Notes for firmware 3.12.0:

The number of different font sizes in the `Custom font sizes` patch has increased from 24 to 40 in this firmware version.

When reading kepubs with a low line spacing setting, a partial line of text can appear at the top or bottom of a page. To avoid this it is necessary to increase the line spacing a bit. See this screenshot for example, and see this post for what I think is causing the problem.


More patches for firmware 3.12.0:
If you know of any more patches for firmware 3.12.0 post them in this thread and I'll add them to this list:


The custom reading footer patch in the attachment to post #1 has a new layout: there are now three seperate patches for Touch/Mini, Glo/Aura, AuraHD/H2O; each patch has six example footer sizes.

Here is the old style patch (libnickel.so.1.0.0.patch):

Spoiler:

<Patch>
patch_name = `Custom reading footer style`
patch_enable = `yes`
replace_string = E359A4, `ReadingFooter {\n\tmin-height: 70px;\n\tmax-height: 70px;\n\tqproperty-footerMargin: 105;\n}\n\nReadingFooter[qApp_deviceCodeName="phoenix"] {\n\tmin-height: 82px;\n\tmax-height: 82px;\n}\n\nReadingFooter[qApp_deviceCodeName="dragon"] {\n\tmin-height: 120px;\n\tmax-height: 120px;\n\tqproperty-footerMargin: 170;\n}\n\n* {\n\tfont-size: 16px;\n}\n\n[qApp_deviceCodeName="phoenix"] {\n\tfont-size: 20px;\n}\n\n[qApp_deviceCodeName="dragon"] {\n\tfont-size: 26px;\n}\n\n[qApp_localeName="ja_JP"] {\n\tfont-family: A-OTF Gothic MB101 Pr6N;\n}`, `ReadingFooter {\n\tmin-height: 70px;\n\tmax-height: 70px;\n\tqproperty-footerMargin: 105;\n}\n\n* {\n\tfont-size: 16px;\n\tpadding-bottom: 0px;\n\tmargin-top: 0px;\n\t/*font-family:none;*/\n}\n\n[qApp_localeName="ja_JP"] {\n\tfont-family: A-OTF Gothic MB101 Pr6N;\n}`

# Uncomment the replace_string lines of one of the examples below, comment out
# the rest. If you choose to make further changes to the examples, BE CAREFUL
# NOT TO ALTER THE LENGTH OF THE REPLACEMENT STRINGS! (Add or remove spaces if
# necessary to keep the total length the same.)
#
# Example for Touch/Mini:
#replace_string = E359B5, `min-height: 70px;`, `min-height: 32px;`
#replace_string = E359C8, `max-height: 70px;`, `max-height: 32px;`

#replace_string = E35A28, `margin-top: 0px;`, `margin-top: 0px;`

# Example for Glo/Aura:
#replace_string = E359B5, `min-height: 70px;`, `min-height: 40px;`
#replace_string = E359C8, `max-height: 70px;`, `max-height: 40px;`

# Example for AuraHD/H2O:

#replace_string = E359C8, `max-height: 70px;`, `max-height: 50px;`

#replace_string = E35A12, `padding-bottom: 0px;`, `padding-bottom: 8px;`
#replace_string = E35A28, `margin-top: 0px;`, `margin-top: 0px;`
#
# Uncomment one of the following if you wish the footer to use a fixed font.
# (And enable one of the Custom header style patches below with the same font.)
#
#replace_string = E35A3A, `/*font-family:none;*/`, `font-family:  Amasis;`
#replace_string = E35A3A, `/*font-family:none;*/`, `font-family:  Avenir;`

A patch to always (or never) turn on kepub hyphenation, regardless of justification setting. (libnickel.so.1.0.0.patch):

Spoiler:

<Patch>
patch_name = `Set kepub hyphenation`

# The built-in kepub stylesheet has a line "* { -webkit-hyphenation: auto; }"
# to turn on hyphenation, but it is only used if the device's justification
# button is set to full justification. With this patch enabled hyphenation
# will always/never be turned on, regardless of justification button setting.
#
# (Note that if the publisher has set the hyphenation in the book's stylesheet
# then that will override the built-in stylesheet.)
#
# Alternative 1: Always turn kepub hyphenation on
