[GeoffR]

Notes:

There is a new patch:
* `Default ePub serif font (Georgia)` (in librmsdk.so.1.0.0.patch)

Kobo have changed the default fonts in the ePub reader, which might cause some problems for some books and some devices when selecting the "Publisher Default" font or when reading or processing ePub books where the publisher forced use of the generic "serif" or "san-serif" fonts. Enable the following patches to return to the fonts used in previous firmware versions, which appears to solve the problem:
* `Default ePub serif font (Georgia)` (in librmsdk.so.1.0.0.patch)
* `Default ePub sans-serif font (Avenir)` (in librmsdk.so.1.0.0.patch)

(Edit: Kobo have now stopped the rollout of this firmware version, perhaps because of the above problem.)

There may be a problem with the `Allow searches on Extra dictionaries` patch in this version. See discussion starting with post #15 and post #16

Here is a list of the patches in each .patch file. Where there is a group number to the left, only one patch from each numbered group can be enabled:
