97 newlines anywhere in the data. This is an old bug that was carried
98 forward from version 1.0. To fix it, the ".dump" output no longer
99 uses the COPY command. It instead generates INSERT statements.</li>

102 (with no space).</li>

drh6f63c252001-04-05 16:25:53 +0000[diff] [blame]155<li>The library now assumes data is stored as UTF-8 if the --enable-utf8

157 iso8859-x, as it has always done. This only makes a difference for
158 LIKE and GLOB operators and the LENGTH and SUBSTR functions.</li>

160 is one of the newer ones that uses UTF-8 internally,

167 will do table locking on the GDBM backend. There is no support (yet)
168 for rollback or atomic commit.</li>
169<li>Added special column names ROWID, OID, and _ROWID_ that refer to the
170 unique random integer key associated with every row of every table.</li>
171<li>Additional tests added to the regression suite to cover the new ROWID
172 feature and the TCL interface bugs mentioned below.</li>

180 numbers of records to be deleted or updated into a temporary file.
181 This is changed so that the record numbers are held in memory.</li>
182<li>The DELETE command without a WHILE clause just removes the database
183 files from the disk, rather than going through and deleting record
184 by record.</li>

194 load and processor speed and
195 to warn the user that a failure of one of those (rare) tests does
196 not necessarily mean the library is malfunctioning. No changes to
197 code.
