# Digi International iDigi Dia Release Notes

Release Notes for Version 40002675_G (1.4.14):

> Core System Changes

> > - A new core service, the Tracing Manager, has been introduced. Use the the tracer test device

> >       src\devices\tracer_test_device.py

> >   to test tracing configurations.

> > - A new method ‘request_shutdown’, has been added to the core. This allows components in the system to request that Dia shut down and exit. This functionality is also exposed on the console, RCI, and XMLRPC interfaces.

> > - New and restructured access to sample code through the Digi ESP, this has resulted in some code such as the ‘persistent_settings’ device being relocated so it is clear the purpose it serves in the system as for informative reference and to allow sample project creation in the ESP as well.

Release Notes for Version 40002675_F (1.4.6):

> Core System Changes

> > - An example driver which saves device settings dynamically has been added to the code – see file:

> >       src\devices\persistant_settings.py.

> >   The example shows an alarm limit which can be updated remotely via iDigi.

> > - Channel names can no longer use an embedded ‘.’ (period)– several Dia presentations were confused by this. Developers who made use of dots within their drivers will need to change their design.

> > - The Python traceback displayed when common DDO requests time out has been removed.

> Device Changes

> > - XBee Device Manager has had ‘update_skiplist’ default changed from True, to False, which means by default the Dia will attempt to reconfigure all devices every time it restarts. (v37747)
> > - XBee DIO adapter driver supports a timed update (for example once per 30 seconds) as well as report-on-change. The output channel samples are also refreshed every time new data arrives regardless of change. (v33749,v33795)

> Presentation Changes

> > - SMS support has been added. To enable SMS data to be upload in your iDigi cloud storage, you must speak to your iDigi sales representative, requesting to have SMS support added to your iDigi account subscription. It is not free since a third party service is involved. Sending SMS messages to your own phone or services is free and not related to this iDigi subscription.
> > - The idigi_db driver will upload correctly even if your realtime clock is changed - for example due to a time-zone change (v32415)
> > - idigi_db has had the logic of settings interval and sample-threshold fine-tuned. Setting either to zero allows the other to completely control the upload process. (v32386)

> Known Issues

> > - Dia logger: at least one instance of the logger is supported. Various products running Dia have different limitations on the number of open files supported, which means you can probably run 2 or even 5 file loggers, but you probably cannot run 20.
> > - Dia developers: In some configurations trace output may be excessively verbose. For now, developers should comment out undesired lines to limit to messages of interest. The next release of Dia will include a formal “tracing” facility which allows trace lines to be enabled or disabled on a module or instance basis.
> > - Embedded Web Presentation: issue with older AJAX files means IE 8 users may need to use IE8’s page refresh to see expected information. This will be fixed in a future release.
> > - Time Zone Usage: most modules within Dia use UTC/Greenwich time. The design intent is that all undocumented uses of time will be UTC, and any module desiring local time should have a user-setting to select either UTC or local time, plus indicate in the output which time-zone is being used. Not all of the demo code has been updated to follow this design guideline.

Release Notes for Version 40002675_E (1.3.13):

> Core System Changes

> > - The Dia documentation has been extended with additional documentation aimed to aid in extending Dia with custom modules. The documentation now includes more in-depth development guides and an integrated API reference.

> Device Changes

> > - Added tank devices to support the Digi Tank Solutions Kit.

Release Notes for Version 40002675_D (1.3.8):

> Core System Changes

> > - Using/developing Dia on a MacOS system should now be easier. Rewrote some incorrect path and system operations to be more platform neutral.
> > - You may now choose not to byte-compile dia.zip using the ‘-c False’ option of ‘make.py’.
> > - Portions of the system that rely on doc-strings have been rewritten so that the Python interpreter ‘-OO’ flag may be used to remove doc-strings and functionality will not be lost.

> Device Changes

> > - A new Local IO (Analog and Digital) driver has been added that simplifies configuration of devices such as the ConnectPort X3 that have local analog and digital I/O.
> > - The XBee configuration process has been streamlined to allow device configuration to complete more quickly in the majority of environments.
> > - The XBee Device Manager will now by default save new versions of the settings file while processing and configuring nodes discovered on the mesh network. This behavior is configurable with the ‘update_skiplist’ configuration item on the XBee Device Manager.
> > - The Alarm Clock Device no longer triggers channel updates only on specific time values for its intervals. The updates are now relative to the start time of the driver. This simplifies the code and makes it much more robust.

> Presentation changes

> > - The Console presentation may now be set to provide a CLI on serial ports of the device.

