## Executive Summary (TL;DR)
Meilisearch v1.3.0. Source highlight: Meilisearch v1.3.0 introduces vector search, visible ranking score details, and the possibility to define fields to search on at search time. It also now includes the ability to search within facet values and sort facet values by count.

## New Features
- Improve the Prometheus `/metrics` experimental feature (#625). Provides metrics on the task queue such as the number of queued tasks and the number of processing tasks. Adds the real database size used by Meilisearch. Add "meilisearch" prefix to metrics. Exposes `lastUpdate` and `isIndexing` in` /stats` endpoint (#3789, #3861, #3851) @irevoire @dureuill @gentcys
- Add new `/experimental-features` endpoint to configure `scoreDetails` and `vectorStore`  (#3850) @dureuill
- Add a cron test with disabled tokenization (with @roy9495) (#3779) @curquiza
- Add more documentation to graph-based ranking rule algorithms (#3835) @loiclec

## Improvements
- Enhance Japanese word segmentation (#218) @mosuka
- Enhance separator-based Tokenization (#215) @ManyTheFish
- words containing `_` are now properly segmented into several words
- brackets `{([])}` are no longer considered as context separators for the `proximity` ranking rule
- Reduce index size (~15%) by removing an internal database (#3819) @loiclec
- Reduce deserialization time by using `RoaringBitmap::deserialize_unchecked_from` (#3788) @Kerollmops

## Bug Fixes
- Fix matching results returned by the `exactness` ranking rules when there are hard separators present (#3824) @dureuill
- Fix an issue where searching for words without `.` doesn't match any string in the index (#151, #3778)
- Fix case-sensitive search result issues with camelCasing. For example, a search for `dellonghi` would previously not return a document with `DeLonghi` in it. This deactivates camel case segmentation that was introduced in v1.2.0 (#3921) @ManyTheFish
- Fix an issue around incorrect deletion of documents when using the `disableOnAttributes` typo setting  (#3819) @loiclec
- Replace the `atty` dependency with the `is-terminal` due to security vulnerability (#3878) @Kerollmops
- Fix a panic when sorting geo fields represented by strings (#3929) @Kerollmops
