# Change log
## 4.106.0
**Community Edition:** 2026-03-05\
**Enterprise Edition:** 2026-03-12
**Improved:**
* Generated knowledge graphs now have additional question configuration applied to improve the query experience
* Clearer error messages when generating a graph from documentation fails
* UX enhancements for Generate from Docs and Co-author
**Fixed:**
* Cancelling your request when generating from documentation now cancels correctly and displays the modal again so you can amend and resubmit.
***
## 4.105.0
**Community Edition:** 2026-02-19\
**Enterprise Edition:** 2026-02-26
**New:**
* You can now upload documents directly into Co-author to support further refinement and iteration.
**Improved:**
* When you generate a graph from documentation, your prompt and documentation is now handed over to Co-author. After generation the description of what has been built is also added to Co-author. This results in it becoming much easier to ask for changes (this change deprecates the readme being updated with a description).
***
## 4.104.0
**Community Edition:** 2026-02-05\
**Enterprise Edition:** 2026-02-12
**New:**
* The Co-author conversation history can now be cleared.
**Improved:**
* The QuickQuery panel can now be expandable if you are testing with long questions, grouped questions or large metadata and need the panel to be higher.
* Automated tester shows better inject errors. This helps users identify and fix issues with their inject tests must quicker.
**Fixed:**
* The subject dropdown on a condition has been fixed so the subject can be switched from an instance back to a variable.
***
## 4.103.0
**Community Edition:** 2026-01-22\
**Enterprise Edition:** 2026-01-29
**New:**
* A link to the new Rainbird Forum is available in the left-hand global navigation bar
**Improved:**
* Explanations of evidence are turned on by default in the Natural Language test agent.
* Co-author now formats markdown making responses easier to read
***
## 4.102.0
**Community Edition:** 2026-01-08\
**Enterprise Edition:** 2026-01-13
**Improved:**
* Rule names will now be used by Co-author when creating and updating graphs and are also now searchable in the Navigator
* Co-author now uses the context of previous messages when responding, which improves the natural conversational flow and increases the quality of its response
***
## 4.101.0
**Community Edition:** 2025-12-17\
**Enterprise Edition:** 2026-01-06
**New:**
* Rules can now be given optional, human-readable, names. These make knowledge graphs easier to understand, validate and maintain. Learn more about [named rules](https://docs.rainbird.ai/rainbird/whats-new/named-rules).
**Improved:**
* Expressions containing calculations within brackets were restricted to one operator e.g. `(2 + 2)`. This required users to refactor their calculations before they could be saved . Calculations within brackets can now contain more than one operator e.g. `(2 + 2 + 2)`. This provides more flexibility and easier authoring. **Please note:** calculations process from left-to-right, rather than following the PEMDAS/BODMAS standard, so it remains important to pay attention to the order of operations.
***
## 4.100.0
**Community Edition:** 2025-12-04\
**Enterprise Edition:** 2025-12-10
**Improvement:**
* [Generate from Docs](https://docs.rainbird.ai/rainbird/rainbird-labs/generate-from-documentation) can be accessed from the new map page as well as the files page.
***
## 4.99.0
**Community:** 2025-11-19\
**Enterprise:** 2025-11-26

***
## 4.98.0
**Community:** 2025-11-11\
**Enterprise:** 2025-11-18
**New:**
* A set of tools to accelerate knowledge graph builds and to test natural language queries have been released as open beta.
* [**Generate from documentation**](https://docs.rainbird.ai/rainbird/rainbird-labs/generate-from-documentation) - Create Rainbird knowledge graphs from prompts and business documentation such as policies and regulations, accelerating the build process and reducing manual effort.
* [**Co-author**](https://docs.rainbird.ai/rainbird/rainbird-labs/co-author) - an AI-powered assistant for accelerating knowledge graph refinement. Give co-author instructions on what you would like to be updated before reviewing and testing these changes.
* [**NL test agent**](https://docs.rainbird.ai/rainbird/rainbird-labs/nl-test-agent) - test our natural language APIs ([/interact ](https://docs.rainbird.ai/rainbird/rainbird-labs/interact) & [/explain](https://docs.rainbird.ai/rainbird/rainbird-labs/explain)) directly from the Studio. Provide unstructured data and a query, answer any questions the reasoning engine has and get a result, complete with a natural language explanation of the evidence tree.
**Fixed:**
* Using double-quotation marks `"` in your knowledge graph (e.g. in concept, instance or relationship names) will display a validation error to prevent breaking the underlying RBlang.
***
## 4.97.0
**Community:** 2025-10-23\
**Enterprise:** 2025-10-30
Not much to report as we're busy working behind the scenes.

***
## 4.95.0
**Community:** 2025-09-25\
**Enterprise:** 2025-10-02
**New:**
* `regexCount()` function added to allow flexible pattern matching in a string. This enables checks to be performed and inferences made where the data is less structured. This reduces requirements to pre-process data before injecting it into a knowledge graph, managing checks with complex logic in the graph or relying on external datasources to perform regular expression checks. [Find out more about regexCount](https://docs.rainbird.ai/rainbird/knowledge-modelling/modelling-features/relationships/rules/expressions-list#regexcount).

