!!TOP!! Download Go 1.21
Abdilbar Curran
Thanks to everyone who contributed to this release by writing code, filing bugs,sharing feedback, and testing the release candidates. Your efforts helpedto ensure that Go 1.21 is as stable as possible.As always, if you notice any problems, please file an issue.
The latest Go release, version 1.21, arrives six months after Go 1.20.Most of its changes are in the implementation of the toolchain, runtime, and libraries.As always, the release maintains the Go 1 promise of compatibility;in fact, Go 1.21 improves upon that promise.We expect almost all Go programs to continue to compile and run as before.
Go 1.21 includes a preview of a language change we are considering for a future version of Go:making for loop variables per-iteration instead of per-loop, to avoid accidental sharing bugs.For details about how to try that language change, see the LoopvarExperiment wiki page.
Go 1.21 now defines that if a goroutine is panicking and recover was called directly by a deferredfunction, the return value of recover is guaranteed not to be nil. To ensure this, calling panicwith a nil interface value (or an untyped nil) causes a run-time panic of type*runtime.PanicNilError.
To improve forwards compatibility, Go 1.21 now reads the go linein a go.work or go.mod file as a strictminimum requirement: go 1.21.0 meansthat the workspace or module cannot be used with Go 1.20 or with Go 1.21rc1.This allows projects that depend on fixes made in later versions of Goto ensure that they are not used with earlier versions.It also gives better error reporting for projects that make use of new Go features:when the problem is that a newer Go version is needed,that problem is reported clearly, instead of attempting to build the codeand printing errors about unresolved imports or syntax errors.
In Go 1.21 the linker (with help from the compiler) is now capable ofdeleting dead (unreferenced) global map variables, if the number ofentries in the variable initializer is sufficiently large, and if theinitializer expressions are side-effect free.
I'm having a problem trying to install plotly. I proceeded to upgrade anaconda using the command line on Debian 9 and I received the error message "distributed 1.21.0 requires msgpack, which is not installed".
The village bell is ringing, warning that the Minecraft 1.21 update is approaching. While the latest Minecraft update is still probably a ways off, the details have started to spill as of this year's Minecraft Live presentation.
Like last year, Mojang says that the reveal for update 1.21 doesn't represent the full feature list and more will be announced throughout development. Until then, let's get into what we know so far about the Minecraft 1.21 update.
There isn't a release date for Minecraft 1.21 just yet, but it's expected to arrive in the middle of 2024. That tracks with recent years. Minecraft 1.20 and 1.19 both launched in June of their respective years.
Mojang says that the Trial Chambers are built with new copper and tuff block sets as well. If you look closely at the video Mojang shared along with the 1.21 announcement, you can spot what appear to be copper trap doors and window-like patterned copper panes. The blocks that look like a new variant of chiseled stone bricks are likely a chiseled Tuff block.
New to Minecraft 1.21 is a new type of structure: the Trial Chamber is a procedurally generated underground structure designed to present new challenges to explorers. Using the new copper and tuff block sets plus the new copper bulb, Trial Chambers will also include the new Trial Spawner block, which is a variant on the usual mob spawner blocks found in other explorable structures like mineshafts or woodland mansions.
Trial Spawner blocks differ from normal spawners in that they spawn a specific number of enemies and then pause spawning for a time after. They'll dispense loot after you've successfully completed the challenge and emit smoke from their tops to let you know they're currently on cooldown. Trial Chambers are also the home to the newest enemy in the Minecraft 1.21 menagerie: the Breeze, who will be on hand to throw you around with their wind projectiles.
The issuer problems briefly mentioned are a separate subject, but also commonly occurring since k8s 1.21. On that side, as of Vault 1.9.0, newly created Kubernetes auth mounts default to disable_iss_validation=true, as Kubernetes also validates the issuer when the TokenReview endpoint is called, so this was duplicate work anyway.
What I understood my multiple issues is, in k8s 1.21.7 API server is handling service account(JWT Tokens) by refreshing it every hour(3607 seconds), but the vault is not able to do the same in a dynamic way(reloading service account tokens) resulting in authorization errors.
I have been running Zwift through wine on Ubuntu 20.04 LTS for the past two years with no problems. I ran Zwift this way as recently as Tuesday 1/11. Today I received the 1.21 update and now whenever I launch the game I get an error message stating I running a version of Windows which is not supported. I double checked my wine configuration and it has been configured to provide Windows 10 compatibility.
Starting in Kubernetes 1.21, kubectl will include additional HTTP headers in the requests to the API server. By knowing what kubectl command triggered a given request, administrators will have useful information to aid in troubleshooting and enforcing best practices.
I don't think it's a regression brought by 8.1.21, I've had this issue with previous versions (couldn't say which accurately though).
This happened in several locations, one instance of the issue I clearly remember was on session.customs, with a property created there manually.
Trying to re-create it would bring it back, as would creating another property.
Two new deprecations in 1.21 are described below, and you should start planning migration from them to prepare for their eventual removal. As a peek into the next release, check out this recent blog regarding removals in Kubernetes 1.22.
There are some deprecations in 1.21 but no EKS features were removed in 1.21 so you should be able to test your workloads and upgrade without disruption. You can learn about how to upgrade your EKS version in EKS documentation.
PgBouncer 1.21.0 has been released. This release adds one of PgBouncer its mostrequested features: Support for named prepared statements!See the docs on max_prepared_statementsfor details on how the feature works, its limitations, and how to tune thevalue of the max_prepared_statements setting.
The NumPy 1.21.2 is a maintenance release that fixes bugs discovered after1.21.1. It also provides 64 bit manylinux Python 3.10.0rc1 wheels fordownstream testing. Note that Python 3.10 is not yet final. It also haspreliminary support for Windows on ARM64, but there is no OpenBLAS for thatplatform and no wheels are available.
The Python versions supported for this release are 3.7-3.9. The 1.21.x seriesis compatible with Python 3.10.0rc1 and Python 3.10 will be officiallysupported after it is released. The previous problems with gcc-11.1 have beenfixed by gcc-11.2, check your version if you are using gcc-11.
What do you think will be added in minecraft version 1.21? Personally, I don't even have any ideas on this, but I would like something interesting, new, globally, something that will surprise everyone, maybe new biomes, mobs, or maybe something related to game mechanics, and what do you think about this?
Go 1.21 is out, and with it comes a whole slew of improvements like better generic type inference (what this article is about); the new builtin functions min, max and clear; and several new packages in the standard library (maps, slices, cmp, log/slog and testing/slogtest). Read the full release notes here.
I got notified this morning when I went into the OC200 that there was a new firmware update for my ER605. I tried to upgrade from 1.20 to 1.21 and it failed. The router came back on version 1.20 so all is well for now.
So I come home after doing a quick errand and again the controller is telling me there is an update 1.21 for the ER605. Being brave...I tried again...This time it was successful. So my router is now up to 1.21 with no issues.
The documentation for version 1.21 is already updated and available here:
=121
(Note - the version of the documentation on the krpano website can be changed by clicking on the version number in the right-top corner and selecting the version)
Technically the 1.21 version is using the same NWJS runtime as version 1.20.11, so when the old version was working, the new one should also work... And in my own tests on multiple Windows systems (7,10,11) there was no problem...
