PCI-SIG has released version 3.0 of the Conventional PCI specification. Revision 3.0 is the latest version of the Conventional PCI specification that builds upon version 2.3 and completes the migration of the PCI bus from the original 5.0V (volt) signaling to 3.3V-only slots. The new Conventional PCI 3.0 spec completes the migration to 3.3V-only slots by removing support for 5.0V-only keyed add-in cards. Universal keyed add-in cards (cards that are keyed for both 5.0V and 3.3V slots) continue to be supported by the Conventional PCI 3.0 spec. Version 3.0 also incorporates the errata and ECNs (Engineering Change Notifications) to version 2.3 specification. Version 3.0 supports multiple bus specifications: PCI 66, PCI-X, Mini PCI, and Low Profile PCI.
