| 8 | + |
| 9 | +*Sep 26, 2025* |
| 10 | + |
| 11 | +Helm Chart version: [1.11.2](https://github.com/HumanSignal/charts/blob/master/heartex/label-studio/Chart.yaml) |
| 12 | + |
| 13 | +### New features |
| 14 | + |
| 15 | +#### Annotate conversations with a new Chat tag |
| 16 | + |
| 17 | +Chat conversations are now a native data type in Label Studio, so you can annotate, automate, and measure like you already do for images, video, audio, and text. |
| 18 | + |
| 19 | +For more information, see: |
| 20 | + |
| 21 | +[**Chat tag page**](/tags/chat) |
| 22 | + |

| 26 | + |
| 27 | + |
| 28 | + |
| 29 | +### Enhancements |
| 30 | + |
| 31 | +#### One-click annotation for audio-text dialogues |
| 32 | + |
| 33 | +When labeling paragraphs in dialogue format (`layout="dialogue"`), you can now apply labels at an utterance level. |
| 34 | + |
| 35 | +There is a new button that you can click to apply the selected label to the entire utterance. You can also use the pre-configured `Command + Shift + A` hotkey: |
| 36 | + |
| 37 | + |
| 38 | + |
| 39 | +#### Adjustable height for audio players |
| 40 | + |
| 41 | +While you can still adjust the default height in the labeling configuration, now users can drag and drop to adjust the height as needed. |

| 45 | +</video> |
| 46 | + |
| 47 | +#### Support for Azure Blob Storage with Service Principal authentication |
| 48 | + |
| 49 | +You can now connect your projects to Azure Blob Storage using Service Principal authentication. |
| 50 | + |
| 51 | +Service Principal authentication uses Entra ID to authenticate applications rather than account keys, allowing you to grant specific permissions and can be easily revoked or rotated. For more information, see [Azure Blob Storage with Service Principal authentication](https://docs.humansignal.com/guide/storage#Azure-Blob-Storage-with-Service-Principal-authentication). |
| 52 | + |
| 53 | +<img style="max-width: 825px" src="/images/releases/2-29-azure.png" alt="Screenshot"/> |
| 54 | + |
| 55 | +#### Redesigned cloud storage modal |
| 56 | + |
| 57 | +When adding cloud storage, the modal has now been redesigned to add clarity and additional guidance to the process. |
| 58 | + |
| 59 | +For example, you can now preview a list of files that will be imported in order to verify your settings. |
| 60 | + |
| 61 | +<img style="max-width: 800px" src="/images/releases/2-29-cloud-storage-modal.png" alt="Screenshot"/> |
| 62 | + |
| 63 | + |
| 64 | +#### Debug custom agreement metrics |
| 65 | + |
| 66 | +There is a new **See Logs** option for [custom agreement metrics](custom_metric), which you can use to view log history and error messages. |
| 67 | + |
| 68 | +<img style="max-width: 500px" src="/images/releases/2-29-debug-metrics.png" alt="Screenshot"/> |
| 69 | + |
| 70 | +#### Nested annotator filter |
| 71 | + |
| 72 | +When applying an annotation results filter, you will now see a nested Annotator option. This allows you to specify that the preceding filter should be related to the specific annotator. |
| 73 | + |
| 74 | +For example, the following filter will retrieve any tasks that have an annotation with choice "bird" selected, and also retrieve any tasks that have an annotation submitted by "Sally Opossum." |
| 75 | + |
| 76 | +This means if you have a task where "Max Opossum" and "Sally Opossum" both submitted annotations, but only Max chose "bird", the task would be returned in your filter. |
| 77 | + |
| 78 | + |
| 79 | + |
| 80 | +With the new nested filter, you can specify that you only want tasks in which "Sally Opossum" selected "bird": |
| 81 | + |
| 82 | + |
| 83 | + |
| 84 | +#### Filter by prediction results |
| 85 | + |
| 86 | +You can now filter prediction results by selecting options that correspond to control tag values. |
| 87 | + |
| 88 | +Previously, you could only filter using an unstructured text search. |
| 89 | + |
| 90 | +The prediction results filter also includes a nested model version filter, which (if specified) will ensure that your filters returns tasks only when the selected prediction result comes from the selected model. |
| 91 | + |
| 92 | + |
| 93 | + |
| 94 | +#### Hide Data Manager columns from users |
| 95 | + |
