+
+New minor v2.5 BabbleSim release
+A minor release of BabbleSim has just been done (v2.5) and it is being propagated to Zephyr and the NCS manifest.

+
+### 2024/09/02 : New Babblesim release (v2.3)
+
+There has been a minor release update to Babblesim (v2.3) which includes new APIs in the libCrypto library which are used by the nRF54L HW models.
+This release is, as always, backwards compatible with previous releases so you can safely update to it.
+
+Zephyr's manifest points now to this release, and eventually this change will be downmerged to NCS.
+
+If you are getting bsim from Zephyr's manifest, in your Zephyr workspace, in Zephyr's latest main, do:
+
+```
+west update
+cd ${BSIM_OUT_PATH}
+make everything
+```
+
+If you are getting bsim using the repo manifest, tracking the main manifest master branch, you can just do:
+
+```
+cd ${BSIM_OUT_PATH}
+repo sync
+make everything
+```
+
+If you do not update the bsim installation, but use updated HW models, the HW models (in zephyr.exe) will give you a runtime warning as they fall back to the old libCrypto API.
+If you do not use the nRF54L CCM model, this is harmless.
+
+If you use it, you will encounter CCM encryption errors depending on module configuration (specially for 802.15.4).
+

+
+### 2024/03/13 : Coded Phy support added to BabbleSim and nRF HW models
+
+Coded Phy is now supported in BabbleSim, the [nRF HW models](https://github.com/babbleSim/ext_NRF_hw_models),
+and will soon be also in [Zephyr's simulated targets](https://github.com/zephyrproject-rtos/zephyr/pull/70158)
+Note that using this functionality requires updating the simulator itself to the latest version.
+
+Notes:
+
+* For the Phy:
+    * Changes in the Phy will result in random draw changes. That is, you may see bit or synchronization errors change between this version of the Phy and a previous version with all being equal.
+    * There has been a correction in the bit error calculation. The BER is now capped to 50%
+* If you have your own modem performance models, note there has been an API change in the Phy-modem IF, as now the model digital performance gets also the coding rate as parameter.
+* v2 channel activity dumps are now enabled (v1 dumps are still produced). v2 have more information than v1 dumps.
+
+-------------
+
+### 2023/09/29 : nRF5340 models added
+
+The [nRF HW models](https://github.com/babbleSim/ext_NRF_hw_models) now include models of the nRF5340, and a
+[target board has been added in Zephyr](https://docs.zephyrproject.org/latest/boards/native/nrf_bsim/doc/nrf5340bsim.html)
+which can be used to target either the cpuapp or cpunet cores, or build images using both.
