What's New in N|Solid 3.4.4 - Jan 2019 Release

We're excited to kick off a brand new year with some useful improvements and updates to N|Solid.

N|Solid Runtime v3.4.4

As always, the latest version of N|Solid includes changes that have recently landed in Node.js LTS release lines; in this case, specifically v10.14.2 and v10.14.1. Changes to the N|Solid runtime in 3.4.4 also include some stability improvements related to our recent launch of N|Solid for AWS Lambda. A cleanup to logging for API methods and upgrades to custom error handling round out the list of changes in this version of the N|Solid runtime.

The Node.js v10.14.2 and v10.14.1 releases included several notable updates, including:

  • An upgrade to c-ares v1.15.0
  • Windows-related fixups:
    • Revert changes to installer causing issues on Windows systems
    • A crashing process will now show the names of stack frames if the node.pdb file is available.

The full changelogs for these Node.js releases, along with attributions, can be found here:

LTS Versions

The N|Solid runtime is available for all currently-supported LTS release lines in Node, including v10.x (Dubnium), v8.x (Carbon), and v6.x (Boron).

  • Node.js v10.x (Dubnium): N|Solid v3.4.4 ships with Node.js v10.14.2; this is the active release line and will be supported until April 2021
  • Node.js v8.x (Carbon): N|Solid v3.4.4 Node.js v8.14.0; release line is in maintenance and will be supported until December 2019
  • Node.js v6.x (Boron): N|Solid v3.4.4 ships with Node.js v6.15.1; maintenance for this release is scheduled to end in April 2019.

N|Solid for AWS Lambda

Added support for the new Stockholm Region

Support for AWS’s newly-announced Stockholm region has been added to N|Solid for AWS Lambda. Users can now select ‘EU (Stockholm) Region’ from the list of regions when selecting their layer version ARN in the getting started screen:

Outdated flag for outdated runtime layer

Users are now able to see if the N|Solid runtime layer, powering their Lambda functions, is outdated. Each function will now display an outdated flag if a newer version of the N|Solid runtime layer has been made available.

Histogram responsiveness

The histogram visualization has been adapted to support screen sizes smaller than 1400 px. This now improves the usability of N|Solf for AWS Lambda on screens that are only 1280px wide (i.e. laptop sizes 13" or smaller).

Invocation lists enhanced sortability

Invocation lists are now sortable by Errors, Cold Starts and Profiles.

Cloudwatch log update

The Cloudwatch log update is taking advantage of a start and end filter, which leads to Cloudwatch displaying more finely tuned logs for the requisite timeframe displayed in N|Solid for AWS Lambda.

Overlapping error and cold start indicators in the histogram

If an error and cold start occur within a similar timeframe, the histogram will now stack and display both red and blue indicator-bars inside the requisite invocation bucket.

CPU profiles will include work done during the cold start init phase

An enhancement to N|Solid for AWS Lambda's CPU profiles will soon include work done during the cold start init phase, providing a richer profile data.

Accounts

It is now clearer which organization users have been invited to. A message indicating the user-account said invitation was meant for will now appear on the invitee’s login screen.
