It costed me several days to upgrade my blog publishing system to WP 2.3. Now, it has been all right, but particulars in some posts have small problems which is caused by transfering characterset from latin1 to utf8. If I have time, I will modify it one by one, since I have less than one hundred posts in non-English language.
Several new features of WordPress 2.3:
- save post in writing automatically;
- database table: tansfering TABLE categories, post2cat, link2cat to TABLE terms, term_relationships, term_taxonomy;
- supporting TAG.
