Arduino full changelog

HOTFIX:
Fixed regression in library discovery (failing to compile bundled libs, like SD or Ethernet, on some platforms)

Ide:
Fix status bar custom board preferences disappearing (thanks @magedrifaat)
Boards Manager bugfix: sometimes the "Install" button appeared instead of "Update" after entering a search term.
Libraries/Boards Manager: the Type and Category filters are kept after install/uninstall.
Added 'deprecated' label support in Boards Manager, platforms marked as deprecated are shown at the bottom of the list.
Serial Plotter: line endings dropdown menu now comply with the global preference settings. (thanks @sceniclife)
Libraries Manager: Maintainer is displayed instead of the Author.
Firmware Updater: Added new firmwares and support for Nano RP2040 Connect.
Boards Manager: cached 3rd party package_index.json are no more deleted if the origin URL is removed from preferences, this allows other tools (like arduino-cli), that may have different URLs configuration, to work properly.
The board configuration submenus are now scrollable.

[ide]:
Reverted the bundled Java JRE to the latest freely redistributable Oracle JRE for all
platforms except:
macOS (due to notarization)
aarch64 (due to missing graphical support)
Switching to AdoptJDK demonstrated to be more challenging than expected, bringing in
some corner case bugs that were not being caught by our testing procedures:
https://github.com/arduino/Arduino/labels/OpenJDK
To guarantee the best user experience we decided to revert to the latest working JRE
until all the issues are resolved.
Improved visualization of compiler errors (@matthijskooijman)
Fixed: "Comparison method violates its original contract" error in library manager
Serial monitor is no more cleared during upload, so it can be copy/pasted (@PaulStoffregen)
[arduino-builder]:
FIX REGRESSION: library priority selection for bundled libraries (like SD or Ethernet)
FIX REGRESSION: use AVR core installed via Board Manager (when present) instead of the one bundled in the IDE

[ide]:
FIX: Serial plotter do not hang if empty lines are received
A lot of accessibility improvements in Libs and Board managers GUI for screen readers (thanks @joew46167)
Sligtly improved support for themes in Libs and Board managers (thanks @matthijskooijman)

IDE:
Live font resize now applies to console and serial monitor too @Pieter12345
Make it easier to build the IDE from sources on Windows @Pieter12345
Smaller Preference window, suitable for supersmall screens

IDE:
New target! ARM64 boards are now fully supported (Nvidia Jetson and RaspberryPi3 with 64bit operating system)
Fix UTF8 related bugs on Windows
Fixed: can now compile again using OpenJDK (removed dependency on JavaFx)
Fixed: only use touchBar on OSX 10.12 or higher
PluggableDiscovery: easily add your own discoverer and make it available in Boards/Port menu (thanks @PaulStoffregen for the idea and the initial implementation)
LibManager: reduce slowdown when searching
Fixed: ensure a sketch line is visible when it contains an error and must be highlighted
Linux: the installer now tries to install a symlink is /usr/local/bin (this doesn't affect usual non-systemwide installation) Thanks @2E0PGS
Wifi-updater:
Fix firmware upgrade not being available for 3rd party WINC boards
Arduino-builder:
Use lexicographic distance as last chance to spot the right library (if every other tecnique failed)
Fix some prototypes being inserted in the middle of a function

[ide]:
Fixed: command line parsing of version parameters when installing cores/libraries
Platform indexes are now downloaded using https
Fixed: on some newer linux distrubitions, NPE when loading GTK look-and-feel without libgtk2 installed

[ide]:
Fixed IDE doesn't start if library_index.json is corruped.
Fixed IDE doesn't start if a library with invalid version is found.
Fixed Rare build errors in very complex sketches (like Marlin firmware).

Added workaround for menu visualization bug in MacOSX 10.13 beta. Thanks @puybaret
Fixed bug for negative-font-size.
New/Rename tabs now allows names starting with a number.
