// HOW THIS ISSUE IS MADE

We read every release from the 174 tools on our watchlist at the source — GitHub and GitLab release notes, vendor release pages and changelogs, project blogs and feeds, vendor press releases, and the source code behind the tag. Bug-fix-only releases and non-product newsroom noise are dropped; what's left is summarized down to the new capability, how to try it, and any screenshots or videos the release itself published. Every entry links to the sources it was built from.

0.22.7 3 RELEASES · 2020-04-01 → 2020-04-29 NOTES STABLE

Weaviate 0.22.7 rewrites contextual classification with Information Gain and tf-idf weighting, lifting accuracy from 18% to 58% on main categories.

└──▷ GET THIS VERSION

$ git clone --branch 0.22.7 https://github.com/weaviate/weaviate.git
# already have the repo? check out this version:
$ git checkout 0.22.7

└──▷ USE IT

Tune contextual classification to reduce stop-word noise on a long-text corpus by setting Information Gain and tf-idf cutoffs.

yaml

type: contextual
informationGainCutoffPercentile: 10
informationGainMaximumBoost: 3
tfidfCutoffPercentile: 80

›Rewrites the contextual classification algorithm using two new user-configurable metrics — Information Gain and tf-idf — to down-weight stop words and filler words; benchmark on the 20 Newsgroups dataset shows main-category success rate rising from 18% to 58% and granular-category (20 classes) from 10% to 42%.
›Adds informationGainCutoffPercentile, informationGainMaximumBoost, and tfidfCutoffPercentile configuration parameters to the contextual classification to let practitioners tune word-weighting and removal thresholds for their dataset.

0.22.6 NOTES STABLE

Weaviate 0.22.6 adds reference-count filtering so you can query objects by how many linked references they have.

└──▷ GET THIS VERSION

$ git clone --branch 0.22.6 https://github.com/weaviate/weaviate.git
# already have the repo? check out this version:
$ git checkout 0.22.6

›Enables filtering objects by the count of their references using existing compare operators (Equal, LessThan, LessThanEqual, GreaterThan, GreaterThanEqual) directly on a reference path in GraphQL where filters — supporting queries like 'find all authors who wrote at least 2 articles' or 'show all cities with no country association'.

0.22.5 NOTES STABLE

Weaviate 0.22.5 adds navigable API root with hypertext links and cross-reference href fields across REST endpoints.

└──▷ GET THIS VERSION

$ git clone --branch 0.22.5 https://github.com/weaviate/weaviate.git
# already have the repo? check out this version:
$ git checkout 0.22.5

›The / path now redirects (301 Moved Permanently) to /v1, and /v1 returns a JSON list of main API categories with documentation links instead of 404 Not Found.
›Adds an origin config option: when set, all root and cross-reference hyperlinks are rendered as absolute URIs, enabling correct link generation behind a reverse proxy; when unset, relative links are used.
›All REST endpoints that return cross-references now include a read-only href field alongside the existing beacon field, providing an HTTP hypertext reference to the respective resource.
