Version 0.2.0

Changelog

Backend

• Changed database engine from SQLite to PostgreSQL. Providing faster query performance, better support for concurrency, and further options for scalability.
• Removed usernames and contacts from mainchain (to be later reimplemented as a separate Identity Dapp sidechain). Delegate usernames still remain.
• Added dapp zip link storage mechanism, replaces GitHub and Sia integration, with alternative decentralized solutions to be implemented in future releases.
• Implemented concatenated inserts/updates, dramatically reducing number of round trips between client and database: https://github.com/vitaly-t/pg-promise/wiki/Performance-Boost
• Implemented promise based database logic using: https://github.com/vitaly-t/pg-promise
• Added optional PostgreSQL event monitoring using: https://github.com/vitaly-t/pg-monitor (see: config.json:db.logEvents). This will be used for finding further efficiency improvements at the database level.
• Enabled gzip compression on all http requests using: https://github.com/expressjs/compression. Significantly reducing the size of payloads transmitted between peers on the network, and also for lisk-ui (Example: vendor_app.js : Without compression 5.4MB, With compression: 1.2MB).
• Improved syncing reliability and chain comparison efficiency between peers, through query and code refactoring of Blocks#getIdSequence and the /peer/blocks/common API endpoint.
• Accounts#getDelegate(s): Calculating approval rating from total supply rather than a static amount.
• Increased max transactions per block from 10 to 25 (subject to further change after more testing and efficiency improvements have been made).
• Changed peers communication format from CSV to JSON.
• Fixed DApps#getInstalledIds, filtering installed ids to only include numerically named folders.
• Fixed "Dapp not ready" messages when auto-launching dapps upon starting client.
• Closed #24. Changing 'sync' to 'syncing'. @HeisenbergCoin
• Closed #33. Logging each client request. @slasheks
• Fixed #36. Adding username and publicKey properties. @fix
• Fixed #47. Changing timestamps to UTC. @TheGoldenEye
• Fixed #50. Indicating forged blocks more clearly. @punkrock
