+
+  ++ Bug fixes:
+  
+  * Fixed pool pbuf memory leak in pbuf_alloc().

+    Reported by Savin Zlobec.
+
+  * PBUF_POOL chains had their tot_len field not set for non-first

+  ++ New features:
+
+  * Added PPP stack contributed by Marc Boucher
+
+  ++ Changes:
+  
+  * Now drops short packets for ICMP/UDP/TCP protocols. More robust.
+
+  * ARP queueuing now queues the latest packet instead of the first.

+  ++ Bugfixes:
+
+  * TCP has been fixed to deal with the new use of the pbuf->ref

+
+  * DHCP dhcp_inform() crash bug fixed.
+
+  ++ Changes:
+
+  * Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
+    pbuf_refresh(). This has sped up pbuf pool operations considerably.
+    Implemented by David Haas.

+(0.6.1)
+
+  ++ New features:
+
+  * The packet buffer implementation has been enhanced to support
+    zero-copy and copy-on-demand for packet buffers which have their
+    payloads in application-managed memory.
+    Implemented by David Haas.
+
+    Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
+    if an outgoing packet can be directly sent on the link, or perform
+    a copy-on-demand when necessary.
+
+    The application can safely assume the packet is sent, and the RAM
+    is available to the application directly after calling udp_send()
+    or similar function.
+
+  ++ Bugfixes:
+
+  * ARP_QUEUEING should now correctly work for all cases, including
+    PBUF_REF.
+    Implemented by Leon Woestenberg.
+
+  ++ Changes:
+
+  * IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
+    to a '0.0.0.0' IP address.
+
+  * The packet buffer implementation is changed. The pbuf->ref counter
+    meaning has changed, and several pbuf functions have been
+    adapted accordingly.
+
+  * netif drivers have to be changed to set the hardware address length field
+    that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).

+1 Introduction
+
+This document describes some guidelines for people participating
+in lwIP development.
+
+2 How to contribute to lwIP
+
+Here is a short list of suggestions to anybody working with lwIP and 
+trying to contribute bugreports, fixes, enhancements, platform ports etc.
+First of all as you may already know lwIP is a volunteer project so feedback
+to fixes or questions might often come late. Hopefully the bug and patch tracking 
+features of Savannah help us not lose users' input.
+
+2.1 Source code style:
+
+1. do not use tabs.
+2. identation is two spaces per level.
+3. end debug messages with a trailing newline (\n).
+4. one space between keyword and opening bracket.
+5. no space between function and opening bracket.
+6. one space and no newline before opening curly braces of a block.
+7. spaces surrounding assignment and comparisons.
+8. use current source code style as further reference.
+
+2.2 Source code documentation style:
+
+1. JavaDoc compliant and Doxygen compatible.
+2. Function documentation above functions in .c files, not .h files.
+   (This forces you to synchronize documentation and behaviour.)
+3. Use current documentation style as further reference.
+ 
+2.3 Bug reports and patches:
+
+1. Make sure you are reporting bugs or send patches against the latest
+   sources. (From the latest release and/or the current CVS sources.)
+2. If you think you found a bug make sure it's not already filed in the
+   bugtracker at Savannah.
+3. If you have a fix put the patch on Savannah. If it is a patch that affects
+   both core and arch specific stuff please separate them so that the core can
+   be applied separately while leaving the other patch 'open'. The prefered way
+   is to NOT touch archs you can't test and let maintainers take care of them.
+   This is a good way to see if they are used at all - the same goes for unix
+   netifs except tapif.
+4. Do not file a bug and post a fix to it to the patch area. Either a bug report
+   or a patch will be enough.
+   If you correct an existing bug then attach the patch to the bug rather than creating a new entry in the patch area.
+5. Trivial patches (compiler warning, indentation and spelling fixes or anything obvious which takes a line or two)
+   can go to the lwip-users list. This is still the fastest way of interaction and the list is not so crowded
+   as to allow for loss of fixes. Putting bugs on Savannah and subsequently closing them is too much an overhead
+   for reporting a compiler warning fix.
+6. Patches should be specific to a single change or to related changes.Do not mix bugfixes with spelling and other
+   trivial fixes unless the bugfix is trivial too.Do not reorganize code and rename identifiers in the same patch you
+   change behaviour if not necessary.A patch is easier to read and understand if it's to the point and short than
+   if it's not to the point and long :) so the chances for it to be applied are greater. 
+
+2.4 Platform porters:
+
+1. If you've ported lwIP to a platform (an OS, a uC/processor or a combination of these) and you think it
+   could benefit others[1] you might want to post an url to a tarball or zip from which it can be imported 
+   to the contrib CVS module. Then you get CVS access and have to maintain your port :)
+
+[1] - lwIP CVS should not be just a place to keep your port so you don't have to set up your own CVS :)
+Especially welcome are ports to common enough OS/hardware that others can have access too.