| 96 | +There is a new project setting available from **Annotation > Annotating Options** and **Review > Reviewing Options** called **Show unused data columns to reviewers in the Data Manager**. |
| 97 | + |
| 98 | +This setting allows you to hide unused Data Manager columns from any Annotator or Reviewer who also has permission to view the Data Manager. |
| 99 | + |
| 100 | +"Unused" Data Manager columns are columns that contain data that is not being used in the labeling configuration. |
| 101 | + |
| 102 | +For example, you may include meta or system data that you want to view as part of a project, but you don't necessarily want to expose that data to Annotators and Reviewers. |
| 103 | + |
| 104 | +<img style="max-width: 600px" src="/images/releases/2-29-dm-columns.png" alt="Screenshot"/> |
| 105 | + |
| 106 | +#### Manager and Reviewer access to the Annotator Dashboard |
| 107 | + |
| 108 | +Managers and Reviewers will now see a link to the Annotator Dashboard from the Home page. |
| 109 | + |
| 110 | +The [**Annotator Dashboard**](dashboard_annotator) displays information about their annotation history. |
| 111 | + |
| 112 | +**Managers:** |
| 113 | + |
| 114 | + |
| 115 | + |
| 116 | +**Reviewers:** |
| 117 | + |
| 118 | + |
| 119 | + |
| 120 | +#### Show models in the Members dashboard |
| 121 | + |
| 122 | +If your project is using predictions, you will now see a **Show Models** toggle on the [Members dashboard](https://docs.humansignal.com/guide/dashboard_members). |
| 123 | + |
| 124 | +This will allow you to view model agreement as compared to annotators, other models, and ground truths. |
| 125 | + |
| 126 | + |
| 127 | + |
| 128 | + |
| 129 | +#### Set model provider API keys for an organization |
| 130 | + |
| 131 | +There is a new **Model Providers** page available at the organization level where you can configure API keys to use with LLM tasks. |
| 132 | + |
| 133 | +If you have previously set up model providers as part of your Prompts workflow, they are automatically included in the list. |
| 134 | + |
| 135 | +For more information, see [Model provider API keys for organizations](https://docs.humansignal.com/guide/model_providers). |
| 136 | + |
| 137 | + |
| 138 | + |
| 139 | + |
| 140 | +#### Improved UX on the Organization page |
| 141 | + |
| 142 | +The Organization page (only accessible to Owner and Admin roles) has been redesigned to be more consistent with the rest of the app. |
| 143 | + |
| 144 | +Note that as part of this change, the [**Access Token**](https://docs.humansignal.com/guide/access_tokens) page has been moved under **Settings**. |
| 145 | + |
| 146 | +**Before:** |
| 147 | + |
| 148 | + |
| 149 | + |
| 150 | +**After:** |
| 151 | + |
| 152 | + |
| 153 | + |
| 154 | +#### New email notification option for users who are not activated |
| 155 | + |
| 156 | +Administrators and Owners can now opt in to get an email notification when a new user logs in who has not yet been assigned a role. |
| 157 | + |
| 158 | +Like all email preferences, this can be disabled and hidden for the whole organization on the **Organization > Usage and License** page. |
| 159 | + |
| 160 | + |
| 161 | + |
| 162 | + |
| 163 | +#### Apply labels from multiple `<Labels>` controls |
| 164 | + |
| 165 | +When you have a labeling configuration that includes multiple `<Labels>` blocks, like the following: |
| 166 | + |
| 167 | +```xml |
| 168 | +<View> |
| 169 | +<Text name="text" value="$text" granularity="word"/> |
| 170 | +<Labels name="category" toName="text" choice="single"> |
| 171 | + <Label value="Animal" background="red"/> |
| 172 | + <Label value="Plant" background="darkorange"/> |
| 173 | +</Labels> |
| 174 | +<Labels name="type" toName="text" choice="single"> |
| 175 | + <Label value="Mammal" background="green"/> |
| 176 | + <Label value="Reptile" background="gray"/> |
| 177 | + <Label value="Bird" background="blue"/> |
| 178 | +</Labels> |
| 179 | +</View> |
| 180 | +``` |
| 181 | + |
| 182 | +You can now choose multiple labels to apply to the selected region. |
| 183 | + |
| 184 | +<video style="max-width: 800px;" class="gif-border" autoplay loop muted> |
| 185 | + <source src="/images/releases/2-29-multilabels.mp4"> |
| 186 | +</video> |
| 187 | + |
| 188 | +#### Multiple SDK enhancements |
