Commitment to our NPrinting customers

 

Support for Qlik NPrinting version16 is scheduled to end on March 31, 2019. However, based on customer feedback, Qlik has decided to continue Extended Support for all NPrinting 16 customers, who are current on maintenance, at no additional charge. Extended Support for NPrinting 16 will be available until March 31, 2020.

 

The availability of Extended Support for NPrinting 16 is to provide our valued customers with ample time to migrate to a fully featured and supported Qlik NPrinting product and is not an indication that customers should stay on NPrinting 16 indefinitely. Over the next year, Qlik will focus on adding remaining gap features from NPrinting 16 to NPrinting 18+ such as On-Demand for Qlik Sense®, advanced search filters, task notifications, variable filters, select excluded filters as well as variables in the email subject line and body. Additionally, Qlik is working to provide a migration tool to help customers migrate their reports, connections, filters and tasks from NPrinting 16.

Hi all Qlik Customers,

 

Summer, at least in northern parts, is here and along with that Qlik has a bumper crop of releases for you.  Qlik Sense June 2018 is now available with a host of new features.   You can find information about new features and functionality in Sense June 2018 Qlik Sense Product Innovation Blog.    Qlik Sense June 2018 includes the first iteration of Qlik Sense Multi-Cloud which is a new feature and is license controlled.   Access to Qlik's Multi-Cloud release is being controlled so we can ensure the best possible customer experience and keep you updated on key developments, best practices and resources to assist with your project success.   Please contact your local Qlik Account Manager or Qlik Partner for specific details on how to gain access to the release.

 

With the June 2018 Qlik Sense Enterprise release, Qlik will introduce updates which streamline the Qlik Sense client packaging through the introduction of Webpack, a new technology for module bundling JavaScript® applications. The introduction of Webpack technology will impact a subset of extensions and mashups that make use of unsupported internal Qlik Sense libraries or “private libraries” as described below.  Any solution, i.e. mashups or extensions that make use of a “private” Qlik Sense library should continue to function, but as with all upgrades, testing of your solutions is strongly recommended.  To address the need for use of these unsupported private libraries, Qlik will explore additional public APIs in forthcoming releases.   See the attached FAQ for further information.

 

Qlik NPrinting June 2018 is also released along with GeoAnalytics June 2018.   You can find information on NPrinting features and fixes in the attached release notes.

 

All of our releases are now available on our download site.   As always if you have any questions please contact Qlik Support through chat, telephone or through the Support Portal.

 

Kind regards

Hi Qlik Web Connector users,

 

If you are a Klout user you should be aware that this platform is being shut down as of today, 25th of May 2018 - see Klout Shuts Down.   Therefore our Klout Web Connector will no longer work and it will be removed from our connector bundle from June onwards.  If you continue to try to use the Klout Connector you will get an error - this is not a Qlik issue and you can prevent the problem by removing Klout data loads and connections.   If you don't use the Klout Connector you will be unaffected.

 

Thank you for choosing Qlik software, if you have any questions please don't hesitate to contact Support.

 

Kind regards

Commitment to our QlikView Customers

In accordance with Qlik®’s Maintenance Policy, standard support for QlikView 11.20 has ended as of March 31, 2018. However, based on customer feedback Qlik has decided to make Extended Support available to all QlikView 11.20 customers who are currently on maintenance, at no additional charge. Extended Support for QlikView 11.20 will be available until at least March 31, 2019.

The availability of Extended Support for QlikView 11.20 is to provide our valued customers with ample time to upgrade to the fully supported QlikView product, and is not an indication that customers should stay on QlikView 11.20 indefinitely. Further, Extended Support is not an extension of standard support and maintenance under the Qlik Maintenance Policy. It consists only of troubleshooting and fixes that are issued as patches at Qlik’s discretion. Only severe, mission critical issues will be considered for resolution in QlikView 11.20, and there will be no product enhancements to QlikView 11.20 as part of Extended Support.

 

 

The current fully supported versions of QlikView are QlikView 12.00, 12.10, and 12.20. To receive all the benefits of Qlik’s support services (including, but not limited to, product enhancements and service releases) customers must be on one of these versions and current on maintenance fees. The latest versions of QlikView have the benefit of cumulative quality improvements, so we strongly recommend upgrading to the latest version. Qlik Consulting services is well versed in the upgrade process, and can aid both customers and partners to facilitate this transition. We suggest you take advantage of this time to plan your upgrade for the coming year.

