koreader v2026.07 release notes

It's been about four months since the previous release, so it's about time, isn't it? One very interesting addition is background cleanup for PDFs with Mask and SMask, which is technobabble for backgrounds (particularly in Archive.org PDFs, https://github.com/koreader/koreader/pull/15401). It means you might not need preprocessing to be able to open them on your ereader without having to be fairly patient when turning pages, though the usual warnings apply: backgrounds are not just the yellowish color of paper, but they might also contain most of the non-textual content, if any.

Kobo v5 support was finally merged (https://github.com/koreader/koreader/pull/12401), and will also reach the nightly builds server soon. There's also new or improved support for the PocketBook Era Lite, reMarkable Paper Pure, newer Onyx Android devices, and some Kindle models.

The hotkeys plugin now supports single-key shortcuts (https://github.com/koreader/koreader/pull/14867), and speaking of plugins, there is now built-in support to delete them (https://github.com/koreader/koreader/pull/15240).

SyncService is replaced by the new Cloud storage plugin (https://github.com/koreader/koreader/pull/15210). It supports uploading, downloading, and deleting selected files, configurable servers and upload folders, natural sorting, and improved WebDAV handling.

And last but not least, there's now OPDS 2.0 basic support (https://github.com/koreader/koreader/pull/15696).

This month's logo was contributed by @thunder_clud.

We'd like to thank all contributors for their efforts. Some highlights since the previous release include:

  - findText(): return list of ldomXRange instead of ldomWord

  - cre.cpp findText() and findAllText(): Updated to handle returned ldomXRange instead of ldomWord, and added optional searchFlags params.
ReaderTypography: add Malayalam to the list of supported languages.

ReaderSearch: enhanced search on CreDocuments

See https://github.com/koreader/koreader/issues/10366#issuecomment-4642735530 (flags re-ordered since this post - don't trust them there).

I settled on:

2 others commented out would give:
```
    -- For CreDocuments, different search features are available:
    -- Enhanced search flags:
    --   MATCH_ACROSS_TEXT_NODES     = 0x0001
    --   COLLAPSE_CONSECUTIVE_SPACES = 0x0002
    --   NORMALIZE_CANONICAL         = 0x0004
    --   NORMALIZE_COMPATIBILITY     = 0x0008
    --   IGNORE_FORMAT_CONTROL_CHARS = 0x0010
    --   FOLD_SPACES                 = 0x0020
    --   FOLD_APOSTROPHES            = 0x0040
    --   FOLD_HYPHENS                = 0x0080
    --   IGNORE_DIACRITICS           = 0x0100
    -- Make a few types of search available as radion buttons
    -- (These are available to be updated/extended by user-patches)
    search_types = {
        -- Title of the radio button , search_flags, use_regex
        { _("Ignore accents / stress marks"), 0x01FF, false },
        -- { _("As typed"), 0x0017, false },
        -- { _("Legacy search"), 0x0000, false },
        { _("Regular expression (long-press for help)"), 0x0001, true },
    },
    default_search_type = { "", 0x00FF, false }, -- Most except IGNORE_DIACRITICS
```
These Radio buttons (each setting a set of flags) are mutually exclusive, but they can also be all unchecked (in which case, we use the defaults we seem to have all agreed on). Case insensitive is an independant one that works with all others (and the default of none). Should they be squared checkboxes ?
