The technical specifications (TS) are displayed in blue, while the reports (TR) are shown in green.  TS that have been discontinued in earlier releases are indicated with a light blue color.  TR in the '9' range that have been stopped are highlighted in light green.  TS or TR with a yellow background indicate those updated (other than an automatic update to Rel-18 version after Rel-18 stage 3 freeze) at the latest  Q1-2024  Plenary Meetings.  The new ones are displayed with a single red dotted overline.
