Version History

---------------

For a full view of changes please see the [changelog](https://github.com/sparkfun/OpenLog/blob/master/CHANGELOG.md). 

OpenLog v4 is refactored with better RAM utilization for better performance at higher record speeds (115200/57600).

OpenLog v3 is stable, supports FAT32 cards up to 64GB and supports higher record speeds (115200/57600).

OpenLog v2 is a bit buggy but supports FAT32 and SD cards up to 16GB.  

OpenLog v1 is stable but only supports FAT16 and up to 2GB.  

* **v1.0**  Buggy initial release

* **v1.1**  Small changes to system settings and EEPROM storage.

* **v1.2**  Added wild card to listing and remove commands. Added read file command.

* **v1.3**  Added auto buffer record if unit sits idle for more than 5 seconds.

* **v1.4**  Increase buffer size to 900 bytes. Pinning down URU errors.

* **v1.5**  Lowered power consumption to ~2mA avg. Added 4800 and 19200 baud rates.

* **v1.51** Added configurable escape character, and escape character amount.

* **v1.6**  Added ability to configure via config.txt file.

* **v2.0**  Massive overhaul. Ported to sdfatlib. Now supports FAT16/FAT32/SD/SDHC.

* **v2.1**  Power save not working. Fixed issue 35. Dropping characters at 57600bps.

* **v2.11** Tested with 16GB microSD. Fixed issues 30 & 34. Re-enable power save.

* **v2.2**  Modified append_file() to use a single buffer. Increased HardwareSerial.cpp buffer to 512 bytes.

* **v2.21** ringp fork brought in. rm dir, cd .., and wildcards now work!

* **v2.3**  Migrated to v10.10.10 of sdfatlib. Moved to inline RX interrupt and buffer.

* **v2.4**  Merged ringp updates. Commands cd, rm, ls work again!

* **v2.41** Power loss bug fixed. Adding support for 38400bps for testing with SparkFum 9DOF IMU logging. 

* **v2.5**  Added software reset command. Modified the read command to print extended ASCII characters.

* **v2.51** Changed command prompt control to ignore \n for easier control from microcontroller.

* **v3.0**  Migration to Arduino v1.0 and better recording speed at 115200bps and 57600bps.

* **v3.1**  Better handling of recording during power loss.

* **v3.2**  Freed up RAM for larger RX ring buffer. Added support for wildcards and ability to ignore emergency override.

* **v3.3**  Added ability to ignore escape character checking and corrected incremental log naming.

* **v4.0**  Re-worked to be compatible with Arduino v1.6.x. Freed RAM to increase RX buffer size.
