+Bosch Sensortec Environmental Cluster (BSEC) Software v1.4.8.0 released on July 8th, 2020
 
 The BSEC fusion library has been conceptualized to provide a higher-level signal processing and fusion for the BME680. The library receives compensated sensor values from the sensor API. It processes the BME680 signals to provide the requested sensor outputs.

-### 4. Additional core specific modifications
-
-#### ESP8266 - modify the linker script header
-
-Due to the architecture of the ESP8266's memories and current size of the BSEC library, upon compilation, you will receive an error: ```section `.text1' will not fit in region `iram1_0_seg'```. In order to solve this, you will need to modify the linker script and specifically define where the library should be placed in memory.
-
-You will need to modify the file `eagle.app.v6.common.ld.h` typically found in `{YourESP8266PPackageDirectory}\tools\sdk\ld`. 
-
-With reference to the linker script [here](https://github.com/esp8266/Arduino/blob/master/tools/sdk/ld/eagle.app.v6.common.ld.h),
-
-After line [`177 *libwps.a:(.literal.* .text.*)`](https://github.com/esp8266/Arduino/blob/68ee1216454eeea49dd3452c6ff21bc748f397b6/tools/sdk/ld/eagle.app.v6.common.ld.h#L177),
-add `*libalgobsec.a:(.literal.* .text.*)`, which should look like,
