Download all TESS Data Release Notes. The format of the files includes a sector number or range, a data release number ("drn??") that increases with every new Data Release Note and is thus a chronological indicator, and a version number ("v??") in case a given data release note needs to be replaced to fix something.
Note that for multi-sector data release notes, an additional file, called a "target info table", is included in text format. This file contains the set of TESS targets that were searched as part of multi-sector searches, and some additional information on each target's TCE and DV status as part of the run. See the header of the text files for more info.