+
+1 Anonymous CVS checkouts and updates
+-------------------------------------
+
+Obtain lwIP from the STABLE tree (on the CVS main trunk)
+
+cvs -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/lwip login
+cvs -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/lwip checkout lwip

+cvs -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/lwip login
+cvs -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/lwip checkout -r STABLE-0_6_3 -d lwip-0.6.3 lwip
+
+Or, obtain a development branch as follows:
+
+cvs -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/lwip login
+cvs -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/lwip checkout -r DEVEL -d lwip-devel lwip
+
+
+3 Merging from DEVEL branch to main trunk (stable branch)
+---------------------------------------------------------
+
+Merging from DEVEL to main requires that the DEVEL branch
+has a tag indicating the previous merger. This tag is
+called 'merged_from_DEVEL_to_main'.
+
+IMPORTANT: AFTER COMMITTING A SUCCESFUL MERGE IN THE
+REPOSITORY, THE TAG MUST BE SET ON THE SOURCE OF THE
+MERGE BRANCH (REPLACING EXISTING TAGS WITH THE SAME NAME).
+
+Merge all changes in DEVEL since our last merge to main:
+
+In the working copy of the main trunk:
+cvs update -P -jmerged_from_DEVEL_to_main -jDEVEL 
+
+Now move the tag in the DEVEL branch to this merge point,
+so we can use this for future merges.
+
+cvs -z4 rtag -F -r DEVEL merged_from_DEVEL_to_main lwip 
+
+4 How to release lwIP
+---------------------
+
+First, checkout a clean copy of the branch to be released. Tag this set with
+tag name "STABLE-0_6_3". (I use release number 0.6.3 throughout this example).
+
+Login CVS using pserver authentication, then export a clean copy of the
+tagged tree. Export is similar to a checkout, except that the CVS metadata
+is not created locally. 
+
+cvs -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/lwip login
+cvs -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/lwip export -r STABLE-0_6_3 -d lwip-0.6.3 lwip
+
+Archive this directory using tar.
+
+tar czvf lwip-0.6.3.tar.gz lwip-0.6.3
+
+First, make a local release directory to work in, I use "lwip-releases":
+
+mkdir lwip-releases
+cd lwip-releases
+
+Now, make a new release by creating a new directory for it (these are
+Savannah conventions so that it shows up in the Files list real nice):
+
+mkdir stable.pkg
+cd stable.pkg
+mkdir 0.6.3
+cd 0.6.3
+
+We can now copy the tar archive we made earlier into the release directory:
+
+cp /../../../lwip-0.6.3.tar.gz .
+
+Finally, synchronize this directory upwards to Savannah:
+
+rsync -n -e "ssh -1" -t -u -v -r . likewise@savannah.nongnu.org:/upload/lwip
+
+This does a "dry run": no files are modified! After you have confirmed that
+this is what you intended to do, remove "-n" and actually synchronize for
+real. The release should now be available here:
+
+http://savannah.nongnu.org/files/?group=lwip
+
+---
+Explanation of rsync options used:
+
+-t: preserve file timestamps
+-u: do not overwrite existing files, unless they are older
+-v: be verbose (long format file attributes)
+-r: recurse into directories
+-n: dry-run, do not modify anything. 
+---
+
+Additionally, you may post a news item on Savannah, like this:
+
+A new 0.6.3 release is now available here:
+http://savannah.nongnu.org/files/?group=lwip&highlight=0.6.3
+
+You will have to submit this via the user News interface, then approve
+this via the Administrator News interface.

-lwIP for Win32
-
-***WARNING***
-The current CVS code of this port isn't much tested.
-***WARNING***
-
-This is a quickly hacked port and example project of the lwIP library to
-Win32/MSVC.
-
-Due to the nature of the lwip library you have to copy this whole project
-into a new subdir in proj and modify lwipopts.h to your needs. If you move
-it to another directory besides proj, you have to update the include paths
-in the project settings.
-
-Included in the proj/msvc6 directory is the network interface driver using
-the winpcap library.
-
-There is no more documentation yet. Try to figure it out yourself.
-
-This is provided as is, it's just a hack to test some stuff, no serious
-implementation.

