Most Stable Version of Drools - scala

We are planning to use Drools in our organisation with Scala/Spark. We have selected Drools Version 5.3.0 and 7.15.0 for our use but we have some stability doubts between them because Version 7.15.0 has recently launched & we are not sure whether it is stable or not.
We have practiced with Version 5.3.0 but we want to know the life cycle of it. What if after some time, Version 5.3.0 will not available for use or some update is brought for this?
So please help us to chose between them which version should we chose for longer use.

Drools 5.3 is outdated version and its not under development. Its better you go with latest release.Drools 7.15 is also stable, but if you are planning to use it for business critical application then I will recommend you to go with enterprise release of Drools 7.x , i.e Red Hat Decision Manager. With enterprise release will get patches for known issue on regular basis and one-off patch for critical issues.

Is there a "stable" version to use of the npm packages ui5/cli & sap-ux-tooling?

To my knowledge, the latest non-alpha version of the #ui5/cli and #sap/ux-ui5-tooling (as of 2nd March 2022 - version 2.14.6 and 1.5.0 respectively) are the ones to use.
However, I wanted to confirm as my organisation has multiple ui5 projects and so having a standardised version of the #ui5/cli and #sap/ux-ui5-tooling dependencies could prevent issues around bugs in tooling.
If the advice is just to use the latest non-alpha version, then I just need to update the dependencies regularly.
The versions you mentioned should be your choice to use in a productive environment.
The upcoming UI5 tooling 3.0 is not.
I don't think you will achieve the same version in every app because of the lifecycle.
The packages are fast paced and when u have a stable app deployed you will not update it every month I think.
I would not invest time to find the perfect tooling version.

Installing older version of AnyLogic or downgrading AnyLogic

The newest AnyLogic version is not supported by my current AnyLogic license. The license only supports up to 8.3.3. However, I do wish to install AnyLogic on another computer and activate it with my license. However, surprisingly I could not find downloads of earlier AnyLogic versions. Does anyone know if and where I can find these earlier versions, and whether I perhaps can downgrade a newer AnyLogic version?

For any version, just put the version you want and you will likely be able to download it
if using mac:
https://www.anylogic.com/files/anylogic-professional-8.3.3.dmg
In addition to Felipe's answer, you can always ask
support#anylogic.com
if you need very old versions. I believe that AL7.x is not available online anymore but they happily send the installers if you need them.

Difference between wildfly 9.0.1 vs 8.2.1

I am seeing 2 versions (9.0.1 vs 8.2.1) of wildfly which were released on the same day. What is the difference between two versions and why there are 2 versions exist in parallel? I couldn't find it over the internet.
Wildfly ships on a very fast development cycle. Each major release 8.x, 9.x, 10.x contains major changes from the previous version. All current major work is being done on the 10.x beta versions.
The minor versions are for bugfixes related to that particular release. Since there are now people in production with both 8.x and 9.x, any critical bugs or security patches go into one of these releases. It is very possible a security issue could exist and be fixed in both 8.x.1 and 9.x.1.
JBoss EAP, which is based on WildFly, deliberately has a slower release schedule. For each major version they release they offer paid support for 4 years, so they change major versions much slower.
There is a good slide of the lifecycle of WildFly/JBoss on page 9 of this slide-deck from the RedHat Summit in June:

Here is the official announcement for the pair of releases: -

Which version of JBoss AS to use?

We are using JBoss 4.2 GA, and need use a newest version in some new project.
I heard that JBoss 5.0 encounter such bugs... is this correct?
If not, which exact version of 5.0 to use?? and what about 6.0??
Thanks.
JBoss AS 5.1 is perfectly fine. Every app server has bugs, they're big, complex applications in themselves, but 5.1 is solid.
JBoss AS 6 hasn't been released yet, it's still in beta.
Jboss Application Server 7 is released, and up to a beta version of 7.1.0. You can download a copy here, and find the Getting Started Guides here.
As with any major revision of an application server, there are significant changes that might impact upon your business and will need to be considered in the context of your use case. Being an open source project, the early praise and early bugs are in the public arena, so it is easy to research for yourself.
Working on a documentation project involving AS7 I have seen some of the great work that the team has undertaken, and I couldn't imagine going back to a previous version now I've enjoyed the fast boot-up times, the ease of application deployment, custom configuration and the powerful Management CLI.
These kinds of improvements and features, not just constrained to JBoss Application Server or JBoss Enterprize Application Platform, speak volumes about the speed, stability and usability that will be increasing exponentially in this field for all competitors over the coming years. I'd urge you to check out the current generation of application servers if your experience is largely with JBoss AS 4.2.

Vignette V8 Upgrade

Vignette upgrades are usually not straightforward. You basically have to do a new installation and migrate over all of your customizations etc. Does anyone know if the upcoming V8 version is easier to upgrade or if its easier to upgrade from a certain previous version compared to earlier version. So I can upgrade to an earlier version (say 7.6) and then hopefully its easier?
Vignette v8 is officially not out yet, its only been soft released to some selected clients. My guess is that the upgrade will not be very straightforward but I've no concrete information on that.
During the wait you might also be interested in an open source alternative of Vignette v8 freely available: Sense/Net 6.0 http://blog.sensenet.hu/post/2009/08/05/An-Open-Source-Alternative-for-Vignette-v8.aspx
I have finally found the answer. You do need to upgrade to 7.6 before upgrading to 8.0 from an earlier version.
