LimeSurvey 2.50 and recent development

LimeSurvey 2.50 released!

In the past users have asked us repeatedly to revamp the administration interface and surveys.
With LimeSurvey 2.50 we made this come true. On top of that we also revamped the survey templates to be completely responsive for any kind of display - be it a smartphone, tablet or a desktop PC.
We had 2.50 in Release Candidate status for more than 4 months and in general we received very few bug reports from the community.
At some point it became clear that waiting even longer would not yield any more considerable amount of reports, - so we decided to release
LimeSurvey to new users exclusively a couple weeks ago. (For a very short time it was also available to 2.06 users on ComfortUpdate but that was not intended - we apologize for this!).

Finally with this 2.50 release we are receiving a good and wanted amount of bug reports and are releasing a new 2.50+ build version almost daily, with latest translations and latest fixes.
These daily releases are there to show that we take your reports very seriously and we want you to get issues fixed as soon as possible.
We are also very thankful for everyone that contributes to the translations as many texts have changed inside LimeSurvey.

To be fully responsive (we are relying on the Bootstrap framework) the new version 2.50 does not have backward-compatible templates, anymore. Also to deal with contemporary characters like emojis the requirements for the MySQL version were raised to 5.5.2 (this should not be a problem with any decent hoster)

We are asking existing 2.0x users to hold their horses for a very short while longer regarding updating to the latest version as we are still clearing update paths.
You will know when it is cleared, because at that point we will start offering the version 2.50 on ComfortUpdate (as we did with previous versions) and on LimeService.

LimeSurvey 2.06 LTS being available soon

We are aware that there are many professional users who have a big amount of running surveys and it will take them some time and preparation to move to LimeSurvey 2.50. For these users we will be offering a LTS (Long Term support) version that we will provide for at least 6 months. This version will mainly include security fixes and (if anything like this should come up) high-impact bug fixes.
This version will only be made available as download package or by ComfortUpdate to users who bought a Premium/ComfortUpdate package starting in March.

Further roadmap

After 2.5 development and issue fixing has calmed down we will merge 2.5 and 3.0 to extend on making LimeSurvey even more modular for the future.
LimeSurvey 3.0 is currently scheduled for Q4 2016.

LimeSurvey version 2.5 RC available in ComfortUpdate

We recently published the first release candidate of the new LimeSurvey version: LimeSurvey 2.5 . You can read the article we wrote about it few weeks ago to have a quick overview of the changes.

Many of you already downloaded this release, tested it and gave us feedback such as bug reports or new feature requests; we thank all those users for their very useful contribution to the LimeSurvey development. 

To make easier for people to test LimeSurvey 2.5 Release Candidates, we made it available via ComfortUpdate. If your LimeSurvey installation is up to date (and it should because of the security issue found last month), you will now have an update notice about it, and you'll can use ComfortUpdate to test it. If you're not interested, just remove the notice by clicking on its close button.

As said in the notification, you don't need a ComfortUpdate key to update. If you already have a ComfortUpdate key its update count will not be decreased by this update. This is because LimeSurvey 2.5 is still unstable. By the way LimeSurvey 2.5 is using most of the code of 2.06, so it is yet very reliable, and you should be able to use it for your every day work! Most people who did the move told us that the new interface is very intuitive and easy to use.

In the coming weeks, we'll published a new 2.5 Release Candidate, probably the last one. It will use icons font instead of pictures, and will provide an easy way to customize the admin interface with a theme engine based on Sass. It will also provide a new template engine for the survey, based on Bootstrap, using the no-more-tables technique for array question types. So the survey templates will be responsive and will work fine on most smartphones. The more users will update to the release candidate and provide us feedbacks about it, the faster we'll publish the LimeSurvey 2.5 as a stable release.  

So you should test LimeSurvey 2.5, to report bugs, to request new features, to complain about it, to ask for changes, to troll us, to thanks us or to say how wonderful it is ;-) 
You are the LimeSurvey users, we're doing those changes for you, so just don't hesitate.

LimeSurvey Version 2.5 RC released!

The LimeSurvey team is proud to present you the LimeSurvey 2.5 Release Candidate!
Click here to download it!

