ROIcoin v1.1.6.000

ROIcoin Release Notes for v1.1.6.0

Since the availability of ROIcoin v1.1.5 , we have experienced an unexpected fork again.
This release is an emergency mandatory upgrade for all users ! it contains
a fix that takes immediate effect against the fork type we have seen so far.

This release overwrites all previous release, there will be a hard fork at block 75100 , at which
point all older releases <1.1.6 will be rejected and considered as obsolete.

As soon as you have upgraded, wait for your wallet to fully sync, if the block height does not match
our block explorer then you are on the wrong chain, I am providing a bootstrap file to resync in case you need it.
https://blockexplorer.roi-coin.com/
https://roi-coin-blockexplorer.roi-coin.com/

Procedure to resync the blockchain:
backup your wallet.dat , remove your blocks and chainstate subfolder from %APPDATA%/Roaming/ROIcoin folder and unzip ROIcoin-05142018-blockindex.zip , then restart the wallet. You can reach us on slack or discord if you need help.

ROIcoin v1.1.5.000

ROIcoin Release Notes for v1.1.5.0

This release is for pool, exchange operators and users with large wallets.
I strongly recommend everyone to upgrade as you will see a performance improvement and overall less cpu usage than v1.1.4

Optiminer found a significant performance optimization which affected the overall performance
of the wallet and most RPC calls.

Additionally I have added 2 new RPC calls, that will help online web providers and exchanges.

deposittoaddress "fromaccount" "ROIcoinAddress" Amount TermLengthInBlocks "comment" "comment-to" subtractFeeFromAmount_Flag.
Example:
deposittoaddress "gary" "RBQN9ybF5JzsPQdsiHMpGfkA5HpwddKvmU" 40 10800 "1week deposit" "pool earnings"

This call allows you to create a new Term Deposit using RPC/CLI and opens the door to automated scripts.
If you specify an empty string "" for fromaccount argument it will use your default account.

listtermdeposits "fromaccount"

This call allows you to list term deposits that belong to a specific account in your wallet , use "" for default.

Changes

• NEW- issue #10 added 2 new RPC calls , deposittoaddress and listtermdeposits
• BUG - issue #49 TheTDD PR merge to fix hash rate accuracy in solo miner
• BUG - Optiminer fix to getPostRateForAmount() function doing too many math.pow() calls affecting performance on large wallets and slower cpu's.

ROIcoin core v1.1.5.0 is now available at:
https://github.com/ROIcoin/ROIcoin/releases/

Please report bugs using the issue tracker at github, we will not use bitcointalk forum for handling bug reports.

ROIcoin v1.1.4.000

ROIcoin Release Notes for v1.1.4.0

Important Notice:

We still see many users using old obsolete wallets, for this reason there will be a hard fork at block 75000.
IF you are on the wrong chain ( not the same height as the block explorer ) , you will need to re-sync, this will be faster with v1.1.4, thanks to the fix for issue #47

The biggest new feature is the faster block loading times. The first time you start the new wallet it will still take as long as before, because it is building up a new hash index database ( You will see a new sub folder called "cache" in the blocks folder ).
Warning: You must let the loading process complete
The second time you restart the new wallet you will see a significantly faster loading time. This new cache only requires about 30 Mb extra disk space.

Changes

• NEW - issue #15 a new flag -autoban (default is off) was introduced to automaticaly ban peers for 24hrs if they returned "Connection Refused" or "Host unreachable".
  This will reduce the cpu load when handling peers. ( recommended for 24/7 servers and VPS )
• NEW - issue #16 a new flag -banobsoleteversion (default is off) was introduced to automaticaly ban peers for 24hrs who have obsolete old wallet version ( < v1.1.4 )
• NEW - issue #40 matured coins will now show an alert bubble ( just like when you find a new block )
• FIX - issue #39 TheTDD has rebuild the term deposit table from scratch and fixed the sorting issues ( should also be faster to sort and update ).
• NEW - issue #47 TheTDD has implemented a deposit table delay mechanism to slow down UI updates during block sync at startup.
  Note: On Startup, it can take up to 5s before you see your term deposits, but it will speed up block syncing.
• BUG - issue #19 the wallet rpcport was wrongly configured and conflicted with the p2p port, this was the reason for the slow syncing and low peer counts issues in the past.
  The rpcport is now by default set to 3376
• NEW - issue #22 the sending addressbook will now contain the send and receive addresses combined , this will facilitate sending matured coins or combining inputs to yourself.
• FIX - rpc gettransaction call will now show credit value without interest ( requested by elbandi, to help pool operators )
• FIX - issue #42 estimated date is now based on 120s blocktime , this should provide a more accurate "Estimated Date" value.
• FIX - issue #44 setban rpc command can now accept a custom bantime ( larger than 24hrs )

ROIcoin v1.1.3.000 Hotfix1

Release Notes Version 1.1.3 Hotfix1

Warning: You do not need to install this update if your blockchain height matches our blockexplorer.

