HEAT 2.5.0 FULL CLIENT - WINDOWS & LINUX
Hard fork set for block 1,245,000
which is somewhere around next Friday (April 6th).
HEAT WALLET 2.5.0
This desktop wallet release embeds the 2.5.0 server version which is a mandatory update. If your wallet does not use the built in server (default behavior of the wallet is to connect to a remote API node) you could still use that but you'll lack the client side (UI) improvements.
Windows and Linux versions.
Mac OS version will follow.
Apart from the all important embedded server update this release contains dozens of fixes and improvements among some of the more notable are:
- Visual warning when sending to non existing accounts
- Visual warning when sending to accounts without public key
- Correct display of virtual balance in account explorer (virtual balance includes trades based on unconfirmed transactions)
- Asset Exchange websocket order books updates got fixed, updates as well when no new order is added but just on trades
- You can switch to beta network from the about dialog now (beta net toolbar color is red) (for developers and beta net testers)
- Recipient auto complete includes all numeric account ids now
This is a mandatory update, all nodes on the network need to run this version or higher.
Nodes below 2.4.0 will automatically be blacklisted by this version.
Nodes on 2.4.0 will remain working untill we reach block 1,245,000 as of when
a hardfork will take place.
This version will perform a one time scan of the blockchain on startup.
To install and run heatledger you need Java JDK 1.8 or higher installed, note that
JDK is different from standard java distributions.
On ubuntu we use sudo apt-get install default-jdk package. For other platforms
please look here http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
For configuration settings see the conf/heat-default.properties files in the installation folder.
## Whats in this release
### No more forks
First and foremost this release fixes the occasional forks that occurred and which
required node operators to do the regular rescans of the blockchain. Those rescans
are not needed anymore as HEAT is now considered stable.
### Stable Storage Engine
HEAT is different from other crypto currencies because of its special custom
build storage engine. Our unique storage engine is what allows us to scale in
size and speed. Building this engine however proved more difficult than
using a one size fits all - off-the shelf - storage engine like every other
crypto out there.
Our hard work however paid off which leads us to this stable and mature 2.5.0
This version supports benchmark mode which allows you to participate in the
upcoming HEAT Benchmark Competition. Instructions for this will follow but
participating requires at the very least that you run a HEAT server. Once you
run a HEAT server on main net it will be easy to run a second HEAT server
on the same machine but on benchmark net.
### High Speed Binary API
We are moving away from JSON as a transport mechanism and are instead adopting
the binary AVRO encoding from HADOOP. One of the parts that makes it possible
to run a benchmark server which does many thousands of transactions a second
over the internet is the use of binary data over websockets.
This version has that new RPC mechanism to which you can talk from your browser,
mobile or NodeJS app. Interfacing with HEAT is made possible through our
officially supported HEAT-SDK https://www.npmjs.com/package/heat-sdk.
### Adjustable Fees (spam protection)
Transaction fees can be remotely raised or lowered by the developers without the
need to update the software. An incubation period of 24 hours is observed before
the new fees take affect. This allows us to already lower the fees and raise
them again in case of misuse.
This is a temporary measure. Once block file splitting is enabled we dont care
about this anymore since the chain can grow indefinitely from then on.
We will start lowering the fees after the hard fork.
### Mem Pool Fixes
While technically a part of the storage engine, it is worth mentioning that the
unconfirmed transaction pool had a bug fixed which caused unconfirmed transactions
to be improperly rolled back. Leading to forks due to balance differences between
### Adjust heat.maxApiRecords
Use this setting to raise the number of rows returned from the various API's.
### Virtual Order Matcher
This is enabled again by default, the virtual matcher matches orders and generates
trades in real-time based on unconfirmed transactions.
### Numeric Account Ids
Numeric account ids are included in account search and in every autocomplete
now when sending transactions.
