# Change Log
## [4.0.1] - 2019-09-13
### Software
#### Fixed
- File Descriptor closed correctly so that the same process can do
``trtl_open()`` and ``trtl_close()`` multiple times
## [4.0.0] - 2019-05-14
### Documentation
#### Changed
- moved to sphinx and ReST
- merged HDL and software
- improved with examples
- doxygen and wbgen2 integration
#### Added
- Tools section
- Demo section
- Glossary section
### Gateware
#### Changed
- soft-CPU is now uRV
- each core has a set of dedicated HMQ and RMQ
#### Added
- uRV debug interface
- notification interrupts from firmwares
- new test benches
### Software
#### Changed
- synchronous messages redesigned
- HMQ API reflects gateware changes
- firmware library and framework improvements
- re-design Python wrapper a bit
#### Added
- driver auto-configuration from configuration ROM
- GDB agent to debug firmware
- tool to generated empty projects
- tools to interact with firmware framework
#### Removed
- Driver message filter
- LM32 support
- function to pause and start CPU execution
### Demo
#### Added
- new demo section
### Tests
#### Added
- new integration test section
## [3.1.0] - 2018-03-09
### Gateware
This release brings in the gateware from wr-node-core repository, such as it
is being used in the released and deployed v1.0 version of masterFIP.
The relevant commit is 96a7859 from git://ohwr.org/white-rabbit/wr-node-core.git.
This is a "known to work" version of the gateware, still using the "node core" name.
Following releases will switch to the "mock turtle" name.
## [3.0.0] - 2017-09-14
### Software
The realease of a new version has been necessary because I decided to remove
the debug interface from the API. This interface has been problematic, and
its original purpose has been neglected
#### Added
- standard TTY interface to access the soft-CPU serial console output
#### Removed
- debugfs interface to access the soft-CPU serial console output
- removed library functions to access the debugfs console output
- the ``mockturtle-messages`` tool is not able anymore to access the soft-CPU
serial console output
#### Fixed
- minor fixes
## [2.0] - 2016-06-08
### Software
#### Changed
- Project change name to Mock Turtle. this means renaming all files
functions, data structures, enumerates and variables to a new
convention
- port output real-time application to the real-time library
- improve kernel driver performance
#### Added
- unittest
## [1.1] - 2015-10-20
### Software
#### Changed
- minor changes in API behaviour on error
## [1.0] - 2015-09-17
### Software
- first release White Rabbit Node Core
