v2.1.0
Google is now sending me an email each time a user asks for a refund. There's no info on who cancelled or why, and Google handles all the transactions, so it's only noise. But it does give me an incentive to improve :)
There's a new locked option under Appearance called Display Options. You can use it to hide the left panel or display alternate content (for the clock widget)
If the unlocker is uninstalled, the widget will now return to the default appearance on the next refresh

v2.0.0:
New feature: Much improved management of news feeds. Support for Google News, including custom subjects. Just create a custom Google News feed and enter the keyword 'android' for example, and you get a feed with Android news articles drawn from all of Google's many sources.
More fiddling with calendar time zones. Seems my 'quick fix' for v1.9.1 was just a tad too quick.

v1.9.0:
More efficient use of cache when Android re-starts the widgets after killing it temporarily
Fixed a calendar time zone bug
New icon, to match the ICS version

v.1.8.1:
Fixed custom background color bug for the paid version of the All-In-One Widget. Sorry about that!

v1.8.0:
Re-worked caching again. As per numerous requests, the cache is no longer cleared by background updates. If a weather update fails, for example, the widget will continue to show the data from the previous update. This should result in far fewer question marks and "no news available" messages.
I removed a few features from the calendar widget: The 'auto-reset' and the 'scroll by page' is gone. Also, it is no longer possible to scroll the calendar backwards from 'now' to 'next year'

V1.7.1:
- Bug fixes, mainly for the forecast dialog.

v1.7.0:
This is a rather large update, but it contains mostly behind-the-scenen changes in order to prepare the code base for the "Tablet Edition" of the GlassWidgets. The Tablet Edition is released as a separate App for now, and requires Android 3.1 and up.
I've moved the hidden "refresh" button to the lower left corner of the widgets as well as changed the handling of small screen sizes.

v1.6.3:
Since v1.6 I've received some error reports from users having trouble with the calendar. I think I've localized and fixed the problem, but I've been unable to recreate it on my phone for final testing. If you've had this problem, I would appreciate if you could let me know if the fix was successful.

v1.6.2:
A couple of minor bug fixes for the calendar widget

v1.6.1:
A bugfix for the forecast dialog.

v1.6:
This is a behind-the-scenes update. I replaced the in-memory cache with a database-based cache that should prevent the widgets from randomly "forgetting" things whenever Android feels like cleaning up the memory.

v1.5.1:
Fixed the news feed preference for the All-In-One widget.
Thanks Miko!

v1.5:
Adds the All-In-One widget. Improves the handling of city names containing special characters (like Poznań, PL for example). Changed the widget icon to match the one for my new Glass AppLauncher App.

v1.4.3:
Better support for addresses in Canada (the admin area is included, ex. "British Columbia").

v.1.4.2:
Yet another bug fix for the geolocation feature. Now the widget always requests addresses in English, which results in much better support for addresses in non-English speaking locales.

v.1.4.1:
This is the first larger upgrade in a long time.
It (finally) adds geolocation support for the clock & weather widget, the option to show the titles of RSS/Atom feeds in the news widget, as well as a few bug fixes.

v1.4:
This is the first larger upgrade in a long time.
It (finally) adds geolocation support for the clock & weather widget, the option to show the titles of RSS/Atom feeds in the news widget, as well as a few bug fixes.

v.1.3.4:
It seems that Google keeps changing the weather data format. The forecast dialog lost the icons again. This is (another) quick fix. The icons are now back to normal.

V1.3.2:
Not much happening at the moment. Been busy with my day job as well as other projects. Sorry.
But I think I finally got a handle on the old problem with the calendar widget, where it sometimes showed an event from yesterday. Woohoo!
