39 addition to Unix.</li>

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

drh6f63c252001-04-05 16:25:53 +0000[diff] [blame]148<li>The library now assumes data is stored as UTF-8 if the --enable-utf8

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

153 is one of the newer ones that uses UTF-8 internally,
154 then a conversion from UTF-8 to iso8859 and
drh297ecf12001-04-05 15:57:13 +0000[diff] [blame]155 back again is done inside the TCL interface.</li>

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

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

187 load and processor speed and

189 not necessarily mean the library is malfunctioning. No changes to
190 code.
