Hi all,
We are keen to share our plans with you after our iteration planning day
this week. This turns out to be quite a long post, but should provide a
good overview on whats cooking.
2015 will see Sailfish OS evolve towards a display resolution and form
factor independent operating system capable of running on a range of
devices. It will also bring a renewed Sailfish UI. We plan to demo this
evolution at the Mobile World Congress in March.
We have now started to work full speed on the new UI framework changes
and are currently in the prototyping phase. Our main driver is to
introduce changes that
1. enhance user experience on both the phone and tablet
2. strengthen the OS core
3. simplify implementation for a better managed code base
Here is a list of things we are trying out w.r.t the new UI framework:
* improved notifications system
* richer Events View with more widgets and actions
* separating lock screen from the home screen for simplified UX and
technical architecture
* home screen interaction improvements with revamped navigation hierarchy
We have progressed quite well in the direction of Sailfish UI
scalability already, for example we have the following implemented in
our internal development branch:
* scalable icons
* home screen and application layouts take physical display dimensions
into account, for example larger displays are able to show more content
* display-size optimised graphical effects
During this month we'll continue adapting ambience wallpapers to
different display sizes and aspect ratios.
Our next big UI task is to enable landscape mode in apps, system
dialogs, active covers, and optimise the design for the best use of the
additional space.
On the platform level, in this iteration we are working towards the
following goals:
* System update improvements (will be utilised for update 12 onward):
- run btrfs balance operation before installing OS update - Part of
https://together.jolla.com/question/66595/request-automaticbackground-btrfs-balance-defrag-type-cleaning-of-filesystem/
- enablers to allow factory reset operation to reset the OS to the
latest available public version instead of the age old factory image
provide an API to check the system update size
- enablers to allow store client to handle downloading the OS update in
the background without interfering with the user
- upgrade to using latest upstream versions of libzypp and zypper to
get new features (to allow us to later take them into use, namely better
pattern support and conflict calculations)
* Adaptation work for the tablet:
- make Jolla tablet turn on promptly and give understandable
progress/status information
- design and implement filesystem layout
- check power management functionality on the tablet
- bring bluetooth related fixes to tablet kernel
Sensor detection, USB and camera adaptation
- check stereo speakers functionality
- check iphb wakeups functionality on the tablet
- ensure USB charging works
* adapt middleware to modemless device i.e. tablet
* work towards Pulseaudio 6.0
* drop upower in favour of statefs - this has been in plans for a while
and we are now on it as fixing issues on upower is not the best use of
our efforts
* dual-stack implementation (ipv4 and ipv6) for cellular connectivity
* prototyping excrypted filesystem
* research SELinux as a solution for system security and application
access control
* toolchain updates - we are working towards upgrading to GCC 4.8,
binutils 2.25, switch to Thumb2+NEON for ARM by default, march=i686 and
SSE2 minimum for X86
* Performance improvements:
- continue to analyze memory usage and chopping off bits wherever
possible
- work on a benchmarking tool to measure progress <- this may not
happen (yet or completely) due to priority shifts
- continue work on the QML engine and forking to save memory
As you may notice, there is lots to do in the lower levels and
middleware to take the OS to the next stage. Nevertheless, we are keen
to continue provide new features where and when bandwidth permits. In
the next update we intend to release:
* renewed browser UI - simplified tab view, search for word on webpage,
user friendly toolbar and URL field -
https://together.jolla.com/question/4197/search-in-browser/
* weather info integration to events view (Foreca) -
https://together.jolla.com/question/1967/weather-application/
* option to customise the highlight color of your favourite ambience in
ambience settings (in Gallery app)
* notification to the user if there is insufficient disk space (< 500MB)
while attempting to upgrade the OS
* allow editing of mobile data setting always (currently if the device
is in roaming and data roaming is set to "Do not allow", mobile data
settings are disabled)
In the spirit of supporting the community TOHkbd project, we have also
implemented keyboard slide policy that will guide the display
(un)blanking behaviour when sliding the hardware keyboard in/out.
During this month, we have planned to work on the following features:
* private browsing
https://together.jolla.com/question/1821/private-mode-in-web-browser/
* lock screen media player controls
https://together.jolla.com/question/3414/control-music-from-the-lock-screen/
* enable USB tethering in the UI
https://together.jolla.com/question/3798/usb-tethering/
* IMAP idle/push support
https://together.jolla.com/question/493/imap-idle-imap-push-for-the-e-mail-app/
Not to mention that bug fixing is part of our daily work and will carry
on in parallel with all of the above activities. Sailfish OS updates
will continue to be delivered frequently.
Due to the nature of the tasks at hand, the gap between releases may
vary. It does not imply that we are intentionally slowing down -- on the
contrary, we are ramping up with extreme dedication in the next few
months to deliver a scalable, refreshed and coherent platform, requiring
time and focus to make things right. In order to better support our
goals, our internal QA setup has been further enhanced to allow working
on multiple releases in parallel and keep release instances longer for
possible updates at a later point in time.
In a nutshell, we are excited to work towards the new horizon and will
continue to share our progress with you. Cheers!
