1. Alter method of writing disk sectors to IndexedDB, to avoid dragging along the entire 16KB IO Unit buffer area and unintentionally inflating host disk usage by 30-60X (ouch). This was causing Quota Exceeded errors in recent versions of Firefox.
2. Add onabort traps in B5500DiskUnit to catch QuotaExceeded errors.
3. Modify delay-deviation adjustment mechanism in B5500SetCallback to avoid oscillating between positive and negative cumulative deviations.

6. Reset CPA Algol Glyphs option in default system configuration template.
7. Allow tools/B5500LibMaintDecoder to examine an entire .bcd tape image file instead of just the first 64KB.
8. Add USE SAVEPBT to default options in tools/COLDSTART-XIII deck.
9. Eliminate extraneous "schema update successful" alert when altering a disk subsystem configuration.

4. Implement "Application Cache" support to allow emulator to run off-line in a browser.
5. Implement web-font support and update all UIs to use DejaVu Sans and DejaVu Sans Mono from downloaded .woff or .ttf font files.
6. Rework some code in Processor OPDC, DESC, and indexDescriptor routines, attempting to resolve Flag Bit errors (issue #23). This appears to result in some improvement, but we still see them occasionally under load.

12. Datacom:
- Rework datacom driver keystroke handling for compatibility with Google Chrome.
- Correct typo (line 437) in B5500DatacomUnit reported by Peter Grootswagers (issue #28).
13. Magnetic Tape:
- Implement more granular tape reel animation in B5500MagTapeDrive.
- Open the tape loader window on top of its device window.

15. More intelligently resize peripheral UI controls when their window is resized.
16. Implement lamp test during power-on in B5500Console.
17. Illuminate NOT READY light on Console at power-on if certain minimum configuration requirements are not met.
18. Set all HTML <meta> Content-Type character sets to UTF-8 (were ISO-8859-1); correct problem with FireFox requiring the character set to be specified within the first 1024 characters of an HTML file.
19. Clean up and refactor CSS style sheets
