Mainly a bugfix version and improved SMP scaling.
Unfortunately no big elo gains, probably 20-30.
Build using Java 14 but also a Java 11 binary has been supplied.

I have already java 8 and java 11 installed. Shall I install java 14 too? Is there a difference in strength when using different java versions?

If possible, I would only install the latest version which is 14 and uninstall all older versions.Gabor Szots wrote: ↑Mon Apr 27, 2020 9:02 am

If you don't feel like installing a newer version, just uninstall 8 and use 11.
Strength difference between 11 and 14 is negligible I think.

I have just installed jdk 14, so now I have 3 java versions installed.sandermvdb wrote: ↑Mon Apr 27, 2020 11:34 amIf possible, I would only install the latest version which is 14 and uninstall all older versions.Gabor Szots wrote: ↑Mon Apr 27, 2020 9:02 am

Strength difference between 11 and 14 is negligible I think.
However, I have had two problems with java 11:
1. Some older java engines run only with java 8.
2. Java 8 is regularly updated (automatically), while java 11 is not.
Besides, I don't know how to use them in parallel. If the path environment variable is overwritten (which I prevented so far) then I think all java engines will try to use java 14 unless explicitly told to use java 8 (in which case I have to edit all files invoking java 8, which is a PITA).

Strange that you need Java 8. I thought all Java versions were backwards compatible.Gabor Szots wrote: ↑Mon Apr 27, 2020 12:24 pm I have just installed jdk 14, so now I have 3 java versions installed.

Now I'm thinking about it, it is true that they removed some libraries from newer Java versions and apparently some engines you use require these libraries. You could however download these libraries manually.
I think that the easiest approach for you is to update the paths to the Java 8 engines to your actual ProgramFiles\Java\bin folder. New engines then can use the latest Java version by using the path variable.
I don't see any reason that you need Java 11.

I have just tried two relatively old java engines (Mediocre and Fischerle) with java 14 and they seem to work.sandermvdb wrote: ↑Mon Apr 27, 2020 2:54 pm Strange that you need Java 8. I thought all Java versions were backwards compatible.

I am going to delete both 8 and 11 and use 14 exclusively. I have downloaded OpenJDK14U-jdk_x64_windows_hotspot_14.0.1_7.msi and openjdk-14.0.1_windows-x64_bin.zip. Do you think I should use the msi for installing (then I'll reinstall, deleting the one I created using the zip file)?
