CML Lab Builder 3.2.0

Downloads

• Already on 3.0.0 or 3.1.0: the app offers this update by itself (small patch, cml-lab-builder-patch-3.2.0.zip, sha256-checked against SHA256SUMS.txt).
• New install: CMLLabBuilder-3.2.0-windows-x64.zip, CMLLabBuilder-3.2.0-linux-x64.tar.gz, or sudo apt install ./cml-lab-builder_3.2.0_amd64.deb.
• ENCOR Lab Builder 1.7 - 2.1: the app shows "full download"; the ENCORLab-* / encorlab_* files are the same builds under the old names.

Library sorted by topic. A patch for 3.0.0 and 3.1.0 (same runtime 2): they offer it by themselves and install it
with Install update. ENCOR Lab Builder 1.7 - 2.1 still get the full download banner.

Added

• Topic tags for every library lab and course, from one controlled list (cmllab/topics.py): OSPF, EIGRP, BGP,
  Redistribution & PBR, VLAN / STP / EtherChannel, HSRP / FHRP, IP services (NAT, NTP), Multicast, VRF, GRE / IPsec,
  MPLS, EVPN / VXLAN, Data center, Security, QoS, Monitoring & assurance, Automation, Troubleshooting, Other, plus
  Walkthrough / Challenge and the track (ENCOR). The library labs get theirs in labsrc/library.yaml (topics:;
  build_library.py refuses unknown topics and labs without any), and both library/index.json and
  labs/index.json carry them. Courses get the most common topics of their labs. Labs from an index without topics
  (other libraries) get derived ones: ENCOR blueprint items, keywords in the id, title, domain and description, and
  node types (nxosv9000 = Data center). /api/library also returns the topic list (topics).
• New library layout: a row of topic chips with counts (multi-select: any of the topics picked in one area, all
  of the areas), labs grouped under collapsible topic headings (Expand all / Collapse all) or one flat list
  (Grouped by topic / List), and compact cards instead of the table: title, Walkthrough / Challenge, difficulty,
  node count, RAM with the red RAM heavy tag, starter / installed / update status, and topic chips that filter
  when clicked. Works in light and dark mode and on narrow windows (one column).
• Search knows the topics: the 3.1.0 fuzzy search also matches topic names (monitoring, data center, gre ipsec), and search, topics and the other filters combine. Still client-side and about 1 ms per keystroke for
  300 labs.
• The library remembers the view, the selected topics and the collapsed groups (browser localStorage).
• Keyboard and screen readers: chips are toggle buttons (aria-pressed, arrow keys move between them), the topic
  headings are buttons with aria-expanded, and the chip row and the lists are labelled.

Compatibility

• The lab packs are unchanged (the topics are only in the index, the lab format rejects unknown fields), so no lab
  versions changed and no Update available shows up. Apps 2.0 - 3.1 ignore the new index field (checked with the
  2.0.0, 2.1.0, 3.0.0 and 3.1.0 builds: they load the new index and install from it), and 1.7 - 1.9 parse it too.
