Version 1.4
===========

New minor release, created on 24th April 2019. Milestone: :github-fw-milestone:`Release 1.4 <4>`

Tested mainly with Vivado 2017.4 and 2018.3. Contains Ethernet-based example designs for:

* Enclustra AX3 module, using the RGMII PHY on the PM3 baseboard
* Xilinx KC705 eval board
* Xilinx KCU105 eval board
* Xilinx ZCU102 eval board
* PC053a

The main new feature in this release is a **PCIe transport interface for the IPbus transactor**; this allows users to send and receive lists of IPbus transactions to/from the transactor via a PCIe link. The repository includes PCIe-based example designs for:

* HiTech Global K800
* Xilinx VCU118 eval board


Core
----

The source code for the Ethernet-transactor interface has been moved out of ``components/ipbus_core``.

* ``ipbus_ctrl.vhd`` can now be found in ``components/ipbus_util/firmware/hdl/masters``
* The source code that implements the Ethernet-transactor interface has been moved to ``components/ipbus_transport_udp/firmware/hdl``; the corresponding top-level 'depfile' is ``components/ipbus_transport_udp/firmware/cfg/ipbus_transport_udp.dep``


Boards, example designs and utilities
-------------------------------------

We have removed redundant board-specific simulation files and simplified the directory structure under ``boards`` [:github-fw-issue:`89`] - specifically, the directory structure changed as follows:

* ``boards/enclustra_ax3_pm3/base_fw`` becomes ``boards/enclustra_ax3_pm3``
* ``boards/glib_v3/base_fw`` becomes ``boards/glib_v3``
* ``boards/kc705/base_fw/kc705_basex`` becomes ``boards/kc705/basex``
* ``boards/kc705/base_fw/common`` becomes ``boards/kc705/common``
* ``boards/kc705/base_fw/kc705_gmii`` becomes ``boards/kc705/gmii``

* ``boards/kcu105/base_fw/kcu105_basex`` becomes ``boards/kcu105/basex``

* ``boards/pc053a/base_fw`` becomes ``boards/pc053a``
* ``boards/zcu102/base_fw/zcu102_basex`` becomes ``boards/zcu102/basex``

**Bugfixes**

* ZCU102: Added missing top-level SFP enable signal, and corrected comments for pin constraints [:github-fw-issue:`103`]
