Oxen 9.2.0
This release is a mid-fork, mandatory upgrade for Service Nodes. (This is brand new as it's the first time we're doing this). The main point of this release is to unify the network on new versions of the Oxen Storage Server and Lokinet routers as both contain a slew of improvements and fixes for the benefit of Lokinet and Session.
Very little has changed in Oxen-core itself: mainly just changes around requiring new lokinet/storage server versions, enforcing that on the network, and adding support for this new type of "mandatory service node upgrade" release.
Note that upgrading to this release is required for Service Nodes, along with lokinet 0.9.5 and oxen-storage-server 2.2.0. Upgrade enforcement (i.e. decommissions and/or deregistrations) will begin at block 839009 (due 13 July, 23:00 UTC).
This release is not required for wallets, exchanges, and other non-service nodes: it does not change the blockchain rules, but rather only changes the requirements for service nodes.
A brief overview of the (overall) upgrades contained here:
Lokinet 0.9.5 - stability and performance improvements
Since the initial hard fork (9.1.0) we've identified several issues in the 0.9.x Lokinet release, and have been steadily working on fixes and improvements in the 0.9.x releases up through the current 0.9.5 release. The most important of these were in the 0.9.4 release, which includes fixes to how lokinet service nodes talk to each other. Though the 0.9.4 release has been out for several days, unfortunately the fixes require an updated version to the entire network; hence this mandatory upgrade.
We've also made improvements to lokinet's memory footprint, especially over time; our testing shows routers using approximately half the memory after running for a week.
Storage Server 2.2.0
The Oxen Storage Server sees a significant overhaul in this release aimed at making it more performant, more reliable, and easier to add to in the future. At a higher level, these changes include new features allow clients (like Session) to directly delete some or all messages, to update expiration dates for messages, and allows clients to reliably use this new functions plus deposit new messages more easily by only having to contact a single swarm node with reliable confirmation of the storage/deletion/retrieval being delivered to all members.
The Storage Server updates also significantly unifies our communication technology stack -- with this update, we are using the same libraries for communication (oxenmq for node-to-node; cpr for making HTTP requests; and uWebSockets for handling HTTP requests) among all the core software (oxen-core, oxen-storage-server, lokinet-router).
Similar to lokinet, this release also brings significant memory reductions for operating service nodes, particularly once storage server has been running for a few days.
Release binaries
As usual, we recommend installing the updates for Debian and Ubuntu based systems from our apt repository, though we also support self-compiled and static builds that we upload here.
