New Solr versions are released quite frequently. Since we wrote about 4.7 back in March, we got Solr 4.8 on April 28th, 4.8.1 May 20th, 4.9.0 June 25th, 4.10.0 September 3rd, 4.10.1 September 29th, and 4.10.2 on October 31st.
Here are my favorite highlights:
- Managed stopwords and synonyms. You can now modify these dicationaries through a REST API (4.8)
- Nested child document support for JSON updates (4.8)
- TTL for documents, i.e. Solr will delete documents for you after expiry (4.8)
- Start script in bin/solr for easier startup and auto setting JVM options (4.10)
- Interval Faceting for easier range specification on unequal ranges, such as prices (4.10)
- Tons of bug fixes!
Haven’t upgraded Solr for some time? Note that Solr requires Java 7 since version 4.8!
Important: Version 4.10.x will be the last release on 4.x. Soon coming version 5.0
