Update Subscription Model Details

Motivation

Up to now, we at Crystal Impact tried to release a new so-called "major update" of our software packages about every 3-6 years. In between, we provide free-of-charge so-called "minor updates" that introduce some minor new features as well as bug fixes.

However, implementing a large amount of new functionality for a new major version that is worth for the customers to pay for is not easy if the still current version has to be further developed in parallel. Maintaining the source codes both of a current "official" version as well as of its still unpublished successors causes a lot of surplus work and is a permanent potential source of new bugs.

In practice, we had to stop development of functionality for a certain version some months after its release and reduce its support to bug fixes, in order to be able to develop and sell the update to a new major version with significantly improved functionality within a reasonable amount of time.

Hence, we have decided to switch over to a so-called "subscription model" that allows us to ensure a more continuous development of our software, and to add new functionality (and bug fixes) as they come along, without having to think about keeping a highlighting new feature back for a potential future major update. For the users this means that new and improved functionality will become available much earlier than with the previous 'major update' model. At the same time, this concept much better suits our daily work and the way we like to develop our software.

The subscription model in practice

With the new model, you can still use your software/license as long as you like (if you have purchased a permanent license), just like it has been with the previous "major/minor update model".

However, in contrast to this earlier model, you will only be able to download updates for a limited amount of time (which is called your "subscription period"; typically 3-5 years): All updates and new versions that are released within your subscription period will be available for download and installation free-of-charge, even if major improvements have been implemented.
Updates of versions that are released after your subscription period has expired cannot be installed and run. If you would like to use these more recent versions, you have to purchase an extension for your subscription.

Schedule

The new subscription model will first be introduced along with the upcoming Match! version 3 in summer 2015. For the current, Diamond and Endeavour will still continue to use the old "major/minor update model". They will be switched over to the subscription model when their next major updates (Diamond 5 and Endeavour 2) become available.
Pearson's Crystal Data is not affected by the new subscription policy, because it is not our own product and the licensing and update conditions are defined by the publisher ASM International.

Purchasing

With the new model, a 3-year subscription is included automatically when you purchase a new license. Additional subscription time can be purchased directly along with the new license or separately sometime later on.

Subscription purchasing can be handled very flexible and totally according to your requirements:

For example, you can purchase a subscription for a long period of time (e.g 10 years) if you currently have funds available from some project, or you can purchase a new subscription frequently (e.g. every 3 years) if you prefer more flexibility.

If you receive some unexpected budget during your subscription period, you can purchase an extension of your subscription period immediately (i.e. you do not have to wait until your subscription has expired). On the other hand, it is also no problem to stop purchasing subscriptions for some time (remember that you can use the software versions that have been released within your subscription period as long as you like), and maybe purchase a new subscription later on when you feel that recent improvements of the software are of interest for you again.

Frequently Asked Questions (FAQ)

Below, you will find some frequent questions that arise in the context of the new subscription licensing model, along with their answers:

Why do you introduce this new subscription based update model?

Up to now, we at Crystal Impact tried to release a new so-called "major update" of our software packages about every 3-6 years. In between, we provided free-of-charge so-called "minor updates" that introduced some minor improvements as well as bug fixes.
However, implementing a large amount of new functionality for a new major version that is worth for the customers to pay for was not easy if the still current version has to be further developed in parallel.

Hence, we have decided to switch over to a so-called "update subscription model". With this new model we are now able to continuously develop our software and add new functionality (and bug fixes) as it comes along, without having to think about keeping a highlighting new feature back for a potential future major update. For the users this means that new and improved functionality becomes available much earlier than with the previous 'major update' model. At the same time, this concept much better suits our daily work and the way we like to develop our software.

Will my software/license expire with the new model?

No. Even with the new model you can still use your software/license as long as you like (if you have purchased a permanent license), just like it has been with the previous "major/minor update model".

However, in contrast to this earlier model, you will only be able to install new updates for a limited amount of time (which is called your "subscription period"): All updates and new versions that are released within your subscription period will be available for download and installation free-of-charge, even if major improvements have been implemented.

Updates of versions that are released after your subscription period has expired cannot be installed and run though. If you would like to use these more recent versions, you have to purchase an extension for your subscription.

Do I have to pay for every update with the new model?

No. All updates and new versions that are released within your subscription period will be available for download and installation free-of-charge.

Updates that are released after your subscription period has expired cannot be installed. If you would like to use these more recent versions, you have to purchase an extension for your subscription, however, this is not mandatory: It is also no problem to stop purchasing subscriptions for some time (remember that you can use the software versions that have been released within your subscription period as long as you like), and maybe purchase a new subscription later on when you feel that recent improvements of the software are of interest for you again.

For which time intervals will subscriptions become available?

Subscription purchasing can be handled very flexible and totally according to your requirements: For example, you can purchase a subscription for a long period of time (e.g 10 years) if you currently have funds available from some project, or you can purchase a new subscription frequently (e.g. every 3 years (which is the minimum period)) if you prefer more flexibility.

It is also no problem to stop purchasing subscriptions for some time (remember that you can use the software versions that have been released within your subscription period as long as you like), and maybe purchase a new subscription later on when you feel that recent improvements of the software are of interest for you again.

When will the new subscription model be introduced?

The subscription model will first be introduced for Match! along with the release of Match! version 3 in summer 2015. For the current, Diamond and Endeavour will still continue to use the old "major/minor update model". They will be switched over to the subscription model when their next major updates (Diamond 5 and Endeavour 2) become available.
Pearson's Crystal Data is not affected by the new subscription policy, because it is not our own product and the licensing and update conditions are defined by the publisher ASM International.

Will the support for Match! version 2 be dropped once version 3 has been released along with the update subscription model?

No, Match! version 2 will still be supported by providing bug fix releases if required as usual. However, new functionality and improvements will only be implemented in the new Match! version 3.

How does the subscription model work technically?

The expiration date of your subscription period will be stored in your license file. While checking your license, Match! also compares its release date that is stored inside the program executable with the expiration date of your subscription period. If the release date is more recent than the expiration date, Match! refuses operation and displays a corresponding information message instead.
The validity of your subscription is already checked during the installation of a new version of Match!. If the subscription period has expired before the new version has been released, the installation will be cancelled and a corresponding information is displayed.
