# Release 0.0.3 (/docs/release-notes/0.0.3)



Project `start` and `end` stay **published date**, like every other proof-point type. Activity-window overlap is opt-in via `activeDuring`. Activity-window capital charts move to a new endpoint.

This is an **additive** change on the project routes introduced in [Release 0.0.1](/docs/release-notes/0.0.1). Deprecated `/indicators/grants/time-series` forwards its chart window onto the new activity time-series endpoint.

| Route                                              | What changed                                                                                                                                |
| -------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- |
| `POST /proof-points/projects/search`               | Optional `activeDuring` for `[startField, endField]` overlap. `start` / `end` still filter `publishedAt`.                                   |
| `POST /proof-points/projects/time-series`          | Published-at histogram again. Optional `activeDuring` only narrows which projects are counted.                                              |
| `POST /proof-points/projects/activity-time-series` | **New.** Calendar buckets over `activeDuring.start` / `activeDuring.end`. `amountFields` are numeric fallbacks (first positive value wins). |
| `POST /proof-points/projects/correlation-matrix`   | Optional `activeDuring` plus project-specific filters (`statuses`, `programs`, …).                                                          |
| `POST /proof-points/projects/top-terms`            | Same as correlation.                                                                                                                        |
| Other `/proof-points/*`                            | Unchanged                                                                                                                                   |

A missing document `endField` is treated as **ongoing**. On the activity time-series route, `counts` are projects whose interval overlaps each bucket. `amount` is prorated by how much of that interval sits in the bucket. If `amountFields` is omitted or empty, each project counts as `1`.

`activeDuring.start` and `activeDuring.end` are required on activity time-series. Search, correlation, top-terms, and regular time-series treat omitted body `start` as open and default `end` to now.

Schemas for these operations are in the [OpenAPI spec](https://connect-api.trendtracker.ai/openapi.json) and the [API reference](/docs/api-reference). See [Projects](/docs/proof-points/projects) for request examples.
