Old codecs may only be used for reading

Hi

I recently upgraded from Lucene 9.8.0 to Lucene 9.9.1 and noticed that Lucene95Codec got moved to

org.apache.lucene.backward_codecs.lucene95.Lucene95Codec

When testing my code I received the following error message:

"Old codecs may only be used for reading"

Do I understand correctly, that Lucene95Codec can not be used for writing anymore?

And that I should use now Lucene99Codec for writing?

Thanks

Michael

Hi Adrian, thank you very much for confirming quickly!

I switched to Lucene99Codec and all looks good again :-)

Thanks