This hotfix addresses a windows bug with fee calculation precision quirks. This fix was already part of our upcoming release.

If you are a Windows user please download ROIcoin-qt-v113-hotfix1.zip and update immediately. For your convenience we have included exhaustive directions in both Word document and PDF format. If you are a non Windows user and happen to be impacted by these events please submit the details of your issue at https://github.com/ROIcoin/ROIcoin/issues

Other changes

To help administrators out there I have added the following 3 new RPC calls,
These RPC calls are available both via ROIcoin-cli and the GUI debug window.

• setban ip or ip/netmask add/remove - manually add or remove a peer to ban list
• listbanned - list banned peers
• clearbanned - clears all banned

Note: banlist is persisted in banlist.dat file, so the server will remember on restart.

Example:

ROIcoin-cli setban 10.10.10.15 add
ROIcoin-cli listbanned
 [
   {
       “address” : “10.10.10.15/255.255.255.255",
       “banned_until” : 1514554316,
       “ban_created” : 1514467916,
       “ban_reason” : “manually added”
   }
 ]
 ROIcoin-cli getpeerinfo | grep 10.10.10.15
  gone !!

Note: This can also be helpful in temporarily banning peers who are on the wrong chain.
Warning: this is a PRE-RELEASE, I am still endurance testing it, its in use on our seed nodes.

ROIcoin v1.1.2.000

ROIcoin v1.1.2

Emergency Release

The previous critical bug fix in v1.1.1 created a consensus disagreement between 2 windows miners mining the same block, Miner1 was on v1.1.0 and Miner2 on v1.1.1, both had a different result when calculating fees. This caused a fork in our block chain at height 29732

To resolve this situation we are hard forking at block nr. 31000 to make sure all miners are on v1.1.2.

Checking your blockchain

In addition to mandatory upgrade, you may need to reindex your blockchain to the same chain our
exchanges and block explorer are using.

Go to Help->debug window-> console tab and type "getblockhash 29732"
if you see "0000006aef642158383b16bd16b67d762a41a63ae2cfbdc6479d65d229818175" then you
are on the correct chain, otherwise you need to:

• delete your blockchain folders named "blocks" and "chainstate" usually stored in c:\users<USER>\AppData\Roaming\ROIcoin and on linux in $HOME/.ROIcoin folder.
• download our bootstrap-27122017-chain-x175.zip file
• unzip it
• run ROIcoin-qt.exe -loadblock=c:\FULL-PATH-TO\bootstrap.dat

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions). Backup your wallet.dat file ( which you should always do regardless of an upgrade event ) then just copy over ROIcoin-qt.exe (win64) or ROIcoin-qt (linux).

ROIcoin v1.1.1.000

This release contains one critical and some minor fixes.

• issue #6 A variable initialisation bug in the interest rate calculation caused windows wallet to crash. (found by elbandi)
• issue #7 The windows miner stops after encountering a block validation error due to "too high fee". (caused by issue 6) We added a retry mechanism around runtime errors, the timeout is configurable via a new flag called "-minerblocktimeout" (default 30000 ms)

Other minor fixes:

• max outbound connections was increased from 8 to 16
• roicoin.icns was fixed for the MAC OSX wallet
• build instructions are now provided for MAC OSX, CentOS7 and Fedora27

Note: Both issues were only affecting windows users, but we still recommend all users to upgrade to v1.1.1

ROIcoin core v1.1.1.0 is now available at: https://github.com/ROIcoin/ROIcoin/releases/

ROIcoin v1.1.0.000

ROIcoin Release Notes for v1.1.0.000

This release contains one critical and some minor fixes.

• The critical fix is for the term deposit interest rate algorithm bug that kept increasing on every block.
• The new wallet will make sure that if you have pre-fork locked term deposits, the maturation interest will remain unchanged.
• New term deposits created after the hardfork will obey the new term deposit rates:

Time	Start Coins	End Coins	Coin Gain	Interest
1 week	1000	1021	21	2,10%
2 weeks	1000	1043	43	4,30%
1 month	1000	1096	96	9,60%
3 months	1000	1331	331	33,10%
6 months	1000	1929	929	92,90%
12 months	1000	6933	5933	593,30%

The PoS calculation has been adjusted to 15% APR

Note: the old HOdl per block 30 day interest still applies on top of ROI PoS rate.

We also applied cosmetic branding changes to the wallet splash screen and background.

Hardfork at block 25000

Notice to miners:

• If you are solo-mining you must upgrade to v1.1.0.0 before reaching block 25000 , any blocks found with the old wallet after the fork will be on the wrong chain !.
• If you are pool-mining make sure to check with the pool owner that their wallet has upgraded to v1.1.0.0 before block 25000
• Exchange owners please upgrade to v1.1.0.0 as soon as possible.
