitri Kirchner.

 

LIBMILTER: Allow a milter to specify an empty macro list ("", not

NULL) in smfi_setsymlist() so no macro is sent for the

selected stage.

 

MAKEMAP: A change to check TrustedUser in fewer cases which was

made in 2013 caused a potential regression when makemap

was run as root (which should not be done anyway).

 

Note: sendmail often contains options "For Future Releases"

(prefix _FFR_) which might be enabled in a subsequent

version or might simply be removed as they turned out not

to be really useful.  These features are usually not

documented but if they are, then the required (FFR)

options are listed in

- doc/op/op.* for rulesets and macros,

- cf/README for mc/cf options.
