v0.0.14

Added

• True (osculating) lunar node: node_type on chart requests ("mean" default, or
  "true"), echoed as the chart's node_type. The node is where the Moon's instantaneous
  geocentric orbit crosses the true ecliptic of date, from the kernel's state vectors;
  it matches Swiss Ephemeris' TRUE_NODE within 1″. Python takes node_type= on chart,
  horary, election and transit; WASM requests take node_type.
• Sripati house system (S): Porphyry's cusps as the middles of the houses, the cusps
  halfway between them.
• Vedic astrology (docs/vedic.md): vedic_calendar (also vedic_calendar on chart
  requests), the panchanga of a moment and place: sunrise, vara, tithi, nakshatra, yoga and
  karana with their start and end, the amanta and purnimanta month with adhika months,
  ritu, ayana, samvatsara and the Shaka and Vikram years; and jyotish (no kernel
  needed), a chart's sidereal placements with nakshatras and vargottama, the twenty vargas
  D1-D60 and the Vimshottari dasha to five levels. Python Engine.vedic_calendar,
  jyotish, vedic_calendar=; WASM engine.vedicCalendar, jyotish.

The true node, Sripati houses, nakshatras and vargas are ported from Priyank Gahtori's
Khagole fork (https://github.com/PriyankGahtori/Khagole).

Changed

• ChartRequest has new public fields (node_type, vedic_calendar), and
  planets_and_sidereal_time takes a NodeType.

v0.0.13

Added

• Minor bodies: Ceres, Pallas, Juno, Vesta, Astraea, Eris, Sedna, Makemake, Orcus and Ixion
  in every chart (after Lilith, before the angles), from embedded tables sampled from JPL
  Horizons for 1849-2151 (within 3″ of it; outside, unavailable_bodies). They form
  aspects within their own orb (default 3°, whatever the orb method) but none with each
  other, and take no part in fixed-star conjunctions or the temperament.
  MINOR_BODIES / is_minor_body are public, and MINOR_BODIES is exported to Python.
• Python: Engine.chinese_calendar(moment), excerpt_kernel(path, start, end),
  election(chinese_calendar=), and every exception carries the API error code in .code.
  WASM: Engine.chineseCalendar(utc) and an Engine.kernels getter.

Changed

• About 3× faster charts from file-backed kernels (cached kernel reads, one nutation per
  chart); outputs are bit-identical.
• time_lords returns Result<TimeLords, EngineError>.

Fixed

• Corrupt or hostile kernels can no longer request huge buffers or overflow addresses;
  kernels whose bodies are split into several time segments use the segment covering the
  date.
• Nonsensical input (latitudes beyond ±90°, non-finite numbers and orbs, impossible dates,
  a quesited house outside 1-12) is rejected as invalid_input instead of computed.
• Election searches confirm each window on exact positions before counting it.

v0.0.12

Added

• Ba Zi: the date option gives the year, month and day pillars of a date (flow: 流年,
  流月, 流日, with the jie that opened the month), from an embedded table of the jie terms of
  1900-2100 (no kernel needed).

v0.0.11

Added

• Zi Wei Dou Shu: the date option casts the horoscope down to the month (流月) and day
  (流日) of a date, read in an embedded lunar calendar for 1900-2100 (no kernel needed).
• 120 charts and 80 horoscopes checked against iztro, the reference implementation of the
  common school.

v0.0.10

Added

• Zi Wei Dou Shu: each palace's minor_stars (the 38 minor stars of the common school),
  gods (the 長生, 博士, 歲前 and 將前 cycles) and flying transformations of its stem;
  the year option adds the horoscope of that year: the decade (or childhood) limit, the
  small limit and the year, each with its palace names, transformations and moving stars,
  and the year's gods.
• Ba Zi: the year option adds the year's pillar (annual), seen from the Day Master.

