Pathfinder Release Notes

The following sections list every released version of Pathfinder, newest first. Each section comes from the monthly OCP® Release Notes page named in its Released line.

Pathfinder 1.9.8

Released: November 2026

New Features

• Knowledge Base Search Index for Partial or Misspelled Names — Large document-based knowledge bases, such as a list of hotels, can now be searched by a partial or misspelled name instead of requiring an exact match. A new "Search index" view lets you upload a list of names and details, track processing status, test a search, and remove the index when it's no longer needed. The underlying search returns ranked matches with a confidence score, asking for more details only when several entries match equally well.

• Adjustable Match Strictness for Knowledge Base Search — Knowledge base projects can now set their own match strictness — Strict, Balanced, or Lenient — directly in Project Settings. This lets you decide whether search results must match closely or return broader context, without needing to tune it on every request.

Fixes

• More Reliable Conversations During Multi-Turn Search — When the AI service that rephrases follow-up questions is slow or unavailable, search now automatically falls back to your original question instead of stalling, keeping multi-turn conversations responsive.

• Fewer Failed Document Uploads — Documents and web pages occasionally failed to process because of temporary connection issues reaching the encoding service. These are now automatically retried, so more uploads succeed without manual re-processing.

• Correct Inline Display for Certain PDFs — Some PDF documents in the knowledge base viewer downloaded instead of opening directly in the browser. They now display inline as expected.

• Accurate Search After Rolling Back an FAQ Document — Rolling back a frequently-asked-question document to an earlier version used to make its answer disappear from search results. Search now continues returning the correct answer after a rollback.

Pathfinder 1.9.7

Released: October 2026

Fixes

• More Reliable Document Search and Version History – Searching knowledge base documents by multiple metadata filters at once now correctly returns only documents that match every filter, not just the last one applied. Document version history is also preserved more reliably, so earlier versions of updated documents remain retrievable.

• More Consistent Knowledge Base Search Results – Searching the knowledge base now returns the same, most relevant answers consistently for identical questions, and surfaces all matching documents instead of occasionally missing the best match. This improves answer accuracy and reliability for repeated or similar questions.

• Faster Recovery From Temporary AI Service Issues – Chat responses now fail fast when a genuine configuration issue occurs instead of waiting through repeated retries, and recover more quickly from brief service hiccups, reducing wait times during occasional disruptions.

• This release includes security updates.

Pathfinder 1.9.6

Released: September 2026

Fixes

• Improved Reliability During Peak Call Volume - Under heavy call volume, a background knowledge-base maintenance task sometimes slowed shared platform resources, causing intermittent call connection delays. This maintenance now runs safely, so call handling stays reliable even during busy periods.

Pathfinder 1.9.5

Released: September 2026

New Features

• Smarter Knowledge Base Search for Follow-Up Questions – When your virtual agent asks a clarifying question and the caller replies briefly (e.g. "yes"), the knowledge base now understands the original question behind that reply and searches for it. This improves answer accuracy across multi-turn conversations, with no change to single-question searches.

Improvements

• Clearer Resource Ingestion Failure Reasons – When a document, URL, or file fails to be added to your knowledge base, you now see a more specific reason for the failure instead of a generic message, making it easier to identify and resolve the issue.

Pathfinder 1.9.4

Released: August 2026

Improvements

• Faster Response Times During High-Traffic Periods - Response times stay consistently fast during bursts of heavy concurrent usage, so authentication, search, and retrieval actions remain smooth even at peak load.

Pathfinder 1.9.3

Released: July 2026

Fixes

• Restored Functionality for Imported RAG Applications - Applications using online and offline Retrieval-Augmented Generation (RAG) that were exported and re-imported would fail with a "No vector stores found" error when queried. This is now resolved, and imported RAG applications respond correctly.

• Reliable Service Account Authentication - Requests authenticated with a Service Account were returning an internal server error when performance monitoring was enabled. This is now resolved, and Service Account-authenticated requests are handled correctly in all configurations.

Pathfinder 1.9.2

Released: June 2026

New Features

• Plain-Text Document Support in Knowledge Base Projects - Knowledge base document-retrieval projects now accept plain-text (.txt) files in addition to JSON. You can upload .txt documents directly to your project, and retrieval results include the text content alongside a content type indicator, making it easier to work with a wider range of document formats without manual conversion.

Fixes

• Reliable Project Import - The Import button is now disabled immediately after you click it when creating a project from an exported file, preventing accidental duplicate imports.

• Clearer, safer error messages when uploading invalid or corrupt documents.

• Security and dependency hardening, including an updated authz-sidecar.

Pathfinder 1.9.1

Released: June 2026

• Compatibility fix

Pathfinder 1.9.0

Released: June 2026

What's New

• Faster, more reliable project exports. Exporting a project no longer blocks or times out on large knowledge bases - exports run in the background. Track progress and download when ready, with a real download progress bar, and re-download the archive anytime until it expires. You'll be notified when your export is ready. Exports now also include the knowledge-base metadata-field schema.

• Personal Access Token (PAT) authentication. Authenticate API requests with a Personal Access Token, in addition to standard bearer tokens.

• Filter knowledge-base documents by filename. Quickly find documents by searching on their filename.

Improvements & fixes

• Knowledge-base search now reflects paraphrase edits immediately instead of after a delay.

• Clearer, safer error messages during document ingestion.

• Reliability and security hardening across export and authentication.

• Import ZIP file size limit increased to 200 MB. For more information go to Pathfinder User Guide.

