Changelog & Upgrades
Updates to the Nabla Core API — including new features, fields, or endpoints — are released under a new dated version to ensure stability and predictability. This means your integration won’t be affected by these changes unless you explicitly opt into the newer version (see Targeting a specific version).
That said, some updates — like internal AI models improvements, bug fixes, or strictly non-breaking changes that don’t affect the schema or observable behavior — may be rolled out across all versions.
Below is a list of all available Core API versions, along with their associated changes.
2025-08-05​
- Add new optional input field for all note generation endpoints:
structured_context: Structured context about the patient and the encounter, which will be taken into account when generating the note. Currently only includes:active_encounter_diagnoses_coding: The ICD-10 coding for the patient's active encounter diagnoses. If the template used for the note generation contains anASSESSMENT_AND_PLANsection, these diagnoses will be used for the "by problem" structuration of this section if they are discussed during the encounter.
- Added a new
active_encounter_diagnoses_codingparameter to/generate-normalized-data. If related diagnoses are found in the input note, the call will return in priority the codes passed.
2025-07-24​
- Remove
suggested_dot_phrasesfrom response of/generate-notein Server API as it has always been null (Dot Phrases are only applicable for User API). - Add new CRUD endpoints to manage Dictation Text Replacements for a user.
- Extend support for per-section customization options to note generation in French. This change applies to all prior versions too.
- Add new optional
text_field_contextproperty to dictation WS config to improve dictation quality by providing initial text context.
2025-05-21​
- Add new boolean fields
is_hccandis_mccto the FHIR condition objects returned by the/generate-normalized-dataendpoint.
2025-05-07​
- Change the dictate WebSocket protocol.
The WebSocket dictation protocol evolves to a faster and simpler model, where small units of text —such as individual words, short phrases, or punctuation marks— are sent once and don’t require any further updates.
Clients are expected to append each received unit in order, without inserting spaces or applying any formatting.
This change introduces the following breaking changes.
- Evolution of configuration options in
CONFIGframe.- The
dictate_punctuationfield has been renamed topunctuation_modeand is now an enum, with currently one possible value:EXPLICIT. - The
speech_localefield has been renamed todictate_localeand is reduced to the five following locales:ENGLISH_US,ENGLISH_UK,SPANISH_ES,SPANISH_MXandFRENCH_FR. - The
enable_audio_chunk_ackoption has been removed, since audio acknowledgement is now always activated.
- The
- Simplification and renaming of
DICTATION_ITEMframe:- The
DICTATION_ITEMframe type has been renamed toDICTATED_TEXT. - It has been simplified and now contains only a string
textproperty. - Fields
id,is_final,start_offset_msandend_offset_msproperties have been removed since dictated texts are now necessarily final and are returned in chronological order.
- The
- Evolution of configuration options in
- Add new
code,nameandtrace_idfields in WebSockets error frame JSON body. Also, themessagefield formatting changed (reminder: do not rely on this formatted string but only on the numericcode).
2025-05-05​
- Add new
corresponding_note_problemin the conditions returned by/generate-normalized-dataendpoint. Use theinclude_corresponding_note_problemsflag in the input body to enable this feature.
2025-04-03​
- Enforce a limit of 700 on the length of the custom instructions per section for note generation endpoints
- Add new User API endpoints to allow users to configure and persist their note generation preferences:
GET /note-settings— Retrieve the user’s preferred locale and template. Default values:note_locale = ENGLISH_US,note_template = GENERIC_MULTIPLE_SECTIONS.PATCH /note-settings— Update the user’s preferred locale and template.GET /note-settings/note-sections-customization/:note_template— Retrieve the default per-section customization options for a specific template.PATCH /note-settings/note-sections-customization/:note_template— Update the default per-section customization options for a specific template.
- Change in User API
/generate-noteand/generate-note-asyncendpoints:- The following fields have been removed from the request body:
