Just a note from Camille: All of the following CSVs are now ready in DEV5.

Some notes about where language related to the geography changes are going to be required for the 4.9.0 schema update. Please add other language changes as needed:

• https://lehd.ces.census.gov/data/schema/latest/lehd_shapefiles.html#_sources. Are we using 2021 TIGER as the source for all of these shapefiles? I can't remember why we used 2019 CBSA for 4.8.1. Jody, do you?
• Mention changes in 4.9.0 to both https://lehd.ces.census.gov/data/schema/latest/lehd_shapefiles.html#_changes and https://lehd.ces.census.gov/data/schema/latest/lehd_public_use_schema.html#_changes
• https://lehd.ces.census.gov/data/schema/latest/lehd_public_use_schema.html#_geography. Update last sentence to reflect 2021 TIGER as of R2022Q2.
• I don't believe there are any other changes required, as there shouldn't be any structural changes to how geography is explained in the schema. Once all of the CSVs and shapefiles are saved to https://lehd.ces.census.gov/data/schema/V4.9.0/, the remaining geography subsections won't need any language changes.

Yeah, it'll be TIGER 21. I can't remember what the exact reason for 2019 CBSAs was but we punted due to some data mismatch and used the old version.

We unified the changelog into one long running document which is handwritten. https://ledapplications.github.io/lehd-schema/lehd_changelog.html which can be edited directly here: https://github.com/LEDApplications/lehd-schema/blob/main/src/lehd_changelog.asciidoc

Updated https://github.com/LEDApplications/lehd-schema/blob/main/src/lehd_public_use_schema.asciidoc and https://github.com/LEDApplications/lehd-schema/blob/main/src/lehd_shapefiles.asciidoc. I'll wait to updated https://github.com/LEDApplications/lehd-schema/blob/main/src/lehd_changelog.asciidoc until we know for sure all of the changes involved in 4.9.0.

Shapefiles have been produced and will be available on dev when we begin rollout.

The first QWI in V4.9.0 was just released (not yet pushed to the web server, but I assume soon?). Can we get the schema up ASAP?
