The latest version of µITRON3.0 is Ver 3.02.00. Changes made since the µITRON3.0 Standard Handbook was released (Ver 3.00.00) are noted in Newsletter No.5 and No.11, as well as in ITRON Standard Guidebook~2.
The ITRON Standard Guidebook 2, which is a general introduction to the ITRON specifications, deals primarily with µITRON3.0. Meanwhile, the earlier ITRON Standard Guidebook '92-'93 remains as a valuable reference for use with the µITRON (Ver 2.0) and ITRON2 specifications, even though the dates in its title are now past.

The official checksheets can be obtained from here (in Japanese).
The µITRON3.0 compatibility checksheets are intended mainly for use in comparing different OSs implemented based on the µITRON3.0 specification, and for estimating the amount of work involved in porting applications from one µITRON3.0-based OS to another. The checksheets make it easy to determine the extent to which each OS implements optional features of the µITRON3.0 specification, or in cases where the specification offers a choice, to determine which choice was taken. Moreover, they are designed so the data can be read into a computer. The data is then readily converted to tables or graphs that tell at a glance the functions supported by each OS, or to a form for ready comparison of two or more OSs.
Future plans call for revising the ITRON product registration system, making provision of filled-in checksheets a requirement when registering µITRON3.0 implementations.
The seminar program is outlined below. Since this was the first ITRON presentation in China, the aim was to provide a comprehensive overview of themes relating to the ITRON specifications.
The presentation on ITRON specifications was given at the special RTOS (Real-Time Operating System) Symposium on November 9, at the Sunshine City Prince Hotel. The speaker was Toshiba's Kiichiro Tamaru, chairman of the ITRON Technical Committee, who was a featured presenter at the symposium. Speaking on "Embedded system environments and real-time OS trends - centering on the ITRON specifications," Mr. Tamaru first noted problem areas with current small-scale embedded systems. He outlined the design principles of the µITRON specifications and updated their status today. His talk also covered µITRON-specification kernel implementation techniques and looked at the future outlook for the project. The symposium was attended by approximately 550 persons, far exceeding the original plans to accommodate 250 attendees. It offered a good opportunity to publicize the ITRON specifications.
At TRONSHOW '95 on November 29, preceding the conference and held at the Tokyo Design Center in Shinagawa Ward, the University of Tokyo's Hiroaki Takada gave a presentation on behalf of the ITRON Technical Committee, on "The latest news on the ITRON real-time OS for embedded systems." He began with a brief outline of the ITRON specifications, then introduced the Technical Committee's efforts to publicize the specifications overseas, and talked about the µITRON3.0 compatibility checksheets.
