- *** USE THE INFO FEATURE WITHIN MERLIN FOR THE LATEST DOCUMENTATION ***
-
- 1.7a - New features include:
- * Statistics feature...
-
- * New tracking map - zoomed-in Caribbean area.
-
- * All maps are now chosen from a "pop-up" menu.
-
- -----------------------------------------------------------------------------
-
- 1.6c - Lesser Antilles and some minor islands added to tracking maps.
- Bridgetown Barbados added to "What if..." tracking location menu.
-
- 1.6b - The 12 HOUR PROJECTION OF TREND and N.H.C 12-72 HOUR FORECASTS/OUTLOOKS
- are drawn as a broken line on the tracking maps to differentiate them from the
- solid line of the actual storm track.
-
- 1.6a - New features include:
- * Wind field input added to Alt+[U]pdate, NHC "pop-up" window. Wind
- information that is entered is included in MERLIN Advisory. Registered
- version of MERLIN will also graphically draw the wind field relative to
- the storm's center, on MERLIN's tracking maps.
-
- * Improved handling of the NHC Forecast/Outlook code - partial sets of data
- can now be entered for those times when the NHC supplies partial forecasts
- only.
-
- * N.H.C. 12 (or 24) HOUR FORECAST message replaces MERLIN's 12 HOUR
- PROJECTION message on the MERLIN Advisory "if" NHC information is entered.
-
- * Pacific tracking locations added - Hilo HI, Acapulco MEX, Cabo San Lucas MEX
- and Pto. Vallarta MEX. These locations are "off" MERLIN's tracking maps,
- but text based reports (the MERLIN Advisory and history) still provide
- information if the user desires the ability to track Pacific hurricanes or
- storms.
-
- * Five degrees longitude added to East Coast tracking map.
-
- * No longer have to press "Alt" key to access tracking maps. Also first
- letter of key-to-press for tracking maps added to MERLIN menu.
-
- * The current time zone selection has been added to the Update "pop-up"
- window as a reminder of which time zone you are currently using.
-
- -----------------------------------------------------------------------------
-
- 1.5g - Disable the ability to insert storm readings earlier than the current
- reading which creates a divide by zero error causing MERLIN to crash.
-
- 1.5f - Addition of "loop" feature for business sites that wish to put the
- information provided by MERLIN in an "endless" loop to broadcast across
- television monitors or to display to employees on a dedicated PC at a central
- location.
-
- 1.5e - Minor interface corrections/improvements based on suggestions by
- users.
-
- 1.5d - Reduction of shareware message in upper-left corner to 10% and add
- random city selection to closing shareware screen.
-
- 1.5c - Further tweaking of neural network.
-
- 1.5b - Bug fix to "unDo" feature to correctly revise storm file.
-
- 1.5a - Pre-release of 1993 version of MERLIN. New features for 1993 include:
- * AUTOMATIC UPGRADE capability for all of 1993. Upgrades of the 1.5x series
- will be kept in the IBM Applications Forum on CompuServe. Download any
- 1.5X series that is newer than your registered version and your MERLIN.COM
- file sent with your registration diskette will suppress all SHAREWARE
- messages for any 1.5x series upgrade. The latest version of MERLIN is also
- kept in the Public software Library Catalog, 1-800-242-4PSL.
-
- * A total of FOUR tracking maps, Alt+[A]tlantic, Alt+[E]ast coast, Alt+[G]ulf
- of Mexico and the original MERLIN map accessed by pressing "M" from the
- MERLIN Advisory.
-
- * UNDO mistakes by choosing "unDo" from the MERLIN menu. This eliminates
- editing the ASCII file with a text editor in most situations where in-
- correct information was entered and saved from the Update storm screen.
-
- * SPEED-TRAK, a "speed-up" feature that is used whenever a storm being drawn
- is off-screen.
-
- * National Hurricane Center forecasts can now be plotted on-screen if you
- have access to NHC Marine Advisories. Press Alt+[U]pdate from the MERLIN
- Advisory to bring up the alternate update screen which is where NHC
- forecasts can be entered.
-
- * A Gray color scheme has been added to the program along with new, button
- style, pop-up boxes/menus.
-
- * Neural Net processing dampened for improved performance.
-
- * Support for LaserJet printing by pressing Alt+2 from any of the four tracking
- maps after the map is finished drawing and tracking. Alt+1 is used for
- printing to a dot-matrix printer. MERLIN has support for LPT1 only.
