XRP Ledger (rippled server) version 1.6.0 has been released. This release introduces several new features including changes to the XRP Ledger's consensus mechanism to make it even more robust in adverse conditions, as well as numerous bug fixes and optimizations. (This post has been updated with recommendations for upgrading.)
Ripple plans to upgrade the XRP Ledger Devnet to use a recommended validator list like the ones used on the Testnet and Mainnet. Ripple also plans to reset the Devnet history and state at this time. If you operate a server on the XRP Ledger Devnet, or run software on the Devnet, you must upgrade your configuration to remain synced.
As previously announced, the RequireFullyCanonicalSig amendment became enabled on the XRP Ledger on 2020-07-03. Additionally, the fixQualityUpperBound amendment became enabled on 2020-07-09 and the FlowCross amendment became enabled on 2020-08-04.
With these amendments enabled, version 1.5.0 is the minimum server version to remain synced to the XRP Ledger.
XRP Toolkit, developed by Towo Labs, is a platform for managing crypto assets on the XRP Ledger, including a full-featured graphical user-interface (GUI) for the XRP Ledger's built-in decentralized exchange (DEX).
The RequireFullyCanonicalSig amendment to the XRP Ledger, introduced in rippled v1.5.0, has gained support from a majority of trusted validators. Currently, it is expected to become enabled on 2020-07-03 (UTC). As long as the RequireFullyCanonicalSig amendment continues to have the support of at least 80% of trusted validators continuously, it will become enabled on the scheduled date.
As previously announced, the Checks amendment became enabled on the XRP Ledger on 2020-06-18.
The Checks amendment to the XRP Ledger, introduced all the way back in rippled v0.90.0, has gained support from a majority of trusted validators. Currently, it is expected to become enabled on 2020-06-18. As long as the Checks amendment continues to have the support of at least 80% of trusted validators continuously, it will become enabled on the scheduled date.
This week on Developer Reflections, we're proud to highlight Xrplorer, a powerful open analytics platform built on top of a graph database representation of the XRP Ledger.
Xrplorer was built by Thomas Silkjaer, a Danish data scientist, designer, and popular Forbes Contributor, as a side-project on Neo4j, to prove out the benefits of using a graph database over a traditional relational database management system (RDBMS), which is typically used to store XRP Ledger historical data.
As previously announced, the DeletableAccounts amendment became enabled on the XRP Ledger on 2020-05-08.
The XRP Ledger is currently expected to enable the deletion of on-ledger accounts for the first time, through the DeletableAccounts Amendment, on 2020-05-08 (UTC). This amendment comes with changes to some fairly fundamental details of the XRP Ledger protocol. If you use the XRP Ledger for your business, this is a good time to do a last check to make sure you're ready.

This week on Developer Reflections, we’re proud to highlight XRPScan, one of the most popular blockchain explorers for XRP, used by over 50+ exchanges globally, including Coinbase, Bitfinex, Bitkub, and Bitpay, among others, to look up XRP Ledger account information and show Proof-of-Transaction to their users.
As previously announced, the fixCheckThreading and fixPayChanRecipientOwnerDir amendments became enabled on 2020-05-01.
The DeletableAccounts amendment is still expected for 2020-05-08.

Validators are the lifeblood of the XRP Ledger. This post seeks to explain the function and importance of validators on the XRP Ledger network.
On 2019-01-11, the fixCheckThreading and fixPayChanRecipientOwnerDir amendments lost the support of several validators, causing those amendments' support to fall below the 80% threshold for approval. (EnableAmendment LostMajority transactions: fixCheckThreading, fixPayChanRecipientOwnerDir.) As a result, these amendments are no longer expected to become enabled on 2020-01-18, and their status depends on more validators to resume voting in favor of the amendments.
Version 1.4.0 of the XRP Ledger core server (rippled) contains a change that can cause upgrades to take much longer than usual.
On 2020-01-03, the fixCheckThreading and fixPayChanRecipientOwnerDir amendments to the XRP Ledger gained support from a majority of trusted validators. These amendments were introduced in rippled v1.4.0. Currently, they are expected to become enabled on 2020-01-18. Each amendment that continues to have the support of at least 80% of trusted validators continuously will become enabled on the scheduled date.
