UPGRADE

NOTE: As of v1.100.0-bae4d50, it is no longer necessary to manually restart the explorer after updating, as long as you are using the built-in update script `npm run update-explorer`. All other manual updates such as `git pull` will still require a restart to the explorer after updating.

1.102.0 [June 14, 2023]
-Added better support for NODE_ENV
-Added a new setting to redirect http to https
-Removed the "Full Setup Guide" section from the README

-Updated the README with a new entry to the "Known Issues" section that better explains the padLevels warning msgs when using the forever module
-Updated the README with alternate instructions to the "Manually Link TLS/SSL Certificates to the Explorer" section which better explain which method should be used depending on whether the explorer is running on port 80 for http traffic or not
-Added an rpc cmd queue
-Fixed an issue that caused 2 or more masternodes created in the same transaction to be treated as the same entry
-The "Powered By" footer text is now configurable

-Added support for the Txbit exchange
-Better handling of stop/kill sync processes (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)
-Added support for vin/vout hashes inside an array

1.101.0 [July 09, 2022]

-Network addnode table data no longer wraps onto multiple lines when the data cannot fit on the screen
-Fixed a bug which caused the error page to not show a proper page title
-Fixed a bug which caused the locking mechanism to fail on non-windows computers when the explorer is installed to a directory that has a space character somewhere in the absolute path
-The update_explorer.js script has been improved with better spacing and the ability to restart the explorer automatically to ensure new changes take effect immidiately (works with npm start, pm2 and forever)
-The code to compile scss to css has been moved from the prestart script into its own compile_css.js script which is now called from the update-explorer.js script to apply css changes after update
-The cluster code now handles a custom restart msg which is used to restart the explorer from the update explorer process
-Pm2 and Forever are now referenced by the name 'explorer' instead of ./bin/instance or ./bin/cluster
-Added reload/restart scripts to the package.json for pm2 and forever
-Pm2 and forever now write a pid file to the tmp directory when started. NOTE: Forever is now started from the prestart script due to a bug in forever that prevents the pid from being written to a different directory without the absolute path
-Fixed a bug which caused the prestart script to be run twice when starting the explorer with `npm start`
-The cluster code now accepts a numeric argument to force a specific number of instances to be loaded

-Improved loading speed of the network page by combining 3 separate database calls into 1
-Added support for the Dex-Trade exchange
-Added support for the FreiExchange/FreiXLite exchange (this exchange has 2 separate sites using the same api, so new functionality was added to the explorer to handle alt markets like this with an alt market name, alt logo, market url and an "isAlt" function to determine if the alt name/logo should be used)
-Support was added for the getblockchaininfo rpc cmd which now allows the coin supply to be populated via this function
-The network difficulty chart now supports 2 datasets: POW and POS
-Fixed a bug with the network difficulty chart where it would fail to populate if the shared_pages.difficulty setting was 'Hybrid'
-NetworkHistory.difficulty field was renamed to difficulty_pow and a new difficulty_pos field was added

-Both dependencies and dev dependencies sections have been sorted alphabetically to help prevent auto package.json changes
-The custom user-agent strings for http requests have all been removed
-Fixed an issue with the crex24 market chart that could cause it to be overpopulated with data and therefore unreadable/unusable

1.100.0 [May 29, 2022]
-Added a custom.scss file that can be used to add custom css changes without affecting the ability to do a git pull update
-Added new update script to A) grab the latest code form github, B) update all dependencies, and C) run the database initialize function to ensure new changes take effect immidiately
-freegeoip.app now requires an api key so the peer sync has been updated to use reallyfreegeoip.org instead
-Added extra error checking to the peer sync so that it will error out when the geolocation service does not return a proper object
-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

-Rewrote a number of internal scripts to allow for better cross-platform support (Windown, MacOS, Linux)
-Backup and Restore scripts now use mongo's own encryption instead of tar.gz by default. Older tar.gz backups can still be restored as long as the tar.gz suffix is explicitly added

-Added a link to exchange on markets page
-Added the current git commit id to end of explorer version

-update_heavy has been moved into a proper callback function which is now only called for index and reindex syncs right near the end of the process instead of at the beginning
-Added some tweaks and improvements to the Reindex sync feature (Added an "Are you sure" prompt before starting the reindex, All necessary coin stat data is cleared before starting, More and better messages about what is being done during the process, Shifted some of the code around to be run in a better order)
-Added unique page titles for each individual page
-Added code to prevent caching of local css files
-Bootstrap was upgraded to latest version (v5.1.3) which required tons of changes to the UI. Many little UI problems have been resolved

-Fixed issues loading site in safari browser (Safari behaves differently than other browsers and seems to require the url prefix to be present when loading external libraries to prevent CORS errors)
-Many blockchains allow you to use addnodes without a port # and it will assume the default port internally, but the explorer was failing to parse these peers because it was expecting a port. This is now fixed and will display the peer data without a port in these cases
-Added support for newer (deterministic) Dash masternode format
-More graceful shutdown of node cluster on 'npm stop' with better cleanup of resources on exit
-Added new stop_explorer.sh script which looks up the explorer port # via settings file and closes the application running on that port # instead of saving and killing the process by pid as it did before
-Added support for pm2 and forever using 'npm run start-pm2' and 'npm run start-forever' respectively
-pm2 is automatically installed when starting with 'npm run start-pm2' if it is not already installed
-forever is automatically installed when starting with 'npm run start-forever' if it is not already installed

-Added an api page setting to hide/show logo
-All pages (including the reward and error pages) were updated to include options for displaying a configurable page header with title, image, description and in some cases a last updated date
-The error page was restructured slightly to display a different description based on the type of error (page not found error vs problem loading page error)
-Added new setting options to the `shared_pages` setting for `page_title_image` which allows changing the page title image displayed on applicable pages and also determines whether it uses a flip/spin animation or not
-Added a collection of new `page_header` settings to all pages that control displaying the new page title + image + description and also moved the last updated date from applicable pages into this section as well
-Existing `show_last_updated` settings that were moved a level deeper into the `page_header` have been automatically mapped to the new setting location upon statup to help older installs to work better out-of-the-box
-Locale strings now support replacement text such as {1} and {2} that get automatically replaced with proper values when loaded to allow for locale strings that support dynamic text
-Fixed an issue with too much empty space in the page header (especially in mobile and tablet modes) when `show_panels` was set to false on any page
-Removed unused css class 'loading'