> Deprecation Warning

> > - With the addition of the Local IO (Analog and Digital) driver, the Local Analog and Local Digital devices are obsolete and will be removed in an upcoming release of Dia

> > - XBeeConfigBlockConfigCB has been removed. Exposing a configuration process during the configuration steps for XBee radios reduced the optimizations and assumptions that could be made to streamline this process.

> >   As a result, the Massa M3 driver has been updated.

> > - The XBee Display driver has been removed. This product is not generally available.

Release Notes for Version 40002675_C1 (1.2.20):

> Bug Fixes

> > - An issue existed in 1.2.19 where XBee devices configured for extended sleep intervals were not getting their SN parameter set.

Release Notes for Version 40002675_C (1.2.18):

> Deprecation Warning

> > - This release currently supports module firmware older than the 2.8.3 version. To support future platforms consistently a future release of Dia will require 2.8.3 at a minimum

> Known Limitations:

> > - The XBee Device Manager and associated XBee device drivers only support the ZB (ZigBee) modules. 802.15.4, DigiMesh, and other module variants are unsupported at this time.

> > - Recent versions of Digi ConnectPort firmware provide a firmware update feature. Having this feature on interacts poorly with Dia operation. We strongly recommend disabling automatic operation.

> >   To disable this feature, in the Configuration -> XBee Network menu, under the Firmware Update Setup section, unclick the Enable over the air firmware updates checkbox and apply the settings.

> >   Alternatively, through the CLI, telnet to the gateway device and run the following command:

> >       set xbee fw_update=off

> >   If you desire to use this functionality to update firmware on your mesh nodes, please do this during a time where Dia is not active, and disable the feature again when complete.

> Core System Changes:

> > - Added support for Python 2.6 for future Digi device software releases.
> > - New centralized scheduler service available in from CoreServiceManager. Implemented to avoid the creation of threads (with their associated memory cost). Scheduler is requested via core.get_service(“scheduler”). See implementation in src/core/scheduler.py
> > - Added “Python Representation” (.pyr) settings serialization system. Make .pyr the default output of the make.py process. Pre-parsing the YML file to Python saves 600k of YAML parser overhead on system startup.
> > - Logging sub-system re-expressed to be record number indexed rather than time indexed. Time was found to be too variable–when using automatic clock adjustments–to be useful when trying to find sets of log events. Most interface changes are captured in: `src/channels/channel_database_interface.py`
> > - Rewrote the Simple Logger – a device capable of receiving and printing trace messages of log events–to conform to new elements of the logging sub-system. See: src/channels/logging/simple_logger
> > - Re-implemented the file based logger. Log file is fully journaled, it can be iterated backwards and forwards and supports searching for individual records. Increased log file density: it should now be possible to pack approximately 15,000 32-bit integer samples with full system meta-information inside of 512k.
> > - Make system (make.py) completely restructured to use module-based auto-dependency system and settings transformation system. Many pathing fixes for Windows environment. See: make.py and tools/build/build_zip.py;
> > - Changed all manager classes (e.g. DeviceDriverManager, ChannelManager, etc.) to use an AbstractServiceManager base class used in src/common/abstract_service_manager.py
> > - Added services sub-system with ServicesManager where users may start their own managed services within the context of a Dia application. Services now contain the ability to stop and remove running instances; although this functionality is still not exposed to any external presentations. See: src/services
> > - Added ability to remove channels from a running system on the fly.
> > - Added “SettingsContext” class to Settings sub-system to allow objects to query, modify, and apply settings on a running system programmatically. See: src/settings/settings_base.py
> > - Refactored the Channels layer to more cleanly represent the design philosophy of the system. The delegation of responsibilities between Channels and ChannelSources (such as ChannelSourceDeviceProperty) should be more cleanly represented.
> > - Added common/helper/parse_duration.py Converts strings like ‘5 min’ or ‘1 hr 20 sec’ to msec (or other) to simplify configuring durations under Dia. Supports [‘ms’,’sec’,’min’,’hr’,’day’]
> > - Included digi_serial.py module based on “PySerial” in lib/digi_serial.py
> > - Included digi_ElementTree.py module based on “ElementTree” in lib/digi_ElementTree.py
> > - Re-wrote src/common/digi_device_info.py to use ElementTree to be more robust.
> > - All modules which tried to “import zigbee” now attempt to “import xbee” as a first priority as the “zigbee” module has been deprecated in new Digi firmware releases.

> Device Changes:

> > - Added XBee Auto-Enumeration Device capable of automatically adding discovered XBee devices, and their channels, to the system. See: src/xbee/xbee_devices/xbee_autoenum.py See also: demos/autoenum

> > - Restructured all XBee device drivers to inherit from XBeeBase (see src/xbee/xbee_devices/xbee_base.py) in order to support auto-enumeration and promote code reuse.

