Should we mention the OSM stuff in the bugfixes area? I'd say no.
Also there is a lot of stuff that is not a feature in the features section. E.g. "Using copy protocol in row-by-row fetcher", this is not in user terms and not a feature, I would mention it in the Improvements section as "Performance of bulk SELECT and COPY is improved for distributed hypertables", and this would include the "non-blocking connections for COPY".

i'll doublecheck with gayathri regarding osm stuff |
Yes, I think these are internal changes and we don't have to mention those. |

I would be more explicit about the new functions:
#4563 Experimental functions to facilitate Continuous Aggregates policies management:
alter_policies,remove_policies,remove_all_policies,show_policies
| * time_bucket now supports bucketing by month, year and timezone | ||
| * Improve performance of bulk SELECT and COPY for distributed hypertables | ||
| * 1 step CAgg policy management | ||
| * Migrate Continuous Aggregates to the new format |

Should we add the name of the new function introduced to migrate: cagg_migrate_to_finals_form ?
| * #4415 Drop remote data when detaching data node | ||
| * #4416 Handle TRUNCATE TABLE on chunks | ||
| * #4425 Add parameter check_config to alter_job | ||
| * #4430 Create index on Continuous Aggregates |

Does it impact performances? we may want to highlight this.

I just wondered what the state of 2.8.0 is. I see that this PR was closed two weeks ago, and the corresponding tag is available on github. So from that perspective, it looks like this is the final 2.8.0 release. However, there are no release notes about 2.8.0 on https://docs.timescale.com/timescaledb/latest/overview/release-notes/. Because of this I'm a bit unsure and that keeps me from updating to 2.8.0 ;) |
|
Hmm i can see release notes for 2.8.0 on that page. |
|
Now that is what I call a caching issue. I had to reload with cold caches to see them. On the other hand, I am also subscribed to the "Product Updates & Release Notes subscriber list" but did not see an email either. But maybe I was too late with my subscription, as I subscribed on the very same day as 2.8.0 was released. Thanks anyway! |