-This directory contains an example of how to compile lwIP as a self
-initialising shared library on Linux.
-
-Some brief instructions:
- 
-* Compile the code:
-
- > make clean all
-
- This should produce liblwip4unixlib.so.  This is the shared library.
-
-* Link an application against the shared library
-
- If you're using gcc you can do this by including -llwip4unixlib in
-your link command. 
-
-* Run your application
- 
- Ensure that LD_LIBRARY_PATH includes the directory that contains
-liblwip4unixlib.so (ie. this directory)
-
-
-
-If you are unsure about shared libraries and libraries on linux in
-general, you might find this HOWTO useful:

-This directory contains an example of how a project using lwIP might
-look. It is also the development platform of lwIP, since it can be run
-as a user process under FreeBSD or Linux. There are also a number of
-example applications (including a simple web server) in the apps/
-directory.
-
-Some short instructions on how to build and run lwIP on a FreeBSD or
-Linux host. For FreeBSD, the tap interface must be enabled in the
-kernel configuration and the kernel must be recompiled. The tap
-interface is enabled by adding the line "pseudo-device tap" in the
-kernel configuration. See Chapter 9 in the FreeBSD handbook for
-instructions on how to build a custom FreeBSD kernel.
-
-* Compile the code. This must be done by using GNU Make. Under
-  FreeBSD, GNU Make can be found in the ports collection under
-  /usr/ports/devel/gmake (type "make install distclean" to
-  install). Under Linux, GNU Make is the default "make".
-
-  > gmake         (FreeBSD)
-
-  > make          (Linux)
-
-* The compilation process produces the executable file "simhost". To
-  run this, you have to be root.
-
-  > su            (Type password for the root account)
-  # ./simhost
-
-* The lwIP TCP/IP stack is now running with IP address
-  192.168.0.2. Some things that you can try:
-
-  To see the packets that are going to and from the lwIP stack, run
-  tcpdump:
-
-  # tcpdump -l -n -i tap0
-
-  You can ping lwIP:
-
-  > ping 192.168.0.2
-
-  For a telnet shell, run:
-
-  > telnet 192.168.0.2
-  
-  Finally, "simhost" also includes a simple web server; the URL is
-  of course http://192.168.0.2/.

-	  </p>
-	  <p>
-	    lwIP is an open source implementation of the TCP/IP
-	    protocol suite that was originally written by Adam Dunkels
-	    of the Swedish Institute of Computer Science but now is
-	    being actively developed by a team of developers
-	    distributed world-wide. Since it's release, lwIP has
-	    spurred a lot of interest and has been ported to several
-	    platforms and operating systems. lwIP can be used either
-	    with or without an underlying OS.
-	  </p>
-	  <p>
-	    The focus of the lwIP TCP/IP implementation is to reduce
-	    the RAM usage while still having a full scale TCP. This
-	    makes lwIP suitable for use in embedded systems with tens
-	    of kilobytes of free RAM and room for around 40 kilobytes
-	    of code ROM.
-	  </p>
-	  <p>
-	    More information about lwIP can be found at the lwIP

- * This is a device driver for the Crystal Semiconductor CS8900
- * chip in combination with the lwIP stack.
- *
- * This is work under development. Please coordinate changes

- *
- * A quick function roadmap:
- *
- * cs8900_*() are low level, cs8900 hardware specific functions.
- * These are declared static in the device driver source and
- * SHOULD NOT need to be called from outside this source.
- *
- * cs8900if_*() are the lwIP network interface functions.
- * 
- * cs8900_interrupt() is an early interrupt service routine (ISR).
- * It merely sets a flag to indicate the cs8900 needs servicing.
- * (This function MAY be tied to an interrupt vector, IF present).
- *
- * cs8900_service() is the actual interrupt event service routine.
- * It must be called whenever the cs8900 needs servicing. It MAY
- * be polled safely (so, you do NOT NEED interrupt support.)
- *
- * cs8900_init() sets up the cs8900, using its register set. When
- * using the driver on your particular hardware platform, make sure
- * the register setups match.
- * Function is called from cs8900if_init().
- *
- * cs8900_input() transfers a received packet from the chip.
- * Function is called from cs8900if_input().
- *
- * cs8900_output() transfers a packet to the chip for transmission.
- * Function is called from cs8900if_output().
- *
- * cs8900if_init() initializes the lwIP network interface, and
- * calls cs8900_init() to initialize the hardware.
- * Function is called from lwIP.
- * 
- * cs8900if_service() is the service routine, which must be called
- * upon the need for service, or on a regular basis, in order to
- * service the Ethernet chip.
- *
- * cs8900if_input() calls cs8900_input() to get a received packet
- * and then forwards the packet to protocol(s) handler(s).
- * Function is called from cs8900_service().
- *
- * cs8900if_output() resolves the hardware address, then
- * calls cs8900_output() to transfer the packet.
- * Function is called from lwIP.
- *
- * Future development:
- * 
- * Split the generic Ethernet functionality (a lot of the
- * cs8900if_*() functions) and the actual cs8900a dependencies.
- *
- * Enhance the interrupt handler to service the Ethernet
- * chip (to decrease latency); support early packet
- * inspection (during reception) to early drop unwanted
- * packets, minimize chip buffer use and maximize throughput.
- *
- * Statistics gathering, currently under development.
- * SNMP support, currently under development.
