-Mongoose and mongodb dependencies have been updated to the most recent versions in package.json
-Updated the project for use with the newest mongoose major version which required fixing many breaking changes to a number of files in the explorer
-Removed the db.find_address_tx() function as it is unused
NOTE: This update requires mongoose 6.0.10 or higher. If you are getting errors running the explorer after upgrading, it is recommended to run an 'npm update' or manually update mongoose to a more modern version which should fix the problem
-Suppress the "DeprecationWarning: Mongoose: the `strictQuery` option will be switched back to `false` by default in Mongoose 7" warning msg when starting the explorer and using any of the scripts that connect to mongo
-The SIGINT and SIGTERM signals are now being caught and handled in the sync.js file so that most options for syncing blocks, markets, peers, masternodes, etc. are now being gracefully shut down instead of killed in the middle of the process. This should help prevent data anomalies when you need to stop or kill a sync process
-The update_tx_db function was moved from the database.js file into the sync.js file so that block syncs can now be gracefully stopped. The update_tx_db function was also copied to the benchmark.js
-The save_tx function was moved into the module.exports for the database.js file so that it can now be called from outside the database.js file
-Added locks to all sync processes (blocks, markets, peers, masternodes) as well as "create backup", "restore backup" and "delete database" functions. This helps prevent problems with syncing data while a backup is in progress for example
-The code to initialize certain database collections on startup was moved into database.js and is now called from restore_backup.js and delete_database.js. This effectively allows the database to be deleted or restored to a completely different backup while the explorer is still running
-Lock functions (create_lock, remove_lock, is_locked) were moved into explorer.js for better reusability and rewriten to be synchronous
-is_locked function now accepts an array of lock files to be able to check for multiple locks in a single call
-remove_sync_message() function was moved into database.js so that restore_backup.js and delete_database.js can also check for and remove the sync msg if it exists
-Useful Scripts section updated in the README to make it clear that the explorer no longer needs to be stopped for these scripts to be run
-Most if not all log messages now start with a capitlal letter
-All node dependencies are up-to-date in package.json
-Updated semantic versioning of some node dependencies in package.json
-Applied fixes to necessary explorer files to fix breaking changes to mongoose dependency
-Update README with new Node.js and MongoDB version recommendations
NOTE: Node.js must be updated to at least v14.13.1 to fix breaking errors in a few of the updated dependencies
-Also add output displaying which block is currently being checked as before it was almost impossible to determine what, if anything was happening in check mode
-Replace tabs with double-spaces
-Betting spacing and lining up of code functions
-Add missing semi-colons
-Remove extra characters and spaces where applicable
-Remove commented-out code fragments
-Add missing 2021 date to LICENSE
-Small touchups and other misc nitpickings
-Restructured the settings.json.template and settings.js files with better groupings
-Added better comments for improved explanations of all settings
-Better handling of page length options on all datatables; Page length options are now configurable and also only display options based on limits set by certain items_per_page and max_items_per_query settings
-Markets have been extended to support unlimited trading pairs for each exchange
-Added coin_symbol and pair_symbol to the markets schema to support multiple trading pairs
-Added a burned field to the richlist schema for tracking burned coin addresses
-Added a locale string for the new richlist wealth distribution "Top 1-100 Total" table row
-Updated a couple locale strings that were incomplete or needed fixing (api_getblockhash and api_getnextrewardwhenstr)
-Added a new css class to remove some redundant inline styles for the richlist wealth distribution color boxes
-Richlist page now allows better separation of the top list(s) and the wealth distribution table and chart (you can now hide or show sections as desired)
-Richlist page now allows for better burned coin support (Hide burned coin addresses from lists and totals even when the burned coin amounts are still included in the total coin supply value)
-Block page now only displays the raw block link if the api_page.public_apis.rpc.getblock.enabled settings is set to true
-Transaction page now only displays the raw tx link if the api_page.public_apis.rpc.getrawtransaction.enabled setting is set to true
-Rate limiting class has been made global and is now used to limit market requests
-getnetworkhashps rpc call now returns a '-' if shared_pages.show_hashrate is not set to true
-Searching for unsycned blocks/txs no longer saves the data locally but instead still shows the data on screen. This helps prevent syncing data out-of-order (This eliminates the need for db_index.pid which has been removed)
-Coin supply is now always taken from the stats collection database instead of from the wallet via rpc command in all cases except when syncing
-Lots of misc fixes and code cleanup changes
