A session spans `[start_time, end_time]` and belongs to a selected time window whenever the two intervals overlap. Previously sessions were filtered by `start_time` alone, so a long-running session that began before the window — but had activity inside it — was excluded. Those sessions now appear. * **Wider, more accurate results** — session lists, counts, and metrics for a time range now include every session active during the window, not only those that started inside it * **Database migration** — upgrading to 18.0.0 runs a schema migration that adds a composite index supporting the new filter. On large PostgreSQL deployments, set `PHOENIX_MIGRATE_INDEX_CONCURRENTLY=true` to build indexes without locking writes. See [MIGRATION.md](https://github.com/Arize-ai/phoenix/blob/main/MIGRATION.md) for operator guidance. # Batch Annotation Config Management July 14, 2026 **Available in arize-phoenix 17.30.0+** The annotation settings page now supports selecting multiple annotation configurations at once. Select a range of configs and delete them in a single action, with a confirmation dialog that reports how many will be removed. # Customizable Data Tables July 12, 2026 **Available in arize-phoenix 17.27.0+** Tables across Phoenix now adapt to how you work. A redesigned column selector lets you pick which columns appear and drag to reorder them, and your layout persists per project. * **Drag-and-drop reordering** — reorder columns on the traces, sessions, and experiments tables from the redesigned column selector * **Customizable prompts table** — choose which columns the prompts table shows * **Authorship columns** — datasets and prompts surface who last updated them * **Span I/O previews** — hover a truncated input or output cell to preview the full value in a tooltip # Dataset Metrics Tab July 11, 2026 **Available in arize-phoenix 17.25.0+** The dataset page gains a **Metrics** tab that charts experiment results over time, so you can track how successive experiments on a dataset trend without opening each one individually. # Credential Discovery from a `.env.phoenix` File July 11, 2026 **Available in arize-phoenix-client 2.13.0+ (Python) and @arizeai/phoenix-config 0.3.0+ (TypeScript)** Phoenix SDKs can now discover configuration from a `.env.phoenix` file. When a setting is not provided by argument or environment variable, the client walks up from the current working directory to the nearest `.env.phoenix` file and reads `PHOENIX_`-prefixed keys from it (dotenv format). ```bash theme={null} # .env.phoenix PHOENIX_COLLECTOR_ENDPOINT=http://localhost:6006 PHOENIX_API_KEY=your-api-key ``` Explicit arguments and environment variables always take precedence — the file never overrides anything already set. Set `PHOENIX_DISCOVER_CONFIG=false` to disable discovery entirely. ```python theme={null} from phoenix.client import Client # Endpoint and key are read from .env.phoenix if not otherwise set client = Client() ``` The same discovery powers the TypeScript client, CLI, MCP server, and OpenTelemetry setup through `@arizeai/phoenix-config`. # Unified `PHOENIX_PROJECT` Environment Variable July 11, 2026 **Available in arize-phoenix-client 2.13.0+ (Python) and @arizeai/phoenix-config 0.2.0+ (TypeScript)** Project name resolution is now consistent across every SDK surface. Both `PHOENIX_PROJECT` (canonical) and `PHOENIX_PROJECT_NAME` (supported alias) route to the same project, with explicit arguments still taking precedence over both. If the two variables are set to conflicting values, `PHOENIX_PROJECT` wins and a one-time warning naming both values is emitted. # Filter Projects by Name in the Python Client July 11, 2026 **Available in arize-phoenix-client 2.13.0+ (Python)** `projects.list()` accepts a `name_contains` argument for a case-insensitive substring match, so you can locate projects without paging through the full list. ```python theme={null} from phoenix.client import Client client = Client() projects = client.projects.list(name_contains="agent") ``` # GPT 5.6 Family in the Playground July 9, 2026 **Available in arize-phoenix 17.23.0+** The OpenAI GPT 5.6 family (`gpt-5.6-sol`, `gpt-5.6-terra`, and `gpt-5.6-luna`) is now selectable in the Playground and prompts for the OpenAI provider. # Global Search Command Palette (⌘K) July 8, 2026 **Available in arize-phoenix 17.21.0+** Jump to anything in Phoenix without navigating the sidebar. Press `⌘K` (or click the search affordance in the side navigation) to open a command palette that searches projects, datasets, experiments, and prompts by name or description, alongside top-level pages and the resources you viewed most recently. * **Search everything** — projects, datasets, experiments, and prompts in one place * **Recently viewed** — recent resources surface instantly for quick return trips * **Keyboard-first** — open with `⌘K` and navigate results without the mouse # Session Workflow Enhancements July 8–13, 2026 **Available in arize-phoenix 17.21.0+ through 17.28.0+** Working with sessions gets a set of upgrades across the sessions table and detail view: * **Session stats panel** — a collapsible aside on the sessions table shows the session count, average traces per session, session duration (average, P50, and P99), and per-label annotation summaries (arize-phoenix 17.21.0+) * **Total session count** — project cards display the total number of sessions (arize-phoenix 17.21.0+) * **Turn dividers** — session detail view separates turns with dividers and a copy control (arize-phoenix 17.21.0+) * **Session annotation editing** — add and edit session-level annotations directly in the session detail view (arize-phoenix 17.28.0+) * **Automatic cleanup** — orphaned sessions (those left without any traces) are swept after a one-hour grace period, keeping session lists clean (arize-phoenix 17.21.0+) # Playground Refinements July 11–14, 2026 **Available in arize-phoenix 17.26.0+ through 17.30.0+** * **Output error count** — the Playground surfaces how many outputs errored in a run (arize-phoenix 17.30.0+) * **Collapsible sections** — collapse Playground panels to focus on the parts you're editing (arize-phoenix 17.28.0+) * **Clearer forced tool choice** — the tool-choice menu spells out what forcing a specific tool does (arize-phoenix 17.26.0+) Group related traces into sessions and inspect them together. Manage projects, datasets, experiments, and annotations from Python.
