Following are the main changes which have been made for v3 of Solar Fire. A number of smaller changes have also been made, but have been excluded from this list for the sake of brevity.

Context Sensitive Help: Help may be invoked by using the F1 key anywhere in Solar Fire.

New Chart Points: 8 TransNeptunians, TransPluto, Black Moon Lilith (mean)

New Chart Types: Tertiary, Minor and User Rate Progressed; Ascendant Arc and Vertex Arc and User Arc Directed; Coalescent; Prenatal (18 types, including conception and quickening); Rising/Setting using either visual or true altitude; Transiting and Progressed Lunar Phases.

Savable Charts: Return, Ingress, Prenatal and Relationship charts may also now be saved to a chart file.

Retainable Charts: Any selection of calculated charts may be retained for an indefinite number of future Solar Fire sessions. Retained charts appear immediately in the list of "Calculated Charts" when Solar Fire starts up. Any type of chart may be retained, including composite and progressed charts, for example.

Opening Charts: It is possible to search for a chart through all your chart files at once. Chart names may be displayed in a variety of orders to help find the charts you want. Charts may be opened from Nova type chart files transparently.

Chart Comments: Virtually unlimited comments or text may be added to any saved chart, and this text may be easily browsed or edited whilst opening the chart.

Deleting Charts: Any number of calculated charts may be selected for deletion all at once.

Rectifying Charts: The date of a chart may now be altered in addition to the time and the Midheaven. This makes it possible to cross date boundaries when attempting to rectify charts whose times are close to midnight.

Displayed Points: It is now possible to select a set of displayed points to apply to a single chart instead of to all charts. This makes it possible, for example, to view only the outer planets in a transits chart outside all the planets in a natal chart.

DTP: Any chart or grid displayed in Solar Fire may now optionally be copied to the clipboard or to a file in Windows Metafile format. This allows scalable Desk-Top-Publishing quality charts to be viewed and printed in many other programs.

Draconic Zodiac: The Draconic zodiac may be selected for the calculation of any new chart, in addition to the existing zodiac types. Draconic charts may be mixed with other types of charts in biwheels and reports, for example.

Angle Progression Methods: Solar arc in longitude and right ascension; Naibod in longitude and right ascension, mean quotidian (also known as daily houses). These may be used both in progressed charts and in dynamic progressions.

Progressions Day Type: May be either Standard or Bija

Lunar Parallax: The moon’s position may optionally be adjusted to take account of the location on the earth’s surface. This correction may be used in any chart or dynamic report.

Vulcan Calculation: The position of Vulcan may be calculated using either the orbital parameters proposed by L.H.Weston, or the theory of D.Baker.

Dials: Any displayed wheel may easily be viewed as a 90 degree dial. The wheel designer may be used to design dials of any modulus for viewing in Solar Fire.

Wheel Designer: All of the supplied wheel and dial display styles are editable with a supplied utility program. You can also create your own designs from scratch if you prefer. Editable features include zodiac glyph style, house cusp style and arrows, color fills, planet and degree positions, and much more.

New Dynamic Reports Features: Dynamic reports may use any progression or direction method. From a dynamic report you can: View interpretations of a dynamic event (e.g. Transiting Uranus Square Natal Sun); Export all the interpretations for the report to a file for editing or printing in a word-processor; View a list of similar events, including the number of exact hits before and after the report; View a list of aspects made to the radix chart by an eclipse or stationary point; View a chart for the time of the dynamic event; View a graphical Time Map for all the items in the report.

New Reports: Horary - planetary day and hour, almutens of houses, ancient dignities, point count per planet; Sensitive points - zodiacal positions at which aspects are made to chart’s planets; Midpoint Modal Sort - zodiacal midpoints sorted by mode; Arabic Parts - zodiacal positions and aspects to chart’s planets; Star Aspects - zodiacal positions and aspects to chart’s planets plus keywords for each star; Star Parans - list of stars in paran to chart’s planets plus keywords for each star; Planetary Nodes - zodiacal positions of each planet’s nodes and aspects to chart’s planets

Planetarium: Any chart may be displayed on the celestial sphere with fixed stars in the background. Special features are: Click on a planet to find the nearest star; Double click on any star to get full information, including an interpretations (where available); View the sphere in equatorial, ecliptical or local coordinates, from the side or towards either pole; Rotate the celestial sphere by clicking on a scroll-bar; Highlight any constellation by selecting it from a list

Time Map: Any dynamic report may be displayed graphically with bar lines indicating entering and leaving orbs along a time scale. This is scrollable and printable to allow all events in the report to be viewed.

Interpretations: Solar Fire is supplied with 2 sets of interpretations - one for natal charts and one for transits to a natal chart. It is also possible to specify a different default interpretations file for up to 7 different types of charts or dynamic events, if you create or acquire other interpretations sets. For example, you can use one set of interpretations for a natal chart, and another set for a solar return chart.

Interpretations Compiler: This now keeps track of all the text files related to a set of interpretations, and allows them to be edited directly from the compiler using Windows Notepad, Windows Write or any other word-processor of your choice.

Fixed Star Editor: Technical data and interpretations text my be entered for any fixed stars or other astronomical objects for use in the planetarium and fixed star reports.

Arabic Parts Editor: Any combinations of A+B-C may be entered for use in the Arabic Parts report.

Ephemeris Generator: It is possible to browse or print an ephemeris for any combination of planets and asteroids for virtually any time period and using any time interval.

Utilities Menu Editor: Any program may be added to the utilities menu so that it may be called up directly from Solar Fire.
