37 unreadable after a DROP TABLE due to corruption to the SQLITE_MASTER
38 table.</li>
39<li>Change the code so that version 2.1.1 databases that were rendered
40 unreadable by the above bug can be read by this version of
41 the library even though the SQLITE_MASTER table is (slightly)
42 corrupted.</li>

76 addition to Unix.</li>

drh382c0242001-10-06 16:33:02 +0000113<li>Removed some unused "#include <unistd.h>" that were causing problems
114 for VC++.</li>

125 using compilers other than gcc.</li>

127 newlines anywhere in the data. This is an old bug that was carried
128 forward from version 1.0. To fix it, the ".dump" output no longer
129 uses the COPY command. It instead generates INSERT statements.</li>
130<li>Extend the expression syntax to support "expr NOT NULL" (with a
131 space between the "NOT" and the "NULL") in addition to "expr NOTNULL"
132 (with no space).</li>

drhb19a2bc2001-09-16 00:13:26 +0000152<li>Initial release of version 2.0. The idea of renaming the library
153 to "SQLus" was abandoned in favor of keeping the "SQLite" name and
154 bumping the major version number.</li>
155<li>The pager and btree subsystems added back. They are now the only
156 available backend.</li>

drh6f63c252001-04-05 16:25:53 +0000185<li>The library now assumes data is stored as UTF-8 if the --enable-utf8
186 option is given to configure. The default behavior is to assume
187 iso8859-x, as it has always done. This only makes a difference for
188 LIKE and GLOB operators and the LENGTH and SUBSTR functions.</li>
189<li>If the library is not configured for UTF-8 and the Tcl library
190 is one of the newer ones that uses UTF-8 internally,
191 then a conversion from UTF-8 to iso8859 and
drh297ecf12001-04-05 15:57:13 +0000192 back again is done inside the TCL interface.</li>

196<li>Added limited support for transactions. At this point, transactions
197 will do table locking on the GDBM backend. There is no support (yet)
198 for rollback or atomic commit.</li>
199<li>Added special column names ROWID, OID, and _ROWID_ that refer to the
200 unique random integer key associated with every row of every table.</li>
201<li>Additional tests added to the regression suite to cover the new ROWID
202 feature and the TCL interface bugs mentioned below.</li>
drh960e8c62001-04-03 16:53:21 +0000203<li>Changes to the "lemon" parser generator to help it work better when

209<li>When doing DELETE and UPDATE, the library used to write the record
210 numbers of records to be deleted or updated into a temporary file.
211 This is changed so that the record numbers are held in memory.</li>
212<li>The DELETE command without a WHILE clause just removes the database
213 files from the disk, rather than going through and deleting record
214 by record.</li>

224 load and processor speed and
225 to warn the user that a failure of one of those (rare) tests does
226 not necessarily mean the library is malfunctioning. No changes to
227 code.

drhb0729502001-03-14 12:35:57 +0000234 NULL. The problem does not appear Windows, Linux, or HPUX but does
