Here is a list of the changes included in each new version of our programs.  Big Deal Items (Major Releases only) are shown in Red Font.

Fun Fact: we have 4 different kinds of releases: 

• Major Releases: 
  • The second number changes (PAT 2.10.0)
  • You should upgrade immediately because we either found a nasty bug or put in an awesome new feature.
• Minor Releases:
  • The third number changes (PAT 2.10.1)
  • You should upgrade, but its not urgent.  We added something of little importance somewhere in the program.
• Test Releases:
  • The fourth number will change (PAT 2.10.2.1)
  • We only send these to individual users for testing purposes. 
• Earth Shattering Releases:
  • The first number will change (PAT 3.0.0)
  • Reserved for a change so big we'll probably need a music video with a marching band to properly communicate how big of a deal this change is.  ​

• In the LMP Point-to-point Tab, now (i) you can select None in the Sink dropdown and get stats and gen weighted analysis on a single point, (ii) sorting by date sorts by date, not alphabetically, and (iii) a filter was added so that instead of automatically showing all companies, it shows the ones you've selected on the Data View Tab.  These new features added after a few back and forths, but ultimately took 24 days. 

APC Reporter 1.23.6 (April 13, 2022)

• Bug Fix: When you want to share a PROMOD run with us, you read a case into APC Reporter and press the Upload Button.  We automatically populate a list of PROMOD files, and now that list includes the PFF file.  Kind of an important one! 
• Bug Fix: Have you ever looked at the details for a single hour?  Probably not, but if you did, maybe you realized that it always said "Gathering Details for Hour...".  Even long after the details were gathered.  Now the label disappears when the details have been gathered, as desired.

APC Reporter 1.22.14 (September 8, 2021)

• Bug fix: In Batch Mode only, within pool cost in the MISO APC calculation was using gen weighted LMP when it shouldn't have been.  Issue resolved in 5 days. 

​

• Unit Hourly Month View: Now you can pick a month and see that unit's data in tabular or graph form.  Now the Unit Hourly graphs might actually be useful?  This new feature was added in 3 business days.

APC Reporter 1.22.9 (July 19, 2021)

• The default view on the Data View tab is set to the entire year, not just January.  Since we started pre-loading Data View in version 1.22.6, it no longer makes sense to view January only by default.  Responded in 26 (weekend) hours.

APC Reporter 1.22.8 (July 16, 2021)

• Renewable Summary values will now update when switching between On/Off-peak and 'Round The Clock (RTC). 

APC Reporter 1.22.7 (July 13, 2021)

• We replaced the FTP!  Now you can use the new Upload Button to share files with us. Check out the Training Video.

APC Reporter 1.18.4 (January 28, 2021)

• Bus mapping for multiple TBUS records: If a unit is mapped to 2 buses (60% at one, 40% at another), the LMP reported will be from the majority bus, not the first bus record. 
• Capacity Factor was improperly using MAXCAP (reported zero when unit on outage)

​
APC Reporter 1.18.3 (January 25, 2021)

• Run time speed and Security Improvements.

APC Reporter 1.18.2 (January 22, 2021)

APC Reporter 1.17.2 (January 5, 2021)

APC Reporter 1.17.1 (January 4, 2021)

• Changed how the unit filter works on the Options Page:  Only filters by long unit name.  Use the unit type dropdown added in 1.17.0 to filter by unit type.

• Select units by category on the Options tab. 

APC Reporter 1.16.1 (December 21, 2020)

• Unit Hourly Graph: When you switch from a unit with TRN/UNT data to a unit without data, the graph wouldn't update. Now it goes blank.
• LMP P2P, Units with no Data:  Even if a unit is tracked, it may not have data in the UNT and TRN files to support tracking.  When this happens, we allow the name to appear in dropdown displays, but we now append "(No Data)" to the unit name string. 
• Renewable Summary Dropdown Year: The month/year label was off by +1 year.  We fixed it.
