## [1.26.0] - 2025-06-26
10+
11+
This is a feature release, primarily addressing future compatibility changes for
12+
the next nRF-Connect SDK release.
13+
14+
### 📈 Added
15+
16+
- Zephyr:
17+
18+
- Add support for the ESP32 chip on Zephyr, adding to the existing support for
19+
ESP32-S3 and ESP32 C series chips.
20+
21+
- Add support for building the Memfault SDK on the `native_sim` board. Note
22+
that Memfault does not support reboot tracking or coredumps on this target,
23+
but other features are supported.
24+
25+
### 🛠️ Changed
26+
27+
- General:
28+
29+
- Add a `MEMFAULT_ENABLE_WARNING(warning)` macro complementing the existing
30+
`MEMFAULT_DISABLE_WARNING(warning)` macro. This macro is only implemented
31+
for GCC + Clang.
32+
33+
- Zephyr:
34+
35+
- Remove the External Module logic, used to support multiple Zephyr versions,
36+
and instead use the normal Zephyr module Kconfig path specifier. There
37+
should be no user-facing changes from this change. It addresses an issue
38+
with Kconfig symbol linting.
39+
40+
- In the [Zephyr QEMU sample app](examples/zephyr/qemu/qemu-app/prj.conf), add
41+
the `--param=min-pagesize=0x1000` compiler option, which will catch
42+
dereferences to low memory addresses. This is only for static analysis
43+
purposes and does not affect any behavior.
44+
45+
- ESP-IDF:
46+
47+
- The heartbeat metrics timer is now enabled by default when
48+
`CONFIG_MEMFAULT_DEEP_SLEEP_SUPPORT=y`. Version `1.25.0`, which added deep
49+
sleep support, had disabled the normal heartbeat metrics timer by default.
50+
The default behavior can be overridden with the Kconfig option
51+
`CONFIG_MEMFAULT_METRICS_HEARTBEAT_TIMER_ENABLE`.
52+
53+
- nRF-Connect SDK:
54+
55+
- Replace use of `LTE_LC_ON_CFUN` with `NRF_MODEM_LIB_ON_CFUN` for nRF-Connect
56+
SDK v2.8.0+. This deprecated API is scheduled to be removed in the next
57+
nRF-Connect SDK release.
