The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/). ## 0.4.3 - 2025-10-10 ### Fixed * Fix performance issue introduced by the improved line parsing from release 0.4.2. (Pull #40) ## 0.4.2 - 2025-10-07 ### Fixed * Fix incorrect newline parsing that was not compliant with SSE spec. (Pull #37) ## 0.4.1 - 2025-06-24 ### Fixed * Always close the response async generator in `aiter_sse()`. (Pull #30) ## 0.4.0 - 2023-12-22 ### Removed * Dropped Python 3.7 support, as it has reached EOL. (Pull #21) ### Added * Add official support for Python 3.12. (Pull #21) ### Fixed * Allow `Content-Type` that contain but are not strictly `text/event-stream`. (Pull #22 by @dbuades) * Improve error message when `Content-Type` is missing. (Pull #20 by @jamesbraza) ## 0.3.1 - 2023-06-01 ### Added * Add `__repr__()` for `ServerSentEvent` model, which may help with debugging and other tasks. (Pull #16) ## 0.3.0 - 2023-04-27 ### Changed * Raising an `SSEError` if the response content type is not `text/event-stream` is now performed as part of `iter_sse()` / `aiter_sse()`, instead of `connect_sse()` / `aconnect_sse()`. This allows inspecting the response before iterating on server-sent events, such as checking for error responses. (Pull #12) ## 0.2.0 - 2023-03-27 ### Changed * `connect_sse()` and `aconnect_sse()` now require a `method` argument: `connect_sse(client, "GET", "https://example.org")`. This provides support for SSE requests with HTTP verbs other than `GET`. (Pull #7) ## 0.1.0 - 2023-02-05 _Initial release_ ### Added * Add `connect_sse`, `aconnect_sse()`, `ServerSentEvent` and `SSEError`.
