v0.9

Note

This release may not be available on KoboPatch Web UI yet as further testing is done before general availability via that platform.

Documentation

• Clarified shared fix dependencies, process-wide text shaping, rendering test limits, and the boot failsafe's recovery window.

Added

• Development builds include a source fingerprint in their version and log lines, distinguishing them from release builds and earlier uncommitted edits.
• Long chapters open several times faster. The reader now uses Qt's newer text shaper and remembers text it has already shaped.
• Long chapters open faster again. WebKit used to lay a chapter out twice and throw the first one away; that pass is now skipped.
• Opt-in: set ntf_more_spacing:1 to use 24 line-spacing choices instead of the stock 15, running from 0.80 to 1.50. Disabled by default.
• Small caps in a book now use the reading font's own small cap glyphs when it has them, with the font's kerning, instead of capitals shrunk to 70%. Needs optimizeLegibility; fonts without small caps are unchanged.

Fixed

• The log rotates during a running session before a write would exceed 256 KiB, instead of growing until the next restart.
• Narrow custom line spacing no longer clips text or pushes paragraphs onto separate pages.
• Fixed an integer overflow in the capital-spacing fix's font-table bounds check.
• The reader-font quoting fix now skips font-family: text that sits outside a CSS declaration instead of quoting across rule boundaries.

v0.8

Note

This release may not be available on KoboPatch Web UI yet as further testing is done before general availability via that platform.

Added

• Fonts with numbers in their names now apply correctly.
• Page boundaries no longer clip lines of text in kepub books.
• Centred images stay centred when the reader's text alignment changes.
• Oversized drop caps no longer increase the spacing between the first two lines of a paragraph.
• Development builds include page-layout diagnostics for bug reports.

Fixed

• The letter-spacing fix now applies when both justification fixes are disabled.
• The reader-font fallback fix works again.
• A failed startup now removes every installed hook.

Improved

• The supported firmware range now starts at 4.23.15505.
• Updates add new settings to existing config files automatically.
• The log rotates after it reaches 256 KB.
• The startup log lists which fixes are enabled and active.

v0.7

Added

• Letter spacing now applies to spaces between words.
• Capital spacing no longer affects ordinary body text.

v0.5

Improved

• Reader and font state is tracked safely across object lifetimes.
• Memory patches validate their targets, apply atomically, and recover safely from failures.
• The glyph-hinting safety marker is written atomically and fails closed.
• Superseded-mod removal no longer follows symbolic links.
• Maintainer documentation covers hooks, firmware assumptions, and safety decisions.

v0.4

Added

• Chapters recover when they initially load with the fallback font.
• Config mistakes are reported in the log and enable verbose logging for that boot.

Fixed

• Vertical text no longer overrides the reading font, stops after chapter changes, or shrinks enlarged dictionary text.
• Healthy boots no longer produce verbose log output.

v0.3

Added

• Renamed NickelHintFix to NickelTypeFix.
• Added support for vertical CJK text with optimizeLegibility.
• Added justification fixes for sentence boundaries and punctuation.
• Each fix can attach or sit out independently.
• First boot removes the older NickelHintFix and NickelJustifyFix mods.
• Added before-and-after screenshots and safety documentation.

v0.2

Added

• Releases are built automatically and include KoboRoot.tgz.

Improved

• Updated the documentation.
