Release Notes</h1></div></div></div><div class="simplesect"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="idp59035888"></a>Version 1.41</h2></div></div></div><p>
+ Version 1.4.1 is a minor release. It fixes install issues on
+ Windows and provides the missing TeleMetrum V2.0 firmware. There
+ aren't any changes to the firmware or host applications at
+ all. All Windows users will want to upgrade to get the signed
+ driver, but Mac and Linux users who do not need the TeleMetrum
+ V2.0 firmware image will not need to upgrade.
+ </p><p>
+ Windows Install Fixes
+ </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
+ Provide signed Windows driver files. This should avoid any need to
+ disable driver signature checking on Windows 7 or 8.
+ </p></li><li class="listitem"><p>
+ Fix Java version detection and download. Previously, the
+ installer would only look for Java 6 or 7 and insist on
+ downloading its own Java bits if there was something else
+ installed. Furthermore, the 64-bit Java link provided didn't
+ work for anyone other than Keith, making it impossible to
+ install AltOS on any machine with Java SE 8 installed.
+ </p></li></ul></div><p>
+ </p><p>
+ Other Fixes
+ </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
+ Include 1.4 firmware for TeleMetrum V2.0. None of the
+ installers shipped this file. Now it's included in the AltOS
+ packages for Linux, Mac and Windows.
+ </p></li><li class="listitem"><p>
+ Include Google Application Key for map downloading. The 1.4
+ release didn't have this key in the released version of the
+ software, making map downloading fail for most people.
+ </p></li></ul></div><p>

+ Version 1.4 is a major release. It includes support for our new
+ TeleGPS product, new features and bug fixes in in the flight
+ software for all our boards and the AltosUI ground station
+ </p><p>
+ AltOS New Features
+ </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
+ Add support for TeleGPS boards.
+ </p></li><li class="listitem"><p>
+ Replace the 'dit dit dit' tones at startup with the current
+ battery voltage, measured in tenths of a volt. This lets you
+ check the battery voltage without needing telemetry, which
+ is especially useful on EasyMini.
+ </p></li><li class="listitem"><p>
+ Change state beeping to "Farnsworth spacing", which means
+ they're quite a bit faster than before, and so they take
+ less time to send.
+ </p></li><li class="listitem"><p>
+ Make the beeper tone configurable, making it possible to
+ distinguish between two Altus Metrum products in the same ebay.
+ </p></li><li class="listitem"><p>
+ Make the firing time for extra pyro channels configurable,
+ allowing longer (or shorter) than the default 50ms. Only relevant
+ for TeleMega at this time.
+ </p></li></ul></div><p>
+ </p><p>
+ AltOS Fixes
+ </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
+ Fix bug preventing the selection of the 'Flight State After'
+ mode in pyro configuration.
+ </p></li><li class="listitem"><p>
+ Fix bug where erasing flights would reset the flight number
+ to 2 on TeleMega and TeleMetrum v2.
+ </p></li><li class="listitem"><p>
+ Fix u-Blox GPS driver to mark course and speed data as being
+ present.
+ </p></li></ul></div><p>
+ </p><p>
+ AltosUI New Features
+ </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
+ Add zooming and new content types (terrain and road maps) to
+ map view. Change map storage format from PNG to Jpeg, which
+ saves a huge amount of disk space. You will need to
+ re-download all of your pre-loaded map images.
+ </p></li><li class="listitem"><p>
+ Add a distance measuring device to the maps view. Select
+ this by using any button other than the left one, or by
+ pressing shift or control on the keyboard while using the
+ left button.
+ </p></li><li class="listitem"><p>
+ Add new 'Ignitor' tab to the flight monitor display for
+ TeleMega's extra ignitors.
+ </p></li><li class="listitem"><p>
+ Increase the width of data lines in the graphs to make them
+ easier to read.
+ </p></li><li class="listitem"><p>
+ Add additional ignitor firing marks and voltages to the
+ graph so you can see when the ignitors fired, along with
+ the ignitor voltages.
+ </p></li><li class="listitem"><p>
+ Add GPS course, ground speed and climb rate as optional
+ graph elements.
+ </p></li></ul></div><p>
+ </p><p>
+ AltosUI Fixes
+ </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
+ When flashing new firmware, re-try opening the device as
+ sometimes it takes a while for the underlying operating
+ system to recognize that the device has rebooted in
+ preparation for the flashing operation.
+ </p></li><li class="listitem"><p>
+ Hide Tilt Angle in ascent tab for devices that don't have a gyro.
+ </p></li><li class="listitem"><p>
+ Filter out speed and acceleration spikes caused by ejection
+ charge firing when computing the maximum values. This
+ provides a more accurate reading of those maximums.
+ </p></li><li class="listitem"><p>
+ Fix EasyMini voltage displays. Early EasyMini prototypes
+ used a 3.0V regulator, and AltosUI still used that value as
+ the basis of the computation. Production EasyMini boards
+ have always shipped with a 3.3V regulator. Also, purple
+ EasyMini boards sensed the battery voltage past the blocking
+ diode, resulting in a drop of about 150mV from the true
+ battery voltage. Compensate for that when displaying the
+ value.
+ </p></li><li class="listitem"><p>
+ Display error message when trying to configure maximum
+ flight log size while the flight computer still has flight
+ data stored.
+ </p></li><li class="listitem"><p>
+ Handle TeleMetrum and TeleMini eeprom files generated with
+ pre-1.0 firmware. Those ancient versions didn't report the
+ log format, so just use the product name instead.
+ </p></li></ul></div><p>
+ </p><p>
+ TeleGPS Application
+ </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
+ New application designed for use with TeleGPS boards.
+ </p></li><li class="listitem"><p>
+ Shares code with AltosUI, mostly just trimmed down to focus
+ on TeleGPS-related functions.
+ </p></li></ul></div><p>
+ </p><p>
+ Documentation changes
+ </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
+ Re-create the drill template images; they should print
+ correctly from Firefox at least. Ship these as individual
+ PDF files so they're easy to print.
+ </p></li><li class="listitem"><p>
+ Add a description of the 'Apogee Lockout' setting, which
+ prevents the apogee charge from firing for a configurable
+ amount of time after boost.
+ </p></li></ul></div><p>
