+  * sctp, udplite support for the hash:*port* types
+- ipset-genl: handle EAGAIN return value emitted from autoloader
+- ipset-genl: resolve nfgenmsg remains and fix spurious protocol abort
+
+
+v1.34 (2011-04-07)
+==================
+Fixes:
+- xt_pknock: avoid crash when hash TFM could not be allocated
+- xt_pknock: avoid inversion of rule lookup that led to warnings
+- xt_DNETMAP: add missing module alias
+- xt_DNETMAP: support for kernels below 2.6.34
+Changes:
+- Linux kernel versions below 2.6.29 are no longer officially
+  supported, and will not be part of compilation testing.
+  Expect that compat code will be removed shortly.
+
+
+v1.33 (2011-02-02)
+==================
+Fixes:
+- build: restore functionality of `configure --without-kbuild`
+- build: fix objdir builds for ipset-5 (xt-a specific)
+- build: fix missing inclusion of dependency rules
+- xt_LOGMARK: fix detection of untracked connection for Linux >= 2.6.36
+Enhancements:
+- IPv6 support for xt_geoip
+- Update to ipset 5.3
+  * make IPv4 and IPv6 address handling similar
+  * show correct line numbers in restore output for parser errors
+- Update to ipset 5.4
+  * fixed ICMP and ICMPv6 handling
+  * fixed trailing whitespaces and pr_* messages
+  * fixed module loading at create/header commands
+- build: support for Linux up to 2.6.38
+- build: preliminary support for iptables 1.4.11
+
+
+v1.32 (2011-01-04)
+==================
+Fixes:
+- Update to ipset 4.5
+  * the iptreemap type used wrong gfp flags when deleting entries
+- Include ipset 5.2 with genetlink patch (beta)
+  * no kernel patch needed, but requires Linux >= 2.6.35
+    and thus needs to be manually enabled in mconfig
+
+
+v1.31 (2010-11-05)
+==================
+Fixes:
+- build: improve detection of kernel version and error handling
+Changes:
+- build: automatically derive Xtables module directory, thus
+  --with-xtlibdir is no longer needed for ./configure in most cases
+  (If I still see a distro using it, I will scold you for not
+  reading this changelog.)
+Enhancements:
+- LOGMARK: print remaining lifetime of cts
+- xt_iface: allow matching against incoming/outgoing interface
+- libxt_gradm: match packets based on status of grsecurity RBAC
+  (userspace part only - xt_gradm is in the grsec patch)
+
+
+v1.30 (2010-010-02)
+===================
+Fixes:
+- update to ipset 4.4
+  * ipport{,ip,net}hash did not work with mixed "src" and "dst"
+    destination parameters
+Changes:
+- deactivate building xt_TEE and xt_CHECKSUM by default, as these have been
+  merged upstream in Linux 2.6.35 and 2.6.36, respectively.
+  Distros still wishing to build this need to enable it in their build
+  script, e.g. perl -i -pe 's{^build_TEE=.*}{build_TEE=m}' mconfig;
+
+
+v1.29 (2010-09-29)
+==================
+- compat_xtables: return bool for match_check and target_check in 2.6.23..34
+- ipset: enable building of ip_set_ipport{ip,net}hash.ko
+- support for Linux 2.6.36
+- SYSRQ: resolve compile error with Linux 2.6.36
+- TEE: resolve compile error with Linux 2.6.36
+- add workaround for broken linux-glibc-devel 2.6.34 userspace headers
+  ("implicit declaration of function 'ALIGN'")
+
+
+v1.28 (2010-07-24)
+==================
+- RAWNAT: IPv6 variants erroneously rejected masks /33-/128
+- new target xt_CHECKSUM
+- xt_length2: add support for IPv6 jumbograms
+- xt_geoip: fix possible out-of-bounds access
+- import xt_geoip database scripts
+
+
+v1.27 (2010-05-16)
+==================
+- further updates for the upcoming 2.6.35 changes

+This is the ipset source tree. Follow the next steps to install ipset.
+If you upgrade from an earlier 5.x release, please read the UPGRADE
+instructions too.
+
+0. You need the source tree of your kernel (version >= 2.6.34)
+   and it have to be configured with ip6tables support enabled,
+   modules compiled. Please apply the netlink.patch against your kernel
+   tree, which adds the new subsystem identifier for ipset.
+
+   Recompile and install the patched kernel and its modules. Please note,
+   you have to run the patched kernel for ipset to work.
+
+   The ipset source code depends on the libmnl library so the library
+   must be installed. You can download the libmnl library from
+
+	git://git.netfilter.org/libmnl.git
+
+1. Initialize the compiling environment for ipset. The packages automake,
+   autoconf and libtool are required.
+
+   % ./autogen.sh
+
+2. Run `./configure` and then compile the ipset binary and the kernel
+   modules.
+
+   Configure parameters can be used to to override the default path
+   to the kernel source tree (/lib/modules/`uname -r`/build),
+   the maximum number of sets (256), the default hash sizes (1024).
+   See `./configure --help`.
+
+   % ./configure
+   % make
+   % make modules
+
+3. Install the binary and the kernel modules
+
+   # make install
+   # make modules_install
+
+   After installing the modules, you can run the testsuite as well.
+   Please note, several assumptions must be met for the testsuite:
+
+	- no sets defined
+	- iptables/ip6tables rules are not set up
+	- the destination for kernel logs is /var/log/kern.log
+	- the networks 10.255.255.0/24 and 1002:1002:1002:1002::/64
+	  are not in use
+	- sendip utility is installed
+
+   # make tests
+
+4. Cleanup the source tree
+
+   % make clean
+   % make modules_clean
+
+That's it! 
+
+Read the ipset(8) and iptables(8), ip6tables(8) manpages on how to use
+ipset and its match and target from iptables.
+
+Compatibilities and incompatibilities:
+
+- The ipset 6.x userspace utility contains a backward compatibility
+  interface to support the commandline syntax of ipset 4.x.
+  The commandline syntax of ipset 6.x is fully compatible with 5.x.
+- The ipset 6.x userspace utility can't talk to the kernel part of ipset 5.x
+  or 4.x.
+- The ipset 6.x kernel part can't talk to the userspace utility from
+  ipset 5.x or 4.x.
+- The ipset 6.x kernel part can work together with the set match and SET
+  target from iptables 1.4.7 and below, however if you need the IPv6 support
+  from ipset 6.x, then you have to use iptables 1.4.8 or above.
+
+The ipset 6.x can interpret the commandline syntax of ipset 4.x, however
+some internal changes mean different behaviour:
+
+- The "--matchunset" flag for the macipmap type is ignored and not used
+  anymore.
+- The "--probes" and "--resize" parameters of the hash types are ignored
+  and not used anymore.
+- The "--from", "--to" and "--network" parameters of the ipporthash,
+  ipportiphash and ipportnethash types are ignored and not used anymore.
+- The hash types are not resized when new entries are added by the SET
+  target. If you use a set together with the SET target, create it with
+  the proper size because it won't be resized automatically.
+- The iptree, iptreemap types are not implemented in ipset 6.x. The types
+  are automatically substituted with the hash:ip type.
