+-- 4.2.20 2011/11/09
+
+New ZOOM connection setting: tproxy. It's like proxy, but does not
+set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
+to set resolved address + port for a connection outside ZOOM itself.
+
+Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
+
+-- 4.2.19 2011/11/07
+
+Fix uninitialized variable in Solr spell support (could cause SEGV
+for SRU response decoding).
+
+Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
+back-end's addinfo through into the ZOOM response addinfo.
+
+When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
+they are separated by a colon and a space rather than simply
+concatenated.
+
+-- 4.2.18 2011/10/28
+
+Add support for Solr spell-checking/suggestions through ZOOM.
+If a Solr target has been configured correctly for spelling-checking
+and suggestions, these will now be returned on the ResultSet option
+"suggestions". zoomsh has been extended to show this with the cmd suggestions.
