+# ChangeLog
+
+## 2026 (Year to Date)
+
+Coverage: commits from **2026-01-01** through **2026-02-06**.
+
+### Themes
+
+- **Assignment experience + navigation:** continued refinement of assignment navigation (including “readings” integration) and UI polish.
+- **Authoring/build stability:** better build hygiene in `rsptx` tooling (clean logs, cleaned output folders) and dependency work to reduce PreTeXt friction.
+- **Instructor/admin capabilities:** expanded tooling for course administration (token cleanup, CSV enrollment) and billing/invoice-related fixes.
+- **Assignment Builder options:** improved exercise configuration—especially for ActiveCode (CodeLens) and the new/expanded IFrame exercise type.
+
+### Notable changes (grouped)
+
+#### Releases / version bumps
+- Multiple **release/version** bumps (primarily in `projects/interactives/pyproject.toml`).
+
+#### Assignment navigation + readings UX
+- Implemented and iterated on **two-way assignment navigation** (top/bottom navigation, readings integration, styling fixes).
+- Added `readingNames` support and related UI/markup adjustments.
+- Improved assignment navigation behavior and added material icons to assignment pages.
+
+#### Assignment Builder: new capabilities and settings fixes
+- **IFrame exercise type:** added IFrame exercise type/components and later removed an iframe height restriction in preview/input.
+- **ActiveCode improvements:**
+  - Added support for enabling/disabling **CodeLens**.
+  - Tightened up settings/preview plumbing and types.
+- **CodeTailor options:** updated handling to correctly modify `parsonspersonalize` values.
+- Misc. robustness fixes around label toggles (avoid replace/split when `toggleLabels` is null).
+
+#### Peer / Parsons + assessment behavior
+- Parsons improvements including fallback to the problem source when restoring a student answer fails.
+- Multiple changes in the peer/PI area (dashboard + templates + JS), along with ongoing refinements in the peer router.
+- Fixes for MathJax processing and a regression involving counting questions for async.
+
+#### Instructor/Admin operations
+- **API token cleanup:** added ability to delete API token(s) for a course, including a “delete all tokens” capability and supporting UI.
+- **CSV enrollment:** allow a user to be enrolled in a new course by CSV.
+
+#### Billing / invoicing
+- Fixes related to course creation billing flows (invoice checkbox handling) and an additional invoice request fix.
+
+#### Build tooling + dependencies (PreTeXt/author server)
+- Build improvements in `components/rsptx/build_tools/core.py`:
+  - Start builds with a clean log
+  - Clean output folders more reliably
+  - Remove leftover debugging (`set_trace`)
+- `rsmanage build` gained a `--target` option.
+- Dependency work to address **PreTeXt** issues (notably updates in `projects/author_server/poetry.lock` / `pyproject.toml`).
+
+### Month-by-month timeline
+
+#### January 2026
+- Merged/landed the two-way assignment navigation work and related readings UI improvements.
+- Added/expanded Assignment Builder capabilities (CodeTailor options; IFrame exercise type).
+- Improved assignment sorting and decoration of assigned problems.
+- Multiple dependency updates (lxml/pretext/runestone) and several small bug-fix releases.
+- Addressed billing/invoicing edge cases.
+
+#### February 2026 (so far)
+- Instructor tooling: token deletion support (including bulk delete).
+- Authoring/build stability: PreTeXt dependency fixes; cleaner build logs; output folder cleanup; `rsmanage build --target`.
+- Minor version bumps and cleanup.
+
+---
+
+### How to read this repo’s recent work
+Most of the work since Jan 1 clusters into three areas:
+1) **Learner/instructor experience** (assignment nav + builder settings)
+2) **Operational/admin tooling** (billing, enrollment, token hygiene)
+3) **Platform stability** (dependencies + build predictability)
