##### Fixes and improvements

General

* playback: fix panic when MP4 muxer flushes with no samples (https://github.com/bluenviron/mediamtx/issues/5867)
* redact sensitive headers in HTTP debug logs (https://github.com/bluenviron/mediamtx/issues/5873)
* fix(recordstore): decode timezone offset minutes correctly (https://github.com/bluenviron/mediamtx/issues/5884)
* improve HTTP server performance (https://github.com/bluenviron/mediamtx/issues/5886) log incoming requests without cloning.
* prevent truncation of 64-bit values on 32-bit platforms (https://github.com/bluenviron/mediamtx/issues/5902)

RTSP

* add rtspScale parameter to inject Scale header on PLAY (https://github.com/bluenviron/mediamtx/issues/5800)
* client: switch automatically to TCP in case of H264 packetization-mode=0 (https://github.com/bluenviron/gortsplib/issues/1086)
* support VP8 streams with multiple partitions (https://github.com/bluenviron/mediamtx/issues/5426) (https://github.com/bluenviron/gortsplib/issues/1090)
* allow FU-A and STAP-A packets with H264 packetization-mode 0 (https://github.com/bluenviron/mediamtx/issues/5887) (https://github.com/bluenviron/gortsplib/issues/1092)

WebRTC

* skip unresolvable webrtcAdditionalHosts entries instead of aborting (https://github.com/bluenviron/mediamtx/issues/5845)

RPI Camera

* support encoding primary stream with MJPEG (2/2) (https://github.com/bluenviron/mediamtx/issues/5892)
* support encoding secondary stream with H264 (2/2) (https://github.com/bluenviron/mediamtx/issues/4485) (https://github.com/bluenviron/mediamtx/issues/5898)
* add unified rpiCameraH264Profile, rpiCameraH264Level params (https://github.com/bluenviron/mediamtx/issues/5894) These replace rpiCameraHardwareH264Profile, rpiCameraHardwareH264Level, rpiCameraSoftwareH264Profile, rpiCameraSoftwareH264Level.
* fix race condition that prevents decoding the stream (https://github.com/bluenviron/mediamtx-rpicamera/issues/109) (https://github.com/bluenviron/mediamtx/issues/5861) When a player immediately connects to a newly-created stream, SPS/PPS might not be available, neither in the SDP and neither in-band. Prevent the issue by always sending SPS/PPS in-band.
* improve performance by computing frame size once (https://github.com/bluenviron/mediamtx-rpicamera/issues/111)
* fix wrong timestamp being passed to openh264 (https://github.com/bluenviron/mediamtx-rpicamera/issues/114)

##### Security

Binaries are compiled from source code by the [Release workflow](https://github.com/bluenviron/mediamtx/actions/workflows/release.yml), which is a fully-visible process that prevents any change or external interference in produced artifacts.

Checksums of binaries are also published in a public blockchain by using [GitHub Attestations](https://docs.github.com/en/actions/concepts/security/artifact-attestations), and they can be verified by running:

```
ls mediamtx_* | xargs -L1 gh attestation verify --repo bluenviron/mediamtx
```

You can verify checksums of binaries by downloading `checksums.sha256` and running:

```
cat checksums.sha256 | grep "$(ls mediamtx_*)" | sha256sum --check
```