***
## 4.92.0
**Community:** 2025-08-18\
**Enterprise:** 2025-08-26
**New:**
* `joinObjects()` function added to join a list of objects from a plural relationship into a single comma-separated string. This function helps to to build string concatenated results when you want to list a set of instances in the result text (e.g. "Option A is recommended, but the following decisions were also considered: B, D, F."). More details can be found [here](https://docs.rainbird.ai/rainbird/knowledge-modelling/modelling-features/relationships/rules/expressions-list#joinobjects).
**Fixed:**
* A concepts list of instances doesn't reset itself to the original order when a user reorders an already re-ordered list.
***
## 4.91.0
**Community:** 2025-07-30\
**Enterprise:** 2025-07-31
**New:**
* Expression functions called `startsWith()` and `endsWith()` . These enable new facts to be inferred when a string starts with or ends with a specified set of characters. E.g. A postcode that starts with NR is likely in the Norwich area. More details can be found [here](https://docs.rainbird.ai/rainbird/knowledge-modelling/modelling-features/relationships/rules/expressions-list#startswith).
***
## 4.90.0
**Community:** 2025-07-21\
**Enterprise**: 2025-07-24
**New:**
* Expression functions called `subtractDays()`, `subtractWeeks()`, `subtractMonths()` and `subtractYears()`. Previously this could be achieved with the add functions (e.g. `addDays()`) by using a negative number, but the new functions are more intuitive to model and clearer in evidence. More details can be found [here](https://docs.rainbird.ai/rainbird/knowledge-modelling/modelling-features/relationships/rules/expressions-list#add-or-subtract-from-a-date).
* Facts that contributed to a list function are now returned in evidence and displayed in the evidence tree. This provides much greater explainability and traceability when these functions are used. [Learn more about list function fact cards.](https://docs.rainbird.ai/rainbird/evidence/the-evidence-tree#list-function-fact-card)
**Fixed:**
* Using dates within evidence alt-text will now display in our supported format of YYYY-MM-DD, rather than a timestamp.
* Variables are now available in the expression auto-complete tool.

***
## 4.88.0
**Community:** 2025-06-18\
**Enterprise**: 2025-06-25
**New:**
* New expression function called `isWithinRange()` introduced to check if a date or number is within the specified range. This is a more efficient way to express this logic compared to previous expressions. Instead of `(%AGE is greater or equal to 18) and (%AGE is less than or equal to 30)` you could now use `isWithinRange(%AGE, 18, 30)`. More details can be found [here](https://docs.rainbird.ai/rainbird/knowledge-modelling/modelling-features/relationships/rules/expressions-list#iswithinrange).
**Fixed:**
* Using dates within a string concatenation will now display in our supported format of YYYY-MM-DD, rather than a timestamp.
* Relationship names used in expressions and enclosed in 'single quotes' will now correctly update if the relationship name is changed.
* Rearranging rules, conditions or instances will no longer cause text to become highlighted.
***
## 4.87.0
**Community:** 2025-06-10\
**Enterprise**: 2025-06-17
#### **Improved:**
* When writing an expression with and/or logic, only lowercase `and` / `or` was allowed. We've relaxed this so uppercase (`AND` / `OR`) and sentence case (`And` / `Or`) are allowed.
***
## 4.86.0
**Community:** 2025-05-22\
**Enterprise:** 2025-05-28
#### Improved:
* The default layout of the graph has been improved for large maps generated via Co-author or when RBLang is pasted into a new file.
**Fixed:**
* Concept instance names referenced in expressions will be automatically updated if the instance name is changed. This problem was specific to expressions that contained references to multiple concept instances.
***
## 4.85.0
**Community:** 2025-05-19\
**Enterprise:** 2025-05-21
**New:**
* New expression function called `includes()`. Rules can now be written based on partial string matching. More details can be found [here](https://docs.rainbird.ai/rainbird/knowledge-modelling/modelling-features/relationships/rules/expressions-list#includes).
* Navigate back to your maps sub-folder from the Studio editor using the new back button.
**Fixed:**
* Queries resulting in over 65,000 facts contained missing facts in the evidence.
***
## 4.84.0
**Community:** 2025-04-25\
**Enterprise:** 2025-05-01
**New:**
* New expression function called `maxObjects()` introduced to find the highest value in a list of dates or numbers. More details [here](https://docs.rainbird.ai/rainbird/knowledge-modelling/modelling-features/relationships/rules/expressions-list#maxobjects).
***
## 4.83.0
**Community:** 2025-04-10\
**Enterprise:** 2025-04-16
**New:**
* New expression function called `minObjects()` introduced to find the lowest value in a list of dates or numbers. More details [here](https://docs.rainbird.ai/rainbird/knowledge-modelling/modelling-features/relationships/rules/expressions-list#minobjects).
* A Consult report can now be downloaded as a PDF.
**Fixed:**
* When selecting new expression, the expression input now has focus so you can type straightaway without manually clicking into the input.
* The expression auto-complete works correctly if you searched with an apostrophe `'`already at the start of the relationship or instance name.
* In interaction history, the second date in the answer of a grouped question no longer displays as a timestamp.
**Removed:**
* Beta data extract feature removed from the Studio.
***
## 4.82.0
**Community:** 2025-03-26\
**Enterprise:** 2025-04-02
