      [b]Feathercoin - The Miner Update - Hard Fork Block 87948[/b]

      The latest Feathercoin version 0.6.4.4 is now available and is a mandatory update. This update includes a hard fork of the block chain to accommodate the changes made in this patch. This hard fork should happen roughly around the 1st October which is only a week away. To be able to send and receive Feathercoin after block 87948 you have to use the new client. Continuing to use old clients after the hard fork could result in the loss of coins.

      Primarily this update is to further the refine of the difficulty adjust. Though the current Feathercoin difficulty which we changed to get us out of a tough spot it is not fair for long term miners who have to experience 41.4% swings on every adjust. The new code will adjust four times more frequently at 126 blocks but to approximately 9% which still gives the exact same overall adjust. To prevent the difficulty from being sent up or down too rapidly the current 504 sample window is being maintained and damping is being introduced to reduce fluctuations between extremes.

      There have been long running discussion and arguments on the Feathercoin forum including simulations of various different options surrounding this solution. Feel free to take a look at the latest discussion [url=https://forum.feathercoin.com/index.php?topic=3447.0]here[/url].

      To get the latest update please go to the Official Feathercoin Website and download the client from the homepage.

      [url=https://www.feathercoin.com]Official Feathercoin Website[/url]

      Changelog:
      Move to 126 difficulty adjust with 504 averaging window and .25 damping
      Reduce effectivness of Time Warp attack
      Reinstate CAlert system
      Make getnetworkhashps more accurate
      Release Windows binary with QR encode

        Edit: Turns out it’s a .exe now :), just install it over your existing installation!

              That file should be created as part of the compilation process.

              Can you give us a run down of what you are doing, where it is going wrong and provided some error text?

                I encountered this while compiling…

                /FeatherCoin/src/obj -DUSE_UPNP=0 -DHAVE_BUILD_INFO -fno-stack-protector -fstack-protector-all -Wstack-protector -D_FORTIFY_SOURCE=2 -MMD -MF obj/net.d -o obj/net.o net.cpp
                net.cpp:21:32: fatal error: miniupnpc/miniwget.h: No such file or directory
                compilation terminated.
                make: *** [obj/net.o] Error 1

                miniupnpc is installed, running on mint 15.

                Update, found the solution…

                I install the following…

                sudo apt-get install libminiupnpc-dev

                Compiled 6.4.4 feathercoind without issue.

                Thanks… :)

                Note: its not in the build-unix.txt to install the “libminiupnpc-dev”. Maybe its good to update the build-unix.txt in the document folder.

                  Thanks for the feedback and well done for figuring it out. I have added that to the docs in the new Qt testbuild.

                  Quick fix for that is changing USE_UPNP:=0 to USE_UPNP:= in the makefile.unix file but then you have no UPNP functionality.

                                It looks like I will be asleep when it happens, I have kids to take to school in the morning. I have given my mobile number to several people in case of an emergency.

                                The new stats page is up which looks just like the old one but works on adjusts every 126 blocks.

                                        Hi I’ve just been thinking about this and would it be possible to have some kind of indicator that a client is out of date? Even some kind of RSS feed from feathercoin.com that is checked daily by the client and shows any new messages. Maybe this should be a new thread? Kris

                                          Good news. With this client update we reinstated the CAlert system. This allows us to send messages to specific versions of the client with the message to upgrade. Whenever we come to hard fork in the future we can use this system. We can also tell people to downgrade in case of an emergency.
