    This development dispatch covers work completed since the Decred v0.0.5 release from February 26th, 2016. Since then, developers have merged 35 pull requests of code into 4 software repositories. During this period, a total of 96 commits occurred in these (and newly covered) repositories and represent modifications to the effect of 20,650 lines of code added to and 10,668 lines removed from the codebase. Included in the new repositories covered is Paymetheus - a native Windows wallet GUI for Decred. Finally, 2 requests for proposals (RFP) were closed and consultation with new developers is in progress to begin work on these deliverables (RFP-1 and RFP-5). A total of 3 RFPs remain open.

    Great update! Decred is progressing nicely.

    An idea for dcrwallet: getSStxAveragePrice --> --ticketmaxprice=getSStxAveragePrice

    This usage would smooth out volatility in SStx prices if it were widely used. Good idea? Possible? @ay-p, @ceejep, @chappjc, @jcv, @jrick

    I'm running v0.0.5 on aws, successfully and smoothly stake mining. Do I need to update if I'm happy with how things are running now? In either case, how should one go about performing the update without interfering with staked tickets? I'm thinking:
    1. Shut down running instances of dcrd and wallet.
    2. Move files to "old" folder.
    3. Download new versions.
    4. Start up, executing same commands as prior for stake mining.

    Let me know if this procedure seems appropriate? I'm assuming the new files will know my wallet address, ticket status, etc. automatically. If not, would I just restore wallet from seed in the new wallet?

    Thank you for the support and another considerable update!

    Yeah that works for me. To keep down time as little as possible, i either use .bat or enter all necessary commands and then execute them one by one after shutting down old command windows using ctrl+C. takes less than 30 seconds.

    All your data is in appdata/local/dcrd & appdata/local/dcrwallet folders so new exe will find it w/o problem. It has nothing to do with old exe files.

    I do not see a "wallet backup" mentioned, beware !

    Let me preface this with the fact that I am not an expert. If we keep the seed offline and redundantly secured, then why would we need a wallet backup feature? Isn't that sufficient?

    I am not sure about that, that might keep your addresses intact but people had missing tickets until they copied the wallet file itself.

    Can't we just copy the APPDATA Dcrwallet folder to a backup drive then? Then just copy paste and restore, if necessary?

    Dcrd and Dcrwallet folders from appdata,
    I copied it to another machine starting PoS mining,
    everything worked smooth, not a problem. :)
