+## v0.9 (2017-01-17)
+
+The "Locker" part of the name was not intuitive. To help remedy this a new application icon was created by betsythefc which better represents the purpose of the application: to store loyalty cards which use barcodes. Along with this new icon the name of the application has been changed to "Loyalty Card Keychain".
+
+Additional features/improvements:
+
+- Importing/Exporting cards was changed to be more flexible. (https://github.com/brarcher/loyalty-card-locker/pull/76)
+- Translations for Lithuanian added. (https://github.com/brarcher/loyalty-card-locker/pull/62)
+- Translations for French added. (https://github.com/brarcher/loyalty-card-locker/pull/80)
+
+## v0.8 (2016-11-22)
+
+New features/improvements:
+- Screen brightness increased to its maximum when displaying a card, to help barcode scanners successfully capture the barcode. (https://github.com/brarcher/loyalty-card-locker/pull/54)
+- Add a delete confirmation when deleting a card. (https://github.com/brarcher/loyalty-card-locker/pull/55)
+- Add translations for German (https://github.com/brarcher/loyalty-card-locker/pull/57) and Czech (https://github.com/brarcher/loyalty-card-locker/pull/58).
+- Clarification change for Italian translation. (https://github.com/brarcher/loyalty-card-locker/pull/66)
+
+## v0.7 (2016-07-14)
+
+New features/improvements:
+- Long-click of a card brings up option to copy card ID to the clipboard. (https://github.com/brarcher/loyalty-card-locker/issues/49)
+
+Bug fixes:
+- Back button on Input/Export view now works, moving user to main view
+
+## v0.6 (2016-05-23)
+
+New features/improvements:
+- Allow user to enter barcode manually. If a user elects to enter a barcode manually, a list of all valid and supported barcode images is displayed. The user then may select the barcode image which matches what the user wants. https://github.com/brarcher/loyalty-card-locker/issues/33, https://github.com/brarcher/loyalty-card-locker/pull/44 
+
+Bug fixes:
+- Resolve issue where some displayed barcodes were blurry. (https://github.com/brarcher/loyalty-card-locker/issues/37)
+
+## v0.5 (2016-05-16)
+
+New features/improvements:
+- An about dialog can be opened from the main screen, which gives details about the application and project on GitHub (https://github.com/brarcher/loyalty-card-locker/issues/19)
+- Allow loyalty card information to be imported from/exported to a CSV file in external storage (https://github.com/brarcher/loyalty-card-locker/issues/36 https://github.com/brarcher/loyalty-card-locker/issues/20)
+
+## v0.4 (2016-04-09)
+
+New features/improvements:
+- Dutch translation
+- Allow name field to be editable after adding loyalty card
+- Add an optional note field
+
+Bug fixes:
+
+- Resolve all issues identified by FindBugs and require all FindBugs issues be resolved prior to pull request acceptance
+
+## v0.3 (2016-02-11)
+
+- Now officially supports the following list of 1D and 2D barcodes:
+  * AZTEC
+  * CODABAR
+  * CODE_39
+  * CODE_128
+  * DATA_MATRIX
+  * EAN_8
+  * EAN_13
+  * ITF
+  * PDF_417
+  * QR_CODE
+ * UPC_A
+- Generated barcodes are larger, easier to scan from a scanning device
+
+## v0.2 (2016-02-07)
+
+- Italian translations
+- Support for all 1D barcode types. (Originally only product 1D barcodes were supported)
+- Add required camera permission, which was initially missing.
+
+
+## v0.1 (2016-01-30)
+
+- Ability to create/edit/delete loyalty cards
+- Capture barcode of loyalty card using a camera
+- Display captured barcode, for scanning at a store
