# Eclipse Photon (4.8) Plug-in Migration FAQ

1. Apache Batik bundle changes
2. Apache Lucene bundle changes

## 1. Apache Batik bundle changes

As part of the migration of Eclipse Platform to Batik `1.9.0`, the third-party Apache Batik bundles changed in the following way:

1. Bundle `org.apache.batik.css` was bumped to version `1.9.0`.
2. Bundle `org.apache.batik.util` was bumped to version `1.9.0`.
3. Bundle `org.apache.batik.util.gui` version `1.8.0` was removed. It was a dependency of version 1.8.0 of `org.apache.batik.util.gui` bundle but it is no longer a dependency of version 1.9.0.
4. Bundle `org.apache.batik.i18n` version `1.9.0` was added as it was needed by bundle `org.apache.batik.css`.

## 2. Apache Lucene bundle changes

As part of the migration to Lucene 7.1, the third-party Lucene bundles were updated from version 6.1 to 7.1.

1. Bundle `org.apache.lucene.core` was bumped in version so consumers should not see any difference except the changes of Lucene itself (see link below).
2. Bundle `org.apache.lucene.misc` was removed as it is no longer used by Eclipse Help system.

See Lucene Change Log for details on how the Apache Lucene changed between these versions.
