Loadbalancer.org product roadmap – new features, release notes and more (as always, a work in progress) updated 11th October 2021

Updated on 13 mins

Understandably, we get quite a few requests for a product roadmap containing release notes and feature updates. We've had a chat about this internally and thought that it would be nice to have a permanent post on the blog that we change on the fly as and when customer requirements change. Putting this on the blog enables our customers to express their arguments for and against new features etc. This entry should also give you a better idea of our priorities and how we develop the product.

You can jump straight to our latest update (v8.5.8) here ->

We've changed our focus from v9 later to v8 now...
And we've doubled the size of our development team, which means that we can bring new features to you quickly. We are also changing the way that we release product updates. We have moved to a regular quarterly release cycle, to enable a more rigorous approach to quality.

Releases will be made available at the end of January, April, July and October on a rolling basis. In the event that we need to provide a release to mitigate against a serious security vulnerability, you will be informed and the release will be made off-cycle.

So what can you expect in the next quarterly release v8.6? (Coming soon)

We’ve already added 3 powerful new features:

  • ACL Traffic Rules
    • Easy to use multi-conditional content rules
    • Easy re-ordering and validation in TCP or HTTP mode
    • Modify headers, redirect, block or specify backend servers
    • Support for complex configuration with Free Type rules
  • External Health Checks
    • New Interface making simple to upload, edit and manage
    • Compatible with Layer 4, Layer 7 and GSLB
  • Web Application Firewall
    • Fully integrated CRS3 rule set reducing false positives by 98%
    • New tools for simplifying deployment and maintenance

And we’ve got time to add more..
So shout now if you want something changed — you can contact our CTO directly by emailing miles@loadbalancer.org

How do we decide what to do next on our priority list?

Our principles always guide us, this is an overview of the things we feel are most important in a load balancer appliance in order of priority:

  1. Security
  2. High-availability
    • Constant improvements to underlying systems
    • Future enhancements to intelligence, logging and alerting.
  3. Maintenance
    • Constant focus on close to zero downtime for maintenance and security updates
    • Helping the customer carry out software updates on servers in the cluster.
  4. Performance
  5. Support
  6. Usability
    • Improvements to look and feel + intelligence and ease of use
  7. New platforms
    • Integrate new platforms as and when they become customer priorities i.e. azure
  8. New features
    • Assess against our priorities and implement if, and only if they match our stated priorities.
  9. New products
    • Constantly looking for new applications to help customers with their infrastructure requirements.

Hang on, what happened to v9?
The fabled v9 has evolved into our Partner Product, a customizable, and modular solution that simplifies large scale deployment. It’s already seamlessly embedded into hundreds of critical systems across the globe.

In fact it's grown into a bit of a monster. So while we prepare version 9 for general availability, we have decided to accelerate development of v8 to bring you new and exciting features.


So, what exactly is our partner product?

Put simply, our partner product is a platform for application delivery.
But more importantly it's something we create together — with amazing results. After all not every partner needs all of our services:

  • API driven, vendor agnostic, data plane agnostic centralized application delivery
  • Fully automated deployment, maintenance & monitoring of your applications
  • Tight integration with your development team and your roadmap
  • Our support integrated with your customer service team
  • OEM Hardware development, deployment, certification and logistics
  • Centralized management of security and version control
  • Flexible contracts with long term commitments to your roadmap

Why do you need our partner product?
You are a respected technology vendor in your sector. And you have a large number of customers depending on your systems. And it's getting increasingly complex to support them on a global scale — while keeping the pace of innovation going with your own product roadmap.

I'm sure your system has unique requirements:

But wouldn't it be great to work with someone who wants to help you increase your revenue & customer satisfaction, while reducing complexity & costs?

Don't worry: We'll still be updating & supporting v8 for a very long time!

  • SSL PROXY BIND: Fix broken proxy bind if you modify the layer 7 VIP or delete the termination SSL VIP.


10th September 2018

  • HyperV: We have improved the HyperV live migration and as a result this no longer causes potential heartbeat latency issues.

  • WAF: The WAF interface has now been simplified, and we've added easy log diagnosis & automated whitelist suggestions. We've also added a new fast page cache, for accelerating Wordpress.

  • SSL: The interface has been simplified and OpenSSL has been updated to 1.1.0h.
    -- STunnel has been updated to 5.46 to resolve a slow memory leak when reloading 1000's of SNI rules.
    -- Automated certificate generation is now available, using Let's Encrypt.
    -- We have increased the number of SNI rules you can add via the web interface to 8000!

  • HAProxy: Has now been updated to 1.8.11. The core change being the ability to configure multi-threading for greater than 10G performance.

  • Other: Bonded interface limit has increased - you can now create up to 4 bonded pairs with full 802.3ad support.


