v0.4.9 - Patch Release

MANDATORY PATCH RELEASE BEFORE BLOCK 400 000.

This release adds some additional transaction security to reduce the impact of TX flood attacks.

• limits the total number of outputs allowed
• limits the total number of fusion transactions allowed in the mempool
• removes invalid traansactions from the mempool

v0.4.8

Upgrade to this release is required

Network Upgrade at block 400,000

Full Node Resync May Be Required

This release contains 2 fixes to the way that data is serialized/deserialzed. The fixes are necessary for the proper operation of Plenteumd; however, the fix may reveal data corruption in your local copy of the blockchain (both the database and underlying local cache). Unfortunately, the only way to resolve the data corruption is purge the corrupted data and resync from that point or perform a full resync.

If you encounter a message stating that your local blockchain cache is corrupted, please try the directions given (be patient, it may take a while).
Or, you may resync your node from scratch.

Checkpoints

To help speed up your sync, please use checkpoints.

Plenteumd Default Settings Change

The default database write buffer size, read buffer size, maximum open files, and background threads have decreased to help with daemon stability. The decreases are as follows:

Write Buffer Size: 1GB -> 256MB
Read Buffer Size: 1GB -> 128MB
Maximum Open Files: 500 -> 125
Background Threads: 10 -> 4
These values may need adjusted based on your system resources, configured limits, etc. Please review the Plenteumd --help for changing these values at runtime.
We recommend that pool and other service operators run with higher values for the best performance.

v0.4.5

Special Notes

Please note, the build directions have changed, refer to the main Readme for instructions.

Upgrade to this release is required

Network Upgrade at Block 280,000

The v0.4.5 release of the core Plenteum software activates a network upgrade at block 280,000 that includes the following:

• changed the difficulty algorithm parameters to allow for much faster network hashrate updates when large volumes of hash rate join or leave the network.
• forces the verification of the signature counts on transactions send throughout the network.
• helps reduce the risk of blockchain bloat from malformed transactions.
• restricts transaction extra to a maximum of 1,0240 bytes to prevent chain storage bloat.
• activates logic immediately that stops transactions exceeding this size limit from entering the transaction pool or being selected during the getblocktemplate calls; however, until block 280,000 transactions included in a block may still have transaction extra data exceeding the 1,0240 byte limit.

Pools, miners, and services can do their part by upgrading their daemons as soon as possible.

Release Notes

General Updates

• Implements fork at 280,000 to reject new transactions with TX_EXTRA data > 1,0240 bytes and to reject new transactions where the signature count is incorrect for the number of inputs in the transaction.

• Implements blockchain bloat protection from malformed transactions
• Renamed PAGE_SIZE parameter in slow-hash functions that was causing errors when building for some users

• Resolved issue in some OSX build environments where building with the latest Xcode failed
• Resolved an issue in the CMake build directions that were causing issues in a rare number of circumstances.
• Added fundamental SQLite3 support into the project
• Project now builds under MSVC 2019

v0.3.0 - Mandatory update before block 130, 000

This is a mandatory update to the core software including a PoW Algorithm change at block 130, 000. It's important that you update your software before this block height is reached.

You can read about the updates here: https://medium.com/@whassupza/introducing-plenteum-v0-3-0-338021614220

v0.2.3 - Mandatory Update before Block 67500

This release is an update to allow for larger transactions and block sizes from Block 67500. This is a mandatory update so please ensure you update your software before block 67500.

v0.2.2

Release includes 0 fees and first stage of dust extraction to the dust fund.

IMPORTANT NOTE: Due to the fact that it will take some time to get the entire network updated, and older nodes will still require a minimum transaction fee, we strongly recommend that you continue to send transactions with a minimum fee of 0.1 PLE to ensure those transactions are not rejected by older nodes.

Initial Release

First Official Release of Plenteum

** Do not use poolwallet ** - use zedwallet, GUI (for windows users) for personal wallets, or service for rpc wallet

** A Note about the GUI - if you are having trouble connecting to the service using the remote nodes, we suggest you run a local instance of Plenteumd and then start up the wallet once it is sync'd.

Special Thanks to discord community Hero & moderator Charlie for the Linux binaries - compiled for ubuntu 16
note** if you're running 18 and having issues with zedwallet & libreadline, please see Charlie's mining guide which has some additional info on how to deploy these binaries to Ubuntu 18.
And another huge thank you to discord community member JerMe404 for the OSX binaries...
