Thank you everyone who helped us test Bloom 5.1 while it was in Beta. It is now the Release.
Hereâs whatâs new in 5.1:
Collection Tab
You can now rename a book. Previously, Bloom always used the name of a bookâs title. The new name appears under the thumbnail of the book and also the name of the folder on disk (see animation). Feature Request
Edit Tab
You can create hyperlinks that point to other pages in the same book. This can be used for creating your own simple Table of Contents. When creating ePUBs, these links will be turned into normal text because the feature does not work in ePUBs. Feature Request
Duplicate Page Many Times. You can now enter a number to make many duplicates of a page all at once (see animation).
We made several fixes to the checks in Decodable and Leveled Readers.
Leveled Reader
We added a visual notification when pages have too many sentences.
We improved how we count words in complex pages (such as arithmetic pages).
Overlay Tool (Bloom Enterprise)
The Overlay Tool can now add videos Feature Request
The Overlay Tool can now add images on top of the image Feature Request
(See an animation of these new overlay features)
Team Collections (Bloom Enterprise)
Team Collections are a new feature that helps you safely share a collection within your team, across the internet, without full-time internet access. For this release, weâre going to keep this feature behind the âExperimentalâ checkbox. For now, we are only supporting Dropbox & LAN environments. Please contact us if you are considering using this. We need your help to fully understand how this will be used, and how the experience goes.
About Bloomâs use of Dropbox
People will be naturally resistant to installing Dropbox. There are two things that may help them. First, once Dropbox is set up, you will not have to actually learn to use Dropbox, as it just sits in the background for Bloom to use, invisibly. Second, we are starting with Dropbox support because it is far superior to Google Drive in one crucial way: when you make a small change to a book, Dropbox will send just a small amount of data over the internet to your teammates. In contrast, Google Drive will send the entire book: all the text, images, recordings, videos, activities, etc. Because we want this feature to work well in environments with slow or expensive internet, we, therefore, decided to put our initial efforts into supporting Dropbox. In the near future, we will attempt to make Google Drive an option for teams with great internet.
Team Collections debuted in Bloom 5.0 beta. For 5.1, we have added a few small features:
We added a basic History tab to the Team Collection dialog. It currently only tells you the history of check-ins (who edited the book, when). We will be adding more history in future versions.
We added a little informational menu option that provides information about the name and âavatarâ (picture) associated with books you check out. The dialog also provides links for changing (or setting) the avatar and name.
You can now âForget Changes & Check in Bookâ if you decide to abandon the changes youâve made to a book since you checked it out.
Images
We have removed, from the lower-left corner of images, the button that opened the âImage Description Toolâ. We did this because of reports that users were clicking on it, not understanding what was happening and then entering their story text into the image description box. Authors making books for the blind can still use this tool, of course. You just wonât have this convenient shortcut anymore. Feature Request
When Bloom has trouble loading an image and you send us an error report, we now will receive the offending image file. That will help us figure out what the problem is.
Publish Tab
We added a new tool for making it easy to create a BloomPUB of every book in a collection, with a single command. (Bloom Enterprise)
You can now also upload an entire collection or even multiple collections to the Bloom Library. (Bloom Enterprise)
Bloom Library
We improved counts and stats on Bloom Library. For example, a collection that contains child collections can now display the total count (example).
We added the ability for a project to list its sponsors at the bottom of the page (example).
We added a new page selector for Bloom Player, the engine that powers book reading in Bloom Reader, BloomLibrary.org, and embedded Reading App Builder books. 
Other Good Stuff
Faster Enterprise Subscription Delivery When projects get a new Enterprise subscription, there is a delay while we build their branding pack (logos, boilerplate text, etc). Starting with Bloom 5.1, customers donât have to wait⌠their Enterprise code will work immediately. Bloom will show a placeholder message on the back cover that shows the subscription name. When an update to Bloom contains the branding files for the subscription, this message will be automatically replaced with the branding images, the next time the books in the collection are edited.
Work towards a more cross-platform Bloom
As with most versions, we did a bunch of behind-the-scenes work towards rewriting making Bloom be more portable to other operating systems. For the most part, you wonât be able to tell the difference.
Reminder for SILers
Most SIL projects can freely use the SIL internal Enterprise License. Questions? Please shoot us an email at enterprise (preposition) bloomlibrary.org.
Upgrading
If you are using Bloom 5.0 Release, Bloom should automatically ask to update itself. Otherwise, you can get 5.1 from the Bloom downloads page. As usual, you can have the Release & Beta versions installed at the same time , and open books in either one.