 

 

Qlik remains fully committed to QlikView and will continue to invest in it for the foreseeable future. With each new release, we deliver engine-level improvements from Qlik Sense®, increased product quality and performance, and new features such as advanced analytics integration and on-demand app generation. Our QlikView customers can take advantage of ongoing product innovations by continuing the QlikView journey on our latest supported versions.

 

 

For more information on our product roadmap for QlikView, please refer to our statement of direction.

 

 

Thank you.

In case you forgot:

Meltdown and Spectre are the names of two serious security flaws that have been found within computer processors. They could potentially allow hackers to steal sensitive data without users knowing.   We previously posted this information back in January, and here is an update in full.

 

The fixes needed to protect against Meltdown and Spectre might have the unfortunate side effect of having significant performance impact on Windows and Linux operating systems.

 

What is Meltdown?:

 

Meltdown is a security flaw that could allow malicious software to illegally access memory that belongs to the kernel, or another software process. It works by circumventing the memory barriers between applications run in user space and kernel space by an attack involving speculative execution. A branch mis-prediction is provoked in one of several ways, causing the CPU to speculatively execute an illegal code sequence. This is caught by the CPU after the branch is executed, and subsequently rolled back. However, its effect on the hardware cache is not rolled back, and measuring the response time of various accesses to the cache can pinpoint what data was stored in the memory of the victim process through the address space of the adversary.

 

The software fix involves separating the memory page tables of the user space and kernel space, which inevitably leads to a negative performance impact on communication between user level applications and the kernel.

 

What is Spectre?

Spectre is a security flaw that affects modern microprocessors that perform branch prediction. It can be used to trick otherwise error-free applications into giving up secret information by taking advantage of a delay in the time it may take the CPU to check the validity of a memory access call.

 

Mitigation:

 

The following table describes what needs to be done in Microsoft Windows environments to mitigate the Meltdown and Spectre security flaws.

(1) The operating system patches

have to be enabled in the Windows registry or they will not have any effect. See "Enabling protections on the server" here: https://support.microsoft.com/en-za/help/4072698/windows-server-guidance-to-protect-against-the-speculative-execution


How is Qlik software impacted?

Qlik products are built on top of underlying components such as Operating Systems (OS) and chipsets, therefore Qlik products will rely on the OS fixes for both Spectre and Meltdown to mitigate the security risks.

 

The Qlik Performance and Stability centre are in the process of testing both QlikView and Qlik Sense with operating systems and system BIOS patches that address the Meltdown & Spectre security flaws. Tests include measuring the load of concurrent users ranging from low to high load scenarios. High load in this case is a continuously growing number of concurrent users (up to 300) triggering light calculations with minimum think time between the clicks. The users avoided selecting cached values. The complete bandwidth of the system was tested since the processor needed to calculate every result, which meant that a queue of clicks to serve was built up.

 

The following conclusions are based on the results of the ongoing tests with currently available patches. We are sharing our conclusions here in the spirit of openness and transparency and they may change as more results are gathered.

 

Configuration

 

 

Conclusion

 

Qlik Sense on Windows

 

On dual-socket servers, the performance degrade was 4 - 14% (seemingly depending on the CPU generation).

On quad-socket servers, the performance degrade was smaller with the updated Spectre patch than with the original patch:

•The largest degrade was measured with hyper-threading enabled: the response time increased 8 - 60% (used to be 90% with the original patch).

•With hyper-threading disabled, the performance degrade was smaller, 5% - 40%.

•When testing the updated patch on a quad-socket server with fewer cores, the performance degrade was less significant. SEE NOTE (2)

 

QlikView Server

 

Results are similar to those for Qlik Sense.

On dual-socket servers, the performance degrade was 5 - 11%.

Based on the March 2018 test results, it is recommended to install the updated version of the Spectre patch. SEE NOTE (2)

 

NPrinting

 

No degrade for Qlik Sense.

A degrade of around 10% for QlikView Server.

 

(2) NOTE Important note regarding the Spectre patch: (update 2018-04-12)

 

The original Spectre patch, released in January 2018, caused stability issues and it is recommended not to install that patch. However, it is recommended to install the updated version of the Spectre patch, which was released in March 2018.