  • Azure: AZ HA service can now run scripts on failure.
    -- SNAT Mode with HA now displays the correct VIP in the system overview on the slave appliance.
    -- SNAT Mode with HA wrong slave appliance IP selected on 'modify VIP page'.

  • PBR: You can now start/stop a single set of rules without having to re-write/affect all PBR services.

  • GSLB: GSLB is now available and configurable from the interface. Yup! I didn't believe it either. We have finally caved to your constant demands for GSLB! Actually Aaron finally found some really powerful uses for it on customer sites as explained in his blog about full GSLB support in v8.3.1.

  • HAProxy: Haproxy updated to 1.7.10 and re-encrypt to backend is now available in TCP mode.

  • Layer 4: LVS SNAT mode has been added giving you the performance of layer 4 load balancing for TCP and UDP without the requirement of making server or infrastructure changes. Why we didn't do this earlier - I don't know, because it's great!


  • The only change between v8.2.5 and v8.3 was a BIG update of the Linux Kernel from our existing 2.6.35 all the way to 4.4.49.
  • We have done a lot of testing with the new Kernel and we are very happy with the performance improvements.


  • Enhanced performance and new double login feature for our WAF
  • Improved SSL hot reload to guarantee zero downtime
  • PROXY protocol no longer requires a separate VIP on port 81
  • API fully updated with 98% of functions available
  • Big performance updates for the WAF went into v8.2.5, we also added the new double login and Google Authentication features.


In the process of designing our WAF implementation we've been having a lot of conversations with Sucuri, these guys are awesome and know everything about web application firewalls and denial of service protection. Sucuri are also way more friendly than Incapsula (who were impossible to get any straight answers from).


  • More wizards for setting up specific applications
  • Dynamic graphing and dynamic numerical stats
  • Re-write and enhancement of the initial configuration wizard(s)
  • Layer 7 email alerts - as usual we've released it open source before actually putting it in our product (how do we make any money anyway?)


  • Re-write of the security model for pairing master and slave units - for full security compatibility with cloud platforms AWS and Azure.


  • Overhaul of system overview
  • Loads of improvements to the web interface in general, making it easy to use as well as nice to look at


  • Layer 7 external health checks i.e. NTLM proxy health checks
  • Enhancements to layer 4 maintainability and matching behaviour to be similar to layer 7 (especially the fallback server)
  • Hardware compatibility/performance updates for new hardware models i.e. Dell R220
  • Moving the full v7.x application to the Amazon EC2 cloud platform.
  • Kernel improvements for multiple hyper-visor platforms VMWare, XEN, Hyper-V, KVM & EC2
  • Improvements to the layer 7 HAproxy stateful restart and replication model
  • Automated contrack tuning and irq balance performance updates
  • Re-write of the user security model in the web interface
  • Performance and functionality improvements to the windows feedback agent
  • Port of the full product to Microsoft Azure cloud platform - in progress but trying to make the Kernel secure without access to the Microsoft source code is fun!

Other previous updates....

  • SNI support in the web interface
  • WAF / Mod_Security: We've ensured that our Layer 7 rate limiting enables seamless protection for each WAF instance by default, because the last thing we want is the WAF itself being an easy way to DOS our load balancer!
  • Simple ACL redirects and rules with support for manual backend configurations
    API & LBCLI improvements
  • AWS - automatic one click integration with auto scaling groups
  • Complete re-write of the disaster recovery functionality - NO DOWNTIME!
  • Several performance enhancements for specific types of traffic.

And then we have some features on the soon to be scheduled / wish list:

  • Full re-write of the high-availability subsystem (heartbeat) focusing on stability and scalability and intelligence for multiple nodes.
  • Plug-in architecture and wizard for controlling the auto-scaling of backend servers in clusters - that would be fun/interesting.
  • Enhancements and intelligence into real server health monitoring
  • Easy to use Denial of Service rules- manual config.
  • Simple rules to direct users to different clusters when the primary one is busy i.e. busy e-commerce site flood control - manual config.
  • Easy and secure remote access to customer load balancers from Loadbalancer.org support staff
  • Easier integration of existing authentication methods i.e. RADIUS/LDAP/Active Directory

Things we are not doing:

  • SNORT - Why? But we might make DDOS protection more automated..
  • iPhone/iPad/Android apps
  • Graphical firewall
  • Firewall load balancing - we could ask Horms very nicely to modify the Linux Kernel for this...maybe...
  • Bridge based load balancing - yuck...But a LOT of people use web filters and WAFs in bridge mode so something like the Net Optics xbalancer solution makes sense.
  • Link balancing - really? I don't think so. And here's why...
  • TMG SSO replacements - Yuk. Although, Andrew might look into doing this during his downtime (our developers get 14 hours a week free/fun/downtime).
  • Making anything more complicated, or harder to use....

Obviously this blog post needs a lot of work...and will change rapidly...please comment below, thanks.