> > - Rewrote DDO parameter caching mechanism for XBeeDeviceManager; speeds up XBee node configuration.

> > - XBeeDeviceManager now maintains its own node list. This node list is used to comprehend the network topology. The XBee network topology is used when setting up sleeping networks (when using XBee ZNet or ZB modules) to ensure that the sleep parameters are set correctly. Sleep parameters are now distributed via unicast instead of broadcast. This is much more network efficient, especially for large networks.

> > - Added XBeeDisplay device driver and supporting files. See: src/devices/xbee/xbee_devices/xbee_display.py

> > - Added SettingsDevice, a channel-oriented way of querying, modifying, and persistently saving Dia settings on a running system. See: src/devices/settings_device.py

> > - Added example XBee Serial Devices, loopback and terminal. These device drivers are suitable for testing and educational purposes to allow individuals to more easily create their own custom devices. See: src/devices/xbee/xbee_devices/xbee_serial*.py

> > - Added support for local DIO/AIO capability of ConnectPort X4 NEMA products. See: src/devices/xbee/xbee_devices/xbee_local_(a|d)io.py

> > - Added device property option to allow device writers to specify certain channels to never be logged. Option is called DPROP_OPT_DONOTLOG See also: src/channels/channel.py

> > - Renamed ‘lux’ unit to ‘brightness’ for all Digi light sensors to reflect that they are non-calibrated, non-linear values.

> > - Added YML settings for XBee Sensor driver

> >   - degf to convert temperature to Fahrenheit (“F”) instead of “C”
> >   - trace to show/suppress the printf for normal I/O samples
> >   - temperature_adjust / humidity_adjust / light_adjust as floats for simple offset calibration, which enables multiple XBee Sensor units to provide more consistent readings

> >   Clean up the printf trace (when trace: “On”) to be more user friendly

> > - In the AIO driver,

> >   - Removed the alarm on battery, as it causes serious problems in new AIO
> >   - Add ability to turn ‘off’ unused channels, just means Dia ignores them (to use, set “channel_mode: Off” instead of TenV, etc)
> >   - fixed the 0-10v calculation (Vantive)
> >   - add ability to return the raw binary values in case external linearization works more cleanly with 0-1024 than floats etc

> >   Clean up the printf trace (when trace: “On”) to be more user friendly

> > - Changed “sample_time_ms” setting in XBee Digital I/O driver to “sleep_time_ms”

> > - Various fixes and enhancements to Massa M3 and M300 drivers. See: src/devices/vendors/massa

> > - Added device from RCS (TZB43 Thermostat). See: src/devices/vendors/RCS

> > - Fixed with XBeeDeviceManager’s “skip_list” setting wherein node addresses may not be specified in mixed case hexadecimal.

> Presentation Changes:

> > - Renamed cwm_exist Presentation to idigi_db. Added “secure” setting to upload data via HTTPS.
> > - idigi_db now includes “compact” setting to generate more-compact XML–in order to save some bandwidth–by using attributes instead of start and end tags.
> > - Added XBeeDisplay presentation with widgets and a layout manager: See: src/presentations/xbee_display/list_details.py
> > - Modified SMTP presentation to use threading.Thread and host name resolution for server addresses.
> > - Logging support added to Console, XML-RPC, and RCI interfaces.
> > - Added ‘channel_info’ command to Console, XML-RPC, and RCI interfaces.
> > - Small parsing and robustness fixes to Console Presentation.

> Services:

> > - Added software watchdog in src/services/watchdog_service.py

> Demonstrations:

> > - Added XBee Auto-Enumeration demo to demos/autoenum

Release Notes for Version 40002675_B1 (1.1.15):

> - Fixed make.py problems when Dia configuration (.yml) files are located outside of the cfg directory.

> - Increased compatibility with generating Dia applications under Cygwin.

> - Excluded unreleased and experimental driver modules from API reference documentation.

> - Fixed fatal exception caused by having no configured devices or presentations.

> - Modified several demo configuration file’s presentation sections to use the web page “idigi_dia.html”

> - Changed the default file name of the file logger to “idigi_dia.log”

> - Fixed XBeeConfigBlockSleep to detect XBee ZB module router firmware versions which do not support the “SM” parameter. If the parameter is set to 0 (SM_DISABLED) the block will be marked as completed without having to attempt any DDO.

>   The XBIB XBee development board driver now functions correctly with the 2141 ZB firmware shipped with the iDigi Starter Kits.

> - Removed internal DD DDO parameter cache in favor of caching all over- the-air configuration commands.

> - Modified configuration queuing of sleeping end devices to defer their first configuration attempt for one complete deferment cycle. This gives nodes a chance to report in autonomously and be processed for configuration interruptively resulting in a net faster configuration cycle.
