## 0.111.0
6+
7+
### 💡 Enhancements 💡
8+
9+
- `auto-instrumentation`: set OTEL_LOGS_EXPORTER env var to otlp in python instrumentation (#3330)
10+
11+
- `collector`: Expose the Collector telemetry endpoint by default. (#3361)
12+
13+
The collector v0.111.0 changes the default binding of the telemetry metrics endpoint from `0.0.0.0` to `localhost`.
14+
To avoid any disruption we fallback to `0.0.0.0:{PORT}` as default address.
15+
Details can be found here: [opentelemetry-collector#11251](https://github.com/open-telemetry/opentelemetry-collector/pull/11251)
16+
17+
18+
- `auto-instrumentation`: Add support for specifying exporter TLS certificates in auto-instrumentation. (#3338)
19+
20+
Now Instrumentation CR supports specifying TLS certificates for exporter:
21+
```yaml
22+
spec:
23+
exporter:
24+
endpoint: https://otel-collector:4317
25+
tls:
26+
secretName: otel-tls-certs
27+
configMapName: otel-ca-bundle
28+
# otel-ca-bundle
29+
ca_file: ca.crt
30+
# present in otel-tls-certs
31+
cert_file: tls.crt
32+
# present in otel-tls-certs
33+
key_file: tls.key
34+
```
35+
36+
* Propagating secrets across namespaces can be done with https://github.com/EmberStack/kubernetes-reflector or https://github.com/zakkg3/ClusterSecret
37+
* Restarting workloads on certificate renewal can be done with https://github.com/stakater/Reloader or https://github.com/wave-k8s/wave
38+
39+
- `collector`: Add native sidecar injection behind a feature gate which is disabled by default. (#2376)
40+
41+
Native sidecars are supported since Kubernetes version `1.28` and are availabe by default since `1.29`.
42+
To use native sidecars on Kubernetes v1.28 make sure the "SidecarContainers" feature gate on kubernetes is enabled.
43+
If native sidecars are available, the operator can be advised to use them by adding
44+
the `--feature-gates=operator.sidecarcontainers.native` to the Operator args.
45+
In the future this may will become availabe as deployment mode on the Collector CR. See [#3356](https://github.com/open-telemetry/opentelemetry-operator/issues/3356)
46+
47+
- `target allocator, collector`: Enable mTLS between the TA and collector for passing secrets in the scrape_config securely (#1669)
48+
49+
This change enables mTLS between the collector and the target allocator (requires cert-manager).
50+
This is necessary for passing secrets securely from the TA to the collector for scraping endpoints that have authentication. Use the `operator.targetallocator.mtls` to enable this feature. See the target allocator [documentation](https://github.com/open-telemetry/opentelemetry-operator/tree/main/cmd/otel-allocator#service--pod-monitor-endpoint-credentials) for more details.
51+
52+
### 🧰 Bug fixes 🧰
53+
54+
- `collector-webhook`: Fixed validation of `stabilizationWindowSeconds` in autoscaler behaviour (#3345)
55+
56+
The validation of `stabilizationWindowSeconds` in the `autoscaler.behaviour.scale[Up|Down]` incorrectly rejected 0 as an invalid value.
57+
This has been fixed to ensure that the value is validated correctly (should be >=0 and <=3600) and the error messsage has been updated to reflect this.
58+
59+
