There are two documents relevant to data previews and releases :
Rubin Observatory Plans for an Early Science Program (Leanne Guy et al. RTN-11), latest version is dated 10th Feb 2023.
“Release Scenarios for Rubin - LSST Commissioning and Survey Data” (Phil Marshall et al. RDO-11) lates latest version is dated 7th August 2022. Rubin Observatory Plans for an Early Science Program (Leanne This is now well out of data and redundant, until a new version is released, we should focus on the Guy et al. RTN-11 ), latest version is dated 1st January 2023
DR1 is projected to be November 2025.
Note the calendar years start at the dotted lines (US financial years are solid lines, starting October)

Very Important note : on 23rd November 2022, the project released an update on the Construction Plan. On-sky data with ComCam will NOT be taken, and the project is planning on installing LSSTCam on the telescope earlier than in the assembly sequence. The projected start of operations of October 2024 has not changed. It is anticipated that LSSTCam will now be ready to take on-sky data at the time when ComCam was due to do so (end of 2023, although that needs confirmed). The DP1 and DP2 plans in the above data schedule will change and a status report will be giving at the AAS January 2023 meetinghave changed.This is generally good news as on-sky commissioning with ComCam (1/12 of the CCDs rafts) will be replaced with on-sky commissioning with LSSTCam, expanding the possibility for early science (see draft document Rubin Observatory Plans for an Early Science Program )..

System First Light : a milestone that marks the end of the on-sky engineering phase
System optimisation and Science Validation phase : a period of about 4 months after System First Light
Start of LSST Science operations : projected about 4 months after System First Light and after the Science Validation phase has been successfully completed

Details of what will be included in the data releases
As noted above DP1 and DP2 will be revised such that there will be no on-sky data with ComCam, and the project will move more quickly to LSSTCam on-sky data. A revised Marshall et al. document all be released in 2023.
