Delta Lake Public Preview
There are multiple references on this page to delta lake aspects being in public preview.
However, the official page at https://learn.microsoft.com/en-us/azure/synapse-analytics/sql/query-delta-lake-format makes no reference to the public preview status.
Can you please clarify this aspect? Is the page out of date and is the feature now GA? Or is there a mix of related features, with some GA and some still in public preview?

@VitalyMCT Thanks for your feedback! We will investigate and update as appropriate.
@VitalyMCT
Thank you for your time and patience! Unfortunately, we don't provide product release updates through our GitHub channels. For this, I'd recommend referring to our Azure Updates or Microsoft 365 Roadmap pages for this info.
This is not a request for "product release updates".
This is a request to rectify the correctness of documentation. Please review the ticket details.
@VitalyMCT I'm going to assign this to the document author so they can take a look at it accordingly.
@azaricstefan Can you please check and add your comments on this doc update request as applicable.
@AjayBathini-MSFT document is up to date. These features inside Delta Lake tables are still in Public Preview.
@azaricstefan In that case would the main official page be updated accordingly? Please see note at the beginning of the ticket.
It's a incredibly confusing to the reader (almost impossible, in fact) to figure out what's in public preview and what's in GA for delta lake based on these 2 pages. It seems that support in serverless SQL pools may be GA, whereas support in lake databases may be in public preview, but again, that's quite unclear.
I would encourage Microsoft to review both pages from customer perspective and adjust as required.
Hi @VitalyMCT I followed up with a colleague and we updated the docs and added note: "Querying Delta Lake format using the serverless SQL pool is Generally available functionality. However, querying Spark Delta tables is still in public preview and not production ready. There are known issues that might happen if you query Delta tables created using the Spark pools. See the known issues in the self-help page.".
Ok. Is that update done in a different (internal) system? It's not on GitHub:
@VitalyMCT now it is public: https://learn.microsoft.com/en-us/azure/synapse-analytics/sql/query-delta-lake-format
