Apache Solr 5.4.1 发布，更新如下：

• Bug Fixes   (8)

1. SOLR-8460: /analysis/field could throw exceptions for custom attributes.
   (David Smiley, Uwe Schindler)

2. SOLR-8373: KerberosPlugin: Using multiple nodes on same machine leads clients to fetch TGT for every request
   (Ishan Chattopadhyaya via noble)

3. SOLR-8059: &debug=results for distributed search when distrib.singlePass (sometimes activated automatically) could result in an NPE.
   (David Smiley, Markus Jelsma)

4. SOLR-8422: When authentication enabled, requests fail if sent to a node that doesn't host the collection
   (noble)

5. SOLR-7462: AIOOBE in RecordingJSONParser
   (Scott Dawson, noble)

6. SOLR-8496: SolrIndexSearcher.getDocSet(List<Query>) incorrectly included deleted documents when all of the queries were uncached (or there was no filter cache).  This caused multi-select faceting (including the JSON Facet API) to include deleted doc counts when the remaining non-excluded filters were all uncached.  This bug was first introduced in 5.3.0
   (Andreas Müller, Vasiliy Bout, Erick Erickson, Shawn Heisey, Hossman, yonik)

7. SOLR-8418: Adapt to changes in LUCENE-6590 for use of boosts with MLTHandler and Simple/CloudMLTQParser
   (Jens Wille, Ramkumar Aiyengar)

8. SOLR-8561: Doing a rolling upgrade to 5.4.0 fails because the new nodes cannot find the shard leader properties where they expect. This bug was first introduced in 5.4.0 and a fallback was added so that the leader properties are searched in both the old location and the new one.
   (Shai Erera)

• New Features   (1)

1. SOLR-8470: Make TTL of PKIAuthenticationPlugin's tokens configurable through a system property (pkiauth.ttl)
   (noble)
