| 127 | Version 6.2 puts cctv and cms and vds in separate data layers. |

| 128 | Version 6.1 Puts cms messages in json formatted file. Polls for updates. |
|---|
| 129 | Version 6.0 Adds speed-dependent images to infowindow for cctv icons |
|---|
| 130 | Version 5.8 Adds an infowindow with a static image for all cctv icons |
|---|
| 131 | Version 5.7 integrates CCTV icons and button (but empty click handler) |
|---|
| 132 | Version 5.6 integrates CMS features |

| 133 | Version 5.5 renames title to CPTMS, loads static data on startup and dynamic data |
|---|
| 134 | every ten seconds. |
|---|
| 135 | Version 5.4 adds Search box and Center button |
|---|
| 136 | Version 5.3 fixed dot color update defect, increased refresh rate to 10 sec. |
|---|
| 137 | Version 5.2 places red dots overlapping yellow dots. |
|---|
| 138 | Version 5.1 removes the map and street view buttons and the H3 tag. |
|---|
| 139 | Version 5 uses precomputed perpendicular vector in dot adjustment function |
|---|
| 140 | Version 4 Adjust the spacing between dots when the map is zoomed. |
|---|
| 141 | Version 3 does loadGeoJson only once, and subsequently does an ajax load |
|---|
| 142 | of the highways file, and selectively updates only those placePins whose |
