+# 2.3.0
+
+### Features:
+- **Change:** The video relevance score formula has been updated. Now `Video.publishedBeforeJoystream` can be taken into account when calculating the value of the `newness` parameter. The new formula for `newness` is:
+ ```
+ -(dsPOJ * jcw + dsPBJ * ycw) / (jcw + ycw)
+
+ Where:
+ dsPOJ - days since published on Joystream (Video.createdAt)
+ jcw - joystream creation weight
+ dsPBJ - days since published before Joystream (Video.publishedBeforeJoystream)
+ ycw - YouTube creation weight
+ ```
+
+### Config values:
+- **Change:** `RELEVANCE_WEIGHTS` config value now has a new format:
+ ```diff
+ [
+ 1, # newness weight,
+ 0.03, # views weight
+ 0.3, # comments weight
+ 0.5, # reactions weight
+ + [7,3] # [joystream creation weight, YouTube creation weight]
+ ]
+ ```
+ If the value of `[joystream creation weight, YouTube creation weight]` is not provided, it is set to `[7,3]` by default.
+
+### Schema/API changes:
+- **Change:** `setVideoWeights` operator mutation now accepts 2 new arguments: `joysteamTimestampSubWeight` and `ytTimestampSubWeight`
+
+### Mappings:
+- `videoRelevanceManager` is now used in `processVideoCreatedEvent` to calculate `videoRelevance` (to avoid code duplication)
+
+### DB Optimalizations:
+- Changes in `postgres.conf` to improve query execution time in current production deployments:
+ - Turn off JIT compilation which was usually uneffective
+ - Lower `random_page_cost` to `1.0`, as the database still fits into the memory
+ - Increase `shared_buffers` to `2GB` 
+- New indexes added to `db/migrations/2100000000000-Indexes.js` (`auction_type`, `member_metadata_avatar`, `owned_nft_auction`)
+
+### Fixes:
+- `scripts/generate-schema-file.sh` has been made executable w/o bash to avoid error during docker build
+- The issue w/ _Offchain State_ not being imported if the `export.json` contained empty `update` tables (an error was thrown in this case) has been fixed
