## Summary
Fixes a bug in the settings menu, where previously wrap-around only
worked when scrolling upwards. Now, scrolling downwards on the last list
element wraps around to the top as expected.
Resolves#236.

## Summary
* **What is the goal of this PR?** (e.g., Fixes a bug in the user
authentication module, Implements the new feature for
file uploading.)
This PR refactors the semantic version comparison logic used during OTA
update checks.
Memory stats before :
RAM: [=== ] 30.8% (used 101068 bytes from 327680 bytes)
Flash: [========= ] 85.7% (used **5617830** bytes from 6553600 bytes)
Memory stats before :
RAM: [=== ] 30.8% (used 101068 bytes from 327680 bytes)
Flash: [========= ] 85.7% (used **5616870** bytes from 6553600 bytes)
* **What changes are included?**
Replaced std::string::substr() and std::stoi() based parsing with a
lightweight, heap-free approach.
Version parsing is now done in a single pass without creating temporary
std::string objects.
Behavior remains identical: versions are still compared as
MAJOR.MINOR.PATCH.
## Additional Context
`std::string::substr() ` creates a new string and performs heap
allocation
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks, specific areas to
focus on).
## Summary
This adds the correctly styled button hints to the keyboard screen as
well as the ability to add hints to the side buttons (and up/down hints
to that screen)

## Summary
* **What is the goal of this PR?** Add EPUB 3 support by implementing
native navigation document (nav.xhtml) parsing with NCX fallback,
addressing issue Fixes: #143.
* **What changes are included?**
- New `TocNavParser` for parsing EPUB 3 HTML5 navigation documents
(`<nav epub:type="toc">`)
- Detection of nav documents via `properties="nav"` attribute in OPF
manifest
- Fallback logic: try EPUB 3 nav first, fall back to NCX (EPUB 2) if
unavailable
- Graceful degradation: books without any TOC now load with a warning
instead of failing
## Additional Context
* The implementation follows the existing streaming XML parser pattern
using Expat to minimize RAM usage on the ESP32-C3
* EPUB 3 books that include both nav.xhtml and toc.ncx will prefer the
nav document (per EPUB 3 spec recommendation)
* No breaking changes - existing EPUB 2 books continue to work as before
* Tested on examples from
https://idpf.github.io/epub3-samples/30/samples.html
## Summary
* **What is the goal of this PR?**
Add a new user setting for paragraph alignment, instead of hard-coding
full justification.
* **What changes are included?**
One new line in the settings screen, with 4 options
(justify/left/center/right). Default is justified since that's what it
was already. I personally only wanted to disable justification and use
"left", but I included the other options for completeness since they
were already supported.
## Additional Context
Tested on my X4 and looks as expected for each alignment.