Pathfinder 1.8.9

Released: May 2026

What's New

• Project Export & Import - Move projects between environments or duplicate them with one click. You can now:

  • Export a project - download a single archive containing all intents, utterances, answers, facts, resources, Knowledge Base documents, and search index data.

  • Import as a new project - create a fresh project from an archive in one step.

  • Merge into an existing project - combine an archive with an existing project of the same type, adding its content without overwriting.

Export and import actions appear in the project row menu and the New Project dialog. Access is controlled by feature flag and role permissions, and every export/import is recorded in the audit trail. For more information, see Project Import & Export.

• Refreshed Look - The interface has been updated to use a unified design system, giving a more consistent experience across screens. Header and accent colors are corrected.

Fixes

• The Import button now stays disabled while a merge is in progress, preventing accidental duplicate submissions.

• After a successful import or merge, Go to Project lands you directly in the journey mapper.

• The New Project dialog renders correctly when switching to import mode.

• Export failures now surface a clear error message instead of failing silently.

Security

• Upgraded an internal networking dependency to address a published vulnerability (CVE-2026-45736). No customer action required.

Pathfinder 1.8.8

Released: May 2026

Improvements

• Faster and more reliable ZIP batch uploads.

• Large ZIP archives with multiple FAQ PDF files now process reliably without timeout errors. All documents are queued and processed in the background; track progress directly from the knowledge base document list.

• Guided project creation.

• Creating a new project now walks you through a step-by-step wizard with live progress updates during ingestion. A "Go to project" button at the end takes you straight to the new project once it's ready.

• See why a document failed without opening it.

• Documents in a Failed or Error state now show the failure reason directly as a tooltip on the status badge. No need to click into the document detail page to diagnose what went wrong.

• Find documents faster with the Document ID column.

• The knowledge base document list now has a dedicated Document ID column, making it easy to copy a UUID for API calls, logs, or support requests.

• Cleaner document list.

• Documents now display their display name as the primary label, with the raw filename shown below as secondary text - easier to scan at a glance.

• Upload mode is now a clear card-based selection.

• When uploading to a Chunk Retrieval project, Standard and FAQ PDF ingestion modes are shown as cards with descriptions. FAQ PDF is selected by default.

Bug fixes

• Failed documents now show the correct error reason immediately, without needing to refresh the page.

• Status tooltips now display correctly inside modals and dialogs.

• No more spurious "request timed out" notifications when a document has already finished processing.

• Knowledge base dropdown menus now appear correctly over modal overlays.

Pathfinder 1.8.7

Released: April 2026

New Features

• Knowledge Base - FAQ PDF Ingestion
  Pathfinder now supports a dedicated ingestion mode for structured PDF documents. When you upload a PDF as an FAQ document, the content is automatically processed into distinct Q&A entries - each with a canonical question and a set of answer paraphrases - rather than raw text chunks. This makes retrieval more accurate for document-heavy knowledge bases and gives you fine-grained control through an inline review and approval workflow before content goes live.

• ZIP Batch Upload for Knowledge Base Documents
  You can now upload a ZIP archive containing multiple PDF files in a single operation. All documents in the archive are ingested asynchronously and appear in your knowledge base list once processing is complete.

• Publish All Documents
  A new Publish All button on the Knowledge Base page lets you bulk-publish all approved documents at once, removing the need to publish each entry individually.

• Inline PDF Viewer
  When reviewing a knowledge base document, a new Document tab displays the original PDF directly within the page, so you can cross-reference source content while managing entries and paraphrases.

• New Knowledge Base Type for QnA Agents - Chunk
  QnA agents now support a third knowledge base configuration type: chunk. In addition to the existing document type (project ID + input schema) and rag type (project ID + vector store), the new chunk type requires only a project ID - making it faster and simpler to connect a chunk-based knowledge source without additional schema or vector store configuration.

• Vector Store Index Management
  A dedicated Manage Indexes page is now available for each project, giving you visibility into the state of your vector store indexes and a centralised place to manage them.

• Updated Embeddings Service
  The underlying embeddings service has been updated to improve vector quality and retrieval accuracy across all knowledge base projects.

• Claude 4 Model Support
  Pathfinder now supports Anthropic's Claude 4 model family via AWS Bedrock. You can select Claude 4 models in your project-level LLM settings without any additional configuration changes.

Security Improvements

User email addresses and usernames are now automatically redacted from system logs and audit events in production environments, while user IDs are retained for support and correlation purposes. This ensures sensitive personally identifiable information is not exposed in operational logs.

Bug fixes

• Knowledge base documents uploaded as a ZIP batch are now correctly tagged with the right ingestion type.

• PDF documents now render inline in the document viewer instead of triggering a download.

• The knowledge base upload status indicator now correctly reflects progress for batch (FAQ PDF) ingestion jobs.

• Pathfinder workers now shut down cleanly without dropping in-flight tasks.

Pathfinder 1.8.5

Released: April 2026

Knowledge Base Management

You can now upload and manage your own documents directly within Pathfinder:

• Upload documents (PDF, DOCX, TXT, CSV) to any project - they are automatically processed and indexed for search.

• Intelligent hybrid search across your documents combining semantic understanding with keyword matching for more accurate results.

• Review and approve content - after ingestion, review, edit, and approve individual chunks before they go live.

• Document versioning - compare revisions and roll back to a previous version if needed.

• Custom metadata fields - define project-level metadata (e.g., department, category, effective date) to organize and filter documents.

• Per-project configuration - enable/disable Knowledge Base and choose retrieval modes per project.

  

Improvements

• Service accounts can now correctly access the projects endpoint, improving automation and API integration workflows