-
- -----------------------------------------------------------------------------
-
- 1.4i - error handling improved when duplicate date/time or duplicate
- latitude/longitudes as previous entry are entered when updating storm.
-
- 1.4h - Bug fix to Update Storm menu item. After updating, it was necessary
- to either re-load the current storm from MERLIN's menu after updating, or
- exit the program and re-start MERLIN to have the correct MERLIN's OUTLOOK.
- 7All other items on the advisory were OK.
-
- 1.4g - Tracking information is presented on-screen while MERLIN is plotting
- the storm's coordinates on the tracking chart. Maintenance upgrade to the
- neural network to include new storm data.
-
- 1.4f - Puerto Rico, Jamaica and smaller islands have been added to the
- tracking chart. A laser jet printed manual is now sent with registration.
- Also, the registered version of MERLIN now has over 100 tracking locations
- included in the menu, and many of these are based on the "official" locations
- normally used by the National Hurricane Center for watch/warning and landfall
- possibility:

-
- 1.4e - A message in the MERLIN Advisory states when the tracking location is
- in the NE quadrant of the storm if the storm is within 100 miles of the
- tracking location. New opening screen based on an image sent to T. M. Parker
- by J. K., a meteorologist and registered user of MERLIN. Minor changes to
- interface.
-
- 1.4d - Review mode allows viewing/printing of previous MERLIN Advisories by
- using the PgUp/PgDn key. 12 Hour Projections now calculated using RatIo
- Tracking Algorithm (RITA). This mathematical model replaces all the
- regression models used by earlier releases of MERLIN. Regression is an
- excellent forecasting tool, but there were rare instances where the data
- presented to MERLIN would cause problems. RITA uses ratios to create the
- 12 Hour Projection, and performs nearly as well as regression when the storm
- is traveling straight. When the storm is turning, RITA significantly
- outperforms regression. Overall, RITA's projection is superior to earlier
- regression models.
-
- 1.4c - Significant improvement to the detail level of the tracking map. Also,
- Five degree longitude increase in tracking map area (ie.more Atlantic Ocean).
-
- 1.4b - All the features of previous versions. Code revisions/optimizations.
- MERLIN now will work with a maximum of 75 readings instead of 50. Credit card
- orders now available thru 1-800 number - see ORDER.FRM file.
-
- 1.4a - All the features of previous versions. Code revisions that prevent
- MERLIN from re-calculating if a menu is popped-down by pressing the Esc key.
- More cities added. Now there are 36 locations instead of 23, and these are
- easily modified by the user with any ASCII text editor.
-
- 1.40 - All the features of previous versions. This is the "official" version
- of MERLIN for the 1992 hurricane season. MERLIN can print the tracking map to
- any IBM/Epson compatible dot-matrix printer. Use ALT+1 (LPT1) or ALT+2 (LPT2).
- MERLIN.DOC is now available on-line, simply by pressing a key from MERLIN's
- menu. Removal of timed shareware delay when exiting program. The purpose of
- the delay was to ensure adequate reading time for closing message. This is now
- just a "press any key" delay. SPANISH LANGUAGE version of MERLIN 1.40 is now
- available.
-
- 1.30 - All the features of previous versions. Graphical tracking capability
- added, based on numerous requests by registered users (EGA/VGA color monitor
- required). Storm intensity color coded. MERLIN's 12 Hour Projection is added
- to the storm track automatically for a visual representation of MERLIN's
- calculated projection of the most recent trend using the mathematical models.
-
- 1.20 - All the features of previous versions. MAJOR upgrade to mathematical
- model. Now, includes curvi-linear regression routines. Previous versions had
- only linear regression for mathematical model. MERLIN automatically chooses
- best method and applies it to forecast based on trend. Free program offer to
- registered users - 4CAST.EXE. This program uses a sub-set of the mathematical
- models in MERLIN to work with ANY data sets.
-
- 1.10 - First major release to public. Uploaded to Compuserve and several
- regional BBS systems (Houston/Miami areas). 1st use of artificial intelligence
- and mathematical models to determine future location/strength of storm based on
- recent trend. Text-based reports and history, viewed on-screen or sent to
- printer.
-
- 1.00 - Early public release to limited user group. Basically the 1.0b version
- after changes implemented, based on Beta team's suggestions.
-
- 1.0b - Beta version, used by Beta team to uncover errors in program
- functionality. This version was not released to public.
