1 0.9.0
═══════

1.1 Breaking changes
────────────────────

  ⁃ *Dropped emacsql dependency*: gnosis now uses Emacs's built-in
    `sqlite' module (requires Emacs 29+).  The new `gnosis-sqlite'
    backend handles all database access.
  ⁃ *Unified database*: org-gnosis has been merged into gnosis.  A
    single `gnosis.db' stores both themata and nodes.  Existing
    org-gnosis data is migrated automatically.
  ⁃ *Decks removed*: the deck abstraction is gone.  Existing deck names
    are automatically converted into tags during the v6 migration, so no
    data is lost.  Export and import are now thema-centric with tag
    filtering.


1.2 New features
────────────────

  ⁃ *Anki import*: import Anki decks or user collections directly with
    `gnosis-anki-import'.
  ⁃ *Tag filtering*: `gnosis-tags-filter-prompt' supports `+tag -tag'
    syntax for include/exclude filtering.  Used in export and
    `gnosis-collect-thema-ids'.
  ⁃ *Day start hour*: `gnosis-algorithm-day-start-hour' (default 3) lets
    you define when a new review day begins.
  ⁃ *Tag bulk operations*: rename, regex bulk rename (`R'), merge case
    duplicates (`C'), bulk delete, and suspend/unsuspend from the
    dashboard tags view.  Tag renames are merge-safe (handles UNIQUE
    conflicts when target tag already exists).
  ⁃ *Elapsed time intervals*: the algorithm uses actual elapsed time for
    interval calculation.
  ⁃ *Review transient menu*: `gnosis-review' uses transient instead of
    completing-read.
  ⁃ *Template expansion*: `{*}' heading markers in templates are
    expanded relative to insertion context via
    `gnosis-org-expand-headings'.
  ⁃ *Export with tag filtering*: `gnosis-export-themata' supports tag
    filtering and node export.


1.3 Dashboard
─────────────

  ⁃ Tags view with regex filter (`l'), regex search (`SPC'), and tag
    counts.
  ⁃ Bulk tag rename via regex pattern (`R') using a temp-table approach
    for O(1) SQL statements regardless of batch size.
  ⁃ Anki import keybinding in the dashboard menu.
  ⁃ Merge case-duplicate tags (`C'): groups tags by case, keeps the
    most-used variant as canonical.
    ⁃ Meant to simplify imports from anki decks hierarchical tag
      structure
  ⁃ Entry cache for themata view (avoids re-querying unchanged entries).
  ⁃ Cache invalidation on tag mutations so the themata view stays fresh.


1.4 Performance
───────────────

  ⁃ *Batch SQL helpers*: `gnosis-sqlite-execute-batch' and
    `gnosis-sqlite-select-batch' auto-chunk IN clauses to stay within
    `SQLITE_MAX_VARIABLE_NUMBER'.
  ⁃ N+1 query patterns eliminated throughout: tag suspend, tag delete,
    bulk link, export, and dashboard operations.
  ⁃ Bulk tag rename uses a temp mapping table (4 SQL statements for any
    number of renames, instead of 2N).
  ⁃ `SELECT DISTINCT' replaces Elisp deduplication for tag lookups.


1.5 Bug fixes
─────────────

  ⁃ Fix DST bug in `gnosis-algorithm-date'.
  ⁃ Fix `gnosis-review-topic': flatten select results, fix y-or-n-p
    logic.
  ⁃ Fix `gnosis-completing-read' to use `completing-read' for
    require-match.
  ⁃ Fix force-sync purge and journal link FK violation.
  ⁃ Warn on duplicate filename when timestring is nil in node creation.


2 0.8.0
═══════

2.1 New features
────────────────

  ⁃ Auto input-method detection: gnosis detects the script of the
    expected answer (Greek, Cyrillic, etc.) and activates the
    appropriate input method during review.  Configured via
    `gnosis-script-input-method-alist'.
  ⁃ Change thema type and deck via `gnosis-update-thema'.
  ⁃ Dashboard bulk-link action for currently displayed themata.
  ⁃ Dashboard header-line with entry count and context.
  ⁃ Asynchronous deck import with `gnosis-import-deck-async'.
  ⁃ Demo deck included in `decks/demo.org'.


2.2 Performance
───────────────

  ⁃ New `gnosis-tl' module replaces `tabulated-list-print' for dashboard
    rendering (3-4x faster).
  ⁃ Progressive async rendering for large dashboards.
  ⁃ Batch-fetch review data instead of per-thema queries.


2.3 Bug fixes
─────────────

  ⁃ Fix anagnosis event calculation in the algorithm.