## Summary
* **What is the goal of this PR?** Fixes a bug -
https://github.com/daveallie/crosspoint-reader/issues/187 - where the
screen would freeze after entering a WiFi password, causing the device
to appear hung.
* **What changes are included?**
- Fixed a race condition in `WifiSelectionActivity::displayTaskLoop()`
that caused rendering of an empty screen when transitioning from the
keyboard subactivity
- Added `vTaskDelay()` when a subactivity is active to prevent CPU
starvation from a tight `continue` loop
- Added a check to skip rendering when in `PASSWORD_ENTRY` state,
allowing the state machine to properly transition to `CONNECTING` before
the display updates
## Additional Context
* **Root cause:** When the keyboard subactivity exited after password
entry, the display task would wake up and attempt to render. However,
the `state` was still `PASSWORD_ENTRY` (before `attemptConnection()`
changed it to `CONNECTING`), and since there was no render case for
`PASSWORD_ENTRY`, the display would show a cleared/empty buffer,
appearing frozen.
* **Performance implications:** The added `vTaskDelay(10)` calls when
subactivity is active or in `PASSWORD_ENTRY` state actually improve
performance by preventing CPU starvation - previously the display task
would spin in a tight loop with `continue` while a subactivity was
present.
* **Testing focus:** Test the full WiFi connection flow:
1. Enter network selection
2. Select a network requiring a password
3. Enter password and press OK
4. Verify "Connecting..." screen appears
5. Verify connection completes and prompts to save password
## Summary
* **What is the goal of this PR?** Fixes#199 - Device falls asleep
during WiFi file transfer after 10 minutes of inactivity, disconnecting
the web server.
* **What changes are included?**
- Add `preventAutoSleep()` virtual method to `Activity` base class
- Modify main loop to reset inactivity timer when `preventAutoSleep()`
returns true
- Override `preventAutoSleep()` in `CrossPointWebServerActivity`
(returns true when web server running)
- Override `preventAutoSleep()` in `OtaUpdateActivity` (returns true
during update check/download)
## Additional Context
* The existing `skipLoopDelay()` method controls loop timing (yield vs
delay) for HTTP responsiveness. The new `preventAutoSleep()` method is
semantically separate - it explicitly signals that an activity should
keep the device awake.
* `CrossPointWebServerActivity` uses both methods: `skipLoopDelay()` for
responsive HTTP handling, `preventAutoSleep()` for staying awake.
* `OtaUpdateActivity` only needs `preventAutoSleep()` since the OTA
library handles HTTP internally.
## Summary
* Replace book and section bin format images with ImHex hexpat
definition
* This should give readers an understanding of the file format but also
supply some utility when validating content/output
## Summary
* Update EpdFontFamily::Style to be u8 instead of u32 (saving 3 bytes
per word)
* Update layout width/height to be u16 from int
* Update page element count to be u16 from u32
* Update text block element count to be u16 from u32
* Bumped section bin version to version 8
## Summary
- Update the button hints on the OTA update screen to reflect the
current front button layout.
- Update user guide to reflect current available settings. A lot has
been added recently!
## Summary
* **What is the goal of this PR?**
Fix file browser failing to navigate into subdirectories with non-ASCII
(Korean/Unicode) folder names.
* **What changes are included?**
- Enable UTF-8 long file names in SdFat (`USE_UTF8_LONG_NAMES=1`)
- Add directory validation before iterating files
- Add `rewindDirectory()` call for stability
## Additional Context
## Summary
* Move home screen battery indicator to avoid clashing with button hints
* Default button mapping was fine, but others clashes with the indicator
## Summary
* Swap from Aleo to Bookerly for wider glyph support
* Swap from Space Grotesk to a small Noto Sans
## Additional Context
* 0.11.0 swapped to Aleo which has a few issues (things like Cyrillic
support for eg)
## Summary
* Redesigned home screen with big option to continue reading and
slightly nicer options to navigate to core sections
* Attempt to use the cached EPUB details (title, author) if they exist,
otherwise fall back to file name
* Adjusted button hints on home screen, removed Back option and changed
left/right to up/down
## Additional Context
* Core of this work comes from @ChandhokTannay in
1d36a86ef1
This parses the guide section in the content.opf for text/start
references and jumps to this on first open of the book.
Currently, this behavior will be repeated in case the reader manually
jumps to Chapter 0 and then re-opens the book. IMO, this is an
acceptable edge case (for which I couldn't see a good fix other than to
drag a "first open" boolean around).

## Summary
* Add setting for line spacing to adjust space between lines
* Aleo is already a bit tighter than Noto Sans and Open Dyslexic, so
have adjusted the values to match, this can be tweaked in the future
## Summary
* Show previous title for unnamed spines
* The spec is a little unclear, but there are plenty of cases where
chapters are split up in parts and should show the previous chapter's
title
* List TOC items instead of spine items in chapter select
* Bump `BOOK_CACHE_VERSION` to `2` to force regeneration of spine item's
TOC indexes
## Summary
* Swap to updated SDCardManager which uses SdFat
* Add exFAT support
* Swap to using FsFile everywhere
* Use newly exposed `SdMan` macro to get to static instance of
SDCardManager
* Move a bunch of FsHelpers up to SDCardManager
## Summary
- **What is the goal of this PR?** Add chapter selection support to the
XTC reader activity, including parsing chapter metadata from XTC files.
- **What changes are included?** Implemented XTC chapter parsing and
exposure in the XTC library, added a chapter selection activity for XTC,
integrated it into XtcReaderActivity, and normalized chapter page
indices by shifting them to 0-based.
## Additional Context
- The reader uses 0-based page indexing (first page = 0), but the XTC
chapter table appears to be 1-based (first page = 1), so chapter
start/end pages are shifted down by 1 during parsing.
## Summary
**What is the goal of this PR?**
Adds a setting to swap the front buttons. The default functionality are:
Back/Confirm/Left/Right. When this setting is enabled they become:
Left/Right/Back/Confirm. This makes it more comfortable to use when
holding in your right hand since your thumb can more easily rest on the
next button. The original firmware has a similar setting.
**What changes are included?**
- Add the new setting.
- Create a mapper to dynamically switch the buttons based on the
setting.
- Use mapper on the various activity screens.
- Update the button hints to reflect the swapped buttons.
## Additional Context
Full disclosure: I used Codex CLI to put this PR together, but did
review it to make sure it makes sense.
