"This update automatically downloads and installs on your Kindle Touch when connected wirelessly; however, you can also manually download the software and transfer the update to your device via USB cable.
The software update includes general improvements and the following feature enhancements:"
' Improvements when buying from a book sample
While reading a sample of a book, you can view the price of the full book and purchase from the reading toolbar with one tap.
View full definition when looking up a word
When you look up a word in the dictionary, you can now view the full definition in the definition window.
You can easily search for a highlighted word or phrase in your book, your items, or in the Kindle Store. Highlight the word or phrase, tap More, and then tap Search. '
If you have a version prior to 5.3.2 and you don't want to wait for the update to arrive on your Kindle Touch and prefer to do it manually yourself, Amazon links you to the appropriate earlier update that must be downloaded and installed before doing the 22.214.171.124 update.
How to determine your software version
From Home, tap Menu and then tap Settings.
On the Settings screen, tap Menu (the Amazon update page omits a step here) and THEN select Device Info. Your software version is listed under Firmware Version.
The Kindle Touch Software update page ( US here, UK here ) leads you through what to do, depending on which Firmware Version is showing for your KTouch.
Again, Amazon will be delivering this update over Wi-Fi. Customers who prefer to receive the update immediately can instead manually download the software and transfer the update to the device via USB cable.
The software-update page for Kindle Touch: USUK
This one is most noted in press reports for the new ability -- while using this app for iPad and iPhone/iPod Touch -- to search for free Kindle book samples and access a link in the downloaded sample for the Amazon product page for that book while still in the app, without having to get out to Safari -- not officially mentioned). You can email yourself that link.
Believe it or not, I don't necessarily agree Apple should be forced to allow this, but I also feel that they should not take 100% (!) of the app-maker's commission either, as had been their policy of taking 30% of an E-book vendor's selling-price (not vendor's profit amount) for in-app store-links under Apple's Agency model (no longer in play for ebooks though, for a couple of years, after Apple lost the lawsuit), which would be the entire Amazon or Barnes and Noble commission on an e-book.
Tom also mentions the not-listed feature of "some level of KF8 reflowable support" in v3.9, and he discovered that it was also there in the Kindle for iOS v3.8.1 app, crediting Nate Hoffelder in his TheDigitalReader article on the new v3.9 update.
Here are the official features as announced in the Amazon Kindle forum by Kevin G, the Community Manager there.
' What's New in Version 3.9?
* Kindle Free Sample Search - From the existing Library Search, customers can now search Amazon's catalog of millions of Kindle books and download free samples from within the app. New books are easier than ever to find.
* Bring Your Own Dictionary - Customers can now use previously purchased Dictionaries, such as medical, legal, or other translation references to define words in any of their other eBooks. Dictionaries downloaded to the device automatically appear in the selection list. [ ab here: This is GREAT! ]
* Accessibility Quick Reference - Accessibility gestures for blind and visually impaired customers are included for quick reference and can be found under the FAQ section in settings. The guide has been translated for all supported languages.
* Instant Cover Loader - Book cover art displays quicker and more fluidly.
* Bug Fixes/Stability Improvements
Do take a look at that announcement message thread, as it has a LOT of customer feedback on this update along with help given there.
Kindle Fire software update that's due soon
With reference to the follow-up article with workarounds for an over-the-air software update version [x]4.5 sent to a few customers but not placed on the servers for manual installation, the glitches reported with Flash video when using web browsers like Dolphin browser have been fixed, as shown by an unofficial interim update [x]4.6 which has been, in effect, sent to those who got the wirelessly-sent update (limited distribution to a few) but reported glitches, and there's general rejoicing involved.
This means it's likely due soon on the servers. It is said to work also with the Time to Read bugginess some were experiencing. Kudos to Amazon Kindle Team for working with the customers this way.