v0.0.9

Added

• Zi Wei Dou Shu: zi_wei(calendar, birth, longitude, utc_offset_minutes, options) (no
  kernel needed; Python zi_wei, JavaScript ziWei) casts the Purple Star chart from a
  chart's Chinese calendar: life and body palaces, palace stems, the five-element bureau,
  the 14 major stars and 14 auxiliary and malefic stars with their brightness, the natal
  Four Transformations, the life and body masters, and (given the native's sex) the decade
  and small limits. Leap months split at the 15th by default. See docs/chinese.md.

v0.0.8

Added

• Chinese calendar: ChartRequest::chinese_calendar (chinese_calendar in Python and
  JavaScript) adds a chinese_calendar key to a chart: the solar terms from the last 立春
  to the next jie term, the lunar months around the date (leap months by the modern rule,
  including the 2033 case) and the equation of time. Also chinese_calendar(kernels, instant).
• Ba Zi: bazi(calendar, birth, longitude, utc_offset_minutes, options) (no kernel needed;
  Python and JavaScript bazi) casts the Four Pillars on true solar or civil time, with
  either Zi-hour convention: hidden stems, Ten Gods, NaYin, life stages, element balance,
  the lunar date and, given the native's sex, the luck pillars. See docs/chinese.md.

v0.0.7

Added

• Time-lords: time_lords(birth, sun_longitude, ascendant_longitude, start, end) (no kernel
  needed; Python time_lords, JavaScript timeLords) gives the annual profections (age,
  sign, lord of the year, activated house) and the firdaria with their sub-periods, in the
  day or night sequence with the nodes last, after Bonatti.
• chart_dignities(chart, scheme) (no kernel needed; Python chart_dignities, JavaScript
  chartDignities) judges a computed chart's condition, sect and receptions again under the
  Lilly or the Dorothean scheme.

Fixed

• The Python type stubs list dignity_scheme and quesited_house.

v0.0.6

Added

• Essential dignities on every chart. Each of the seven planets carries a condition: its
  domicile, exaltation, triplicity, bound and face (with the lords of its place), detriment,
  fall or peregrine, Lilly's points, its sect and whether it is in sect, above the horizon,
  cazimi, combust or under the beams, oriental or occidental, and fast, slow or stationary.
  The chart adds its sect, the receptions among the planets, antiscia and
  contra-antiscia, and its planetary_hours (left out of transit skies). Sources and rules:
  docs/dignities.md.
• dignity_scheme request option: lilly (default; Lilly's triplicities and Ptolemaic
  terms) or dorothean (three triplicity lords and the Egyptian bounds).
• Horary judgment. calculate_horary_chart takes the quesited house (Python
  quesited_house=, JavaScript quesited_house) and adds horary_data.judgment: the
  significators of the querent and of the quesited, the aspect they perfect within their
  signs, the Moon's aspect to the quesited's lord, prohibition, refranation (a station found
  in the ephemeris), translation and collection of light, and the receptions between the
  significators.
• Considerations before judgment: the Moon in the via combusta (MOON_VIA_COMBUSTA), in
  the last degrees of her sign (MOON_LATE_DEGREES), and the lord of the Ascendant combust
  (ASC_RULER_COMBUST).

Changed

• ChartRequest has a dignity_scheme field, and calculate_horary_chart a third argument
  (quesited_house).
• The demo site has a dignity scheme selector and a dignity column.

v0.0.5

Added

• Degree qualities after William Lilly (Christian Astrology, 1659, p. 116):
  degree_qualities gives the masculine or feminine, light, dark, smoky or void, pitted,
  lame (azimene) and fortune-increasing qualities of a longitude's degree, and
  degree_quality_table returns the whole table. Python: degree_qualities /
  degree_quality_table. JavaScript: degreeQualities / degreeQualityTable.
• Elections weigh the degree qualities of the Moon and the Ascendant: MOON_PITTED_DEGREE,
  MOON_AZIMENE_DEGREE, MOON_FORTUNE_DEGREE, ASC_PITTED_DEGREE, ASC_AZIMENE_DEGREE,
  ASC_FORTUNE_DEGREE, ASC_LIGHT_DEGREE and ASC_DARK_DEGREE. Scores change for moments
  where they apply.
