I've rereleased v3.4-beta-1 with a fix handing a problem with some libraries were incorrectly 'shaded' into the JAR without being properly rebased. In most cases, this does not matter, but it is possible for it to result in conflicts with other mods or plugins that have made the same sort of mistake OR with libraries added externally. No other changes included, so see v3.4-beta-1 for other content.

This is a first drop for including support for Spigot 1.17. It is lightly tested, and is nor likely to be of interest to folks running 1.16.5 or earlier, at this point, though it should work.

Most, but not all, new 1.17 blocks have been added - beta-2 is expected to include the remaining blocks.

Happy New Year!!

This is an important release, in that it is addressing an important security issue for people using SQL for map storage
Specifically, it is relevant if:

• You use PostgresSQL, MariaDB, or MySQL for your map storage, AND
• You use the internal web server (or a proxy leveraging the internal web server) to serve the maps (versus an external web server with PHP)

If this is the case, it is very important to do the following:

• Update to this release (or later)
• Consider updating the password you are using for dynmap to access you database, as it may have been exposed.

If your database server follows 'best practices' (no public internet access, whitelisted to only the IP of your server), this may be less a concern, but I'd still suggest updating the password after you've applied the update, particularly if the password is used for any other purposes.

On more positive notes, this release also includes:

• Fabric 1.16.4 support (thanks to LolHens!)
• Improved error reporting for server misconfiguration (thanks to 811Alex!)
• A fix for image file name updates relative to webp (thanks to thrimbor!)
• Another webp related fix for an exception when PATH is undefined (thanks to silverwolfg11!)
• Improved 1.16 biome support (thanks to KovuTheHusky!)

- Support for Spigot/Paper 1.16.4 (thanks to DeGup!)
- Added support for WEBP image format
- Fix jQuery update

- Include 1.16.3 support
- Fix marker updates to undefined marker sets
- Split JSON to help with some browser parsing issues
- Fix podzol shading
- jQuery update

- Fix rendering of chests (1.16+)
- Fix for legend icons with non-default world names (not 'world')

The features of this release include:

- Fix piston and sticky piston rendering

- Fix stone slab texture on 1.13.2+

- Handle malformed skin URL contents

- Handle update events on disabled forge worlds properly

- Reduce output from /dmap listareas command to be more useful

- Add /dmap worldgetlimits/worldaddlimit/worldremovelimit commands to allow control of visibility and hidden limits from command line

This release is safe to use on earlier Spigot versions, but has almost no changes relevant to pre-1.16.1 versions.

• Support should properly render all new 1.16.1. blocks
• Rendering of wall blocks should handle the new vertical connection added in 1.16.1
• Should handle pristine 1.16.1 worlds, as well as those upgraded from 1.15.2
• Do be sure to use the latest Spigot 1.16.1 - everyone has been moving very fast on this release!

Please be sure to report any issues found with this release (3.1-beta-1-367) or newer after confirming the issue with the latest Spigot (or PaperMC, when that becomes available).

Hot fix release for v3.0:

• Fix for incomplete initialization of map markers, resulting in no visible markers
• Fix for occasional server shutdown stall due to non-daemon thread

Note: this build was a hotfix, so the version internally will display as '3.0-SNAPSHOT-338' - this is fine: it's just that I didn't run a clean build when I went from the tested hotfix to the 'tagged for release' build.

Includes:

• New fluid rendering model: flowing water/lava rendered to match in-game models, 1.13 immersed blocks rendered properly at surface (partially submerged blocks like slabs, stairs, etc)
• Fix for white stained glass in 1.13.x
• Avoid warnings for 1.13.1 blocks in 1.13

Fluid rendering change applies to all versions, not just 1.13.x

Changes since alpha-1:

• Added support for v1.13.1 (v1.13 support is still present, but will be removed next release)
• Fixed missing textures for blue wool blocks
• Fixed redstone wire rendering in v1.13+
• Fixed door models in v1.13+

• Fixed broken cave rendering in v1.13+ (more than one type of air in v1.13...)

Note: this is respin of initial 3.0-alpha-2, as initial release had breaking issue with pre-1.13 Spigot. If you have problems there, be sure the release version shows as 'Dynmap v3.0-alpha-2-88'

Alpha-2 of Dynmap v3.0 for Spigot 1.8.9-1.13.1
