last week I found WP2.0.3 has been published.
Aftering reading the operation of upgrade
I took 15 minutes to finished upgrade.
The processing of upgrade is fairly simple,just rewrite old files with the latest ones.
WP official webisite claims it is a bug fix and security release, and is recommended for all WordPress users.
• Small performance enhancements
• Movable Type / Typepad importer fix
• Enclosure (podcasting) fix
• The aforementioned security enhancements (nonces)I feel the speed is assuredly faster