1. Presentation

LimeSurvey 2.5 is based on the good old LimeSurvey 2 code, but using the famous front-end framework Bootstrap to render its admin interface. So now, you'll enjoy a modern and responsive admin interface to build your survey. If you're a loyal LimeSurvey user, you will not get lost, and you'll still find all the functionalities you care and love.
The development of the new admin interface pursued four goals:
  • Offer a modern graphical experience
  • Respect the habits of loyal LimeSurvey users and the global ergonomy of LimeSurvey 2
  • Easy to use for new users, thanks to an alert info system providing tips and tricks.
  • Keep as much as possible of the LimeSurvey 2 core code to get LimeSurvey 2.5 working as soon as possible 
Soon, we'll also develop a bootstrap responsive template for surveys.
So, LimeSurvey 2.5 is fully compatible with LimeSurvey 2, and you'll can update to it simply using the brand new ComfortUpdate we just released a few weeks ago...

Important changes for the LimeSurvey project

Dear LimeSurvey user,

We would like to inform you about important changes behind the LimeSurvey project.

In this article:
  • Behind the scenes
  • New service: ComfortUpdate
  • Upcoming features & changes for 2.x branch
  • The long run: LimeSurvey 3
  • LimeSurvey user story - Dr. Grieger & Cie. Market Research Behind the scenes

The LimeSurvey project has for a long time been a project driven only by great volunteers - they put in alot of work, all spent from their free time. In later years LimeService (the hosting service) and the LimeSurvey Partners network were created.
However, more and more maintenance is required, not only for the project itself but also for the source code due to its sheer size.
LimeSurvey is now so big and successful that coding new functions/features and redesigning existing features takes usually too much time for a single volunteer coder, who usually can not spare more than a few hours per week.
So we founded the company 'LimeSurvey GmbH' and we are happy to announce that we now hired two full-time coders, Louis Gac and Olle Härstedt, who will work together with our volunteers to speed up LimeSurvey development and create new great features!

New service: ComfortUpdate - 50% OFF

ComfortUpdate is a module in LimeSurvey which helps you to update LimeSurvey to the latest version with a few mouse clicks instead of downloading the files and uploading them to your server.
We rewrote the code behind ComfortUpdate to make it much safer to use & update and ComfortUpdate is now part of a premium package that you can buy at We offer one month of trial use so you can test it out thoroughly and see if it is useful for your future updates.
Also when buying the ComfortUpdate package we currently offer a 50% discount - just use the coupon code 'DISCOUNT50' at the checkout.

Upcoming features & changes for the LimeSurvey 2.x branch

Our immediate goals are now to change two things. At the moment we are coding to give the existing LimeSurvey 2.06 administration a more contemporary design.
If you want to sneak a peak please visit - your feedback is welcome - please note that we are updating the preview version as we go.

On top of that we are working on a responsive template so any survey can easily be used on mobile and desktop devices at the same time. The new template system will be primarily based on the bootstrap framework and this new responsive template also will be the new default template.
To make it fully compatible and completely responsive some changes to the template system will be required which our coders are currently working on.

The long run: LimeSurvey 3

One of our long time team members and volunteers, Sam Mousa, is currently the main developer on LimeSurvey 3  and we are proud that a big part of this development is backed by the World Health Organization. Sam Mousa invested a huge amount of time on this rewrite and our full-time developers will step in soon.
This version is largely a complete rewrite of the 2.0 codebase, with the Central Participant Database completely rewritten, lots of new feature and better performance. We expect to release a stable Version 3.0 by early 2016.

A LimeSurvey user story - Dr. Grieger & Cie. Market Research

The market research firm Dr. Grieger & Cie. Market Research from Germany is using LimeSurvey since 2010. They run online access panels in more than 50 countries on their website They conduct surveys with more than 100.000 participants each month using LimeSurvey. “For us LimeSurvey has always been the preferred choice among so many survey systems out there”, says Gunnar Grieger, founder and owner of Dr. Grieger & Cie. Market Research. “We tested many commercial tools in the past. However, LimeSurvey always met our needs. What we like most is the dedicated support and the continuous development of new features. Good luck, going professional, LimeSurvey!”
