On 23rd November 2022, the project released an important 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 have changed.This is generally good news as on-sky commissioning with ComCam will be replaced with on-sky commissioning with LSSTCam.

Useful definitions :
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
In the above schedule, DP1 (the first real LSSTCam data products) is DP1, but it will only have a very small subset (a few nights) of the early commissioning data.
DP2 will have full reprocessed data but only data from the Science Validation phase.
DR1 will have the first 6 months of science survey data included and will have completely processed data. It will be released 1 year after the start of the science survey.
