+Pazpar2 may now be operated in a no-merged mode for records.. All records
+will be considered unique. This mode is enabled if no mergekey is
+generated by the normalization stylesheet (pz:xslt).
+
+Pazpar2 caches original records from each target and the 'record' command
+with offset returns the original record if 'syntax' and 'esn' are NOT
+specified. This speeds up retrieval of original records but also means
+that Pazpar2 uses more memory. The cached records will be freed when the
+session terminates or a new search is executed.
+
Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
library part of YAZ is used.
