Profitability Calculator v0.6.5beta

• Made it possible to sync up custom coins with a coin daemon/wallet-qt, if it supports "getmininginfo" through JSON-RPC
• Doubleclick a result now and get loads more info about order depths on the supported exchanges and other detailed info.
• Added option to use 24hr diff, if available (CoinWarz doesn't supply this). If not, it will use the current diff from that source.
• Cleaned up the Price Calc settings (you may lose some saved settings here)
• Made it possible to use the "fallthrough" price, the price you'd get if you were to dump all your coins on an exchange, to find out what exchange is the most stable.
• Added a bar in the middle to resize the settings & the results table.
• Several bugfixes.

Profitability Calculator v0.6beta

• Rewrote most off the code behind hashrates, and made it a lot more customizable. Now you can add new mining algorithms yourself in a flexible way.
• Added custom coins. If one of the coin info APIs don't support your coin yet, add it yourself.
• Added C-Cex, Comkort, BTer, Atomic Trade & Cryptoine to the supported exchange APIs.
• Added profiles. This is not used by myself, so beware, not fully tested. Testers needed! :D
• Loads of other bug fixes and improvements, as usual.

Profitability Calculator v0.5.7beta

• Added support for cryp.today, a site maintained by suchmoon that shows the payout he truly got for different multipools (comparing with PoolPicker results may be skewed if one updates at different times than the other)
• Added a log screen, no more annoying popup screens
• Error counter in bottom-right corner so you know when to check the log ;-)
• Live-filtering of the table based upon settings in "Coin Price Calc"
• Rainbow colored option under "Misc settings" :D
• Updated to Bittrex V1.1 API. Old version goes down on the 20th of July.
• Again, some general speedups, bugfixes and improvements

Profitability Calculator v0.5.5beta

Intermediary release, not everything is 100% as I want it (still so much to add :D )

• Another rework of the GUI, opens up a lot of space.
• Added X15 & Qubit
• Added support for Nicehash X15 & Nist5
• Added proxy support (no idea why, but I just could)
• Added option that lets you switch between highest buy, most recent trade or lowest ask for price calc
• Added option to ignore coins with negative profit
• Added option to weigh PoolPicker ratings into the price (rating % * price), gives a more honest view IMO
• Some general speedups, bugfixes and improvements

Profitability Calculator v0.5beta

• Added CryptoNight support + uses MoneroChain api to get diff and blockreward
• Added electricity cost into the calculation
• Moved the layout a bit around
  -- Hashrates to the side + checkboxes for each algo
  -- Checked listbox for all market apis

• Some other small fixes and improvements

Profitability Calculator v0.4.1beta

I always seem to forget something ^^" Well spotted, yellowduck2!

Profitability Calculator v0.3.1beta

Small fix to make it exclude very low volume coins when "healthy coins" is checked. Charitycoin could've given me 12BTC/day if it didn't had only 0.088BTC of daily volume :D

Profitability Calculator v0.4beta

• Added fiat/day option (USD, EUR, GBP & CNY)
• Massive speed upgrade ( :P )
• General optimizations.

Profitability Calculator v0.3beta

• Added Poloniex
• Added option to weigh all exchanges into the BTC price, like this:
  (exchange1_price * exchange1_percentageOfTotalVol) + (exchange2_price * exchange2_percentageOfTotalVol) + ...
  Gives a better view on the real price if a coin is well spread among exchanges.
• Fixed PoolPicker
• General improvements and fixes
