+- New --skip-security-checks option to allow miners to skip checks when it
+saves bandwidth
+- Skip stratum transaction download when there are no transactions
+- API add Best Share to summary
+- API lock access to some summary statistics (and copy them)
+- Update windows build instructions.
+- Enable backup stratum connections for getwork when the primary pool doesn't
+have longpoll aka solo mining.
+- Check for correct absence of opt_fail_only in cnx_needed.
+- Remove unused variable.
+- The specification for stratum has been elaborated to say that a changed diff
+applies only to new work so do not retarget when submitting shares.
+- Suspend stratum connections to backup pools when there is no requirement to
+potentially grab work from them.
+- Rename rename_thr to RenameThread to match cgminer
+- modminer: Adopt symbolic command names from kanoi
 - Make gen_stratum_work more robust by using a dynamically allocated array for

 - Use base_work for comparison just for cleanness in __copy_work
 - Remove all static work structs, using the make and free functions.
 - Add pool no. to stale share detected message.
 - Add info about which pool share became stale while resubmitting.
--b Copy the work on opencl_free_work
-- Add an extra slot in the max backlog for ztex to minimise dupes.
-- Do not use or count the getworks submitted which are simply testing that pools

-- Track all dynamically allocated memory within the work struct by copying work
-structs in a common place, creating freshly allocated heap ram for all arrays
-within the copied struct. Clear all work structs from the same place to ensure
-memory does not leak from arrays within the struct. Convert the gbt coinbase and

 - opencl: Use new dev_error function for REASON_DEV_NOSTART
 - Provide rudimentary support for the balancing failover strategies with stratum
 and GBT by switching pools silently on getwork requests.
 - Convert remaining modminer and bfl uses of usleep to nmsleep.
 - Convert libztex to nmsleep where possible.
 - Convert unreliable usleep calls to nmsleep calls in ztex driver.
-- Support workid for block submission on GBT pools that use it.
-- Provide rudimentary support for literal ipv6 addresses when parsing stratum
-URLs.
-- Work around libcurl cflags not working on hacked up mingw installations on
-windows.
+- Tidy up device error counts
 - Only increase gpu engine speed by a larger step if the temperature is below
 hysteresis instead of increasing it to max speed.
 - Convert pool not responding and pool alive message on backup pools to verbose
 level only since they mean a single failed getwork.
-- Update work block on the longpoll work item before calling restart threads to
-ensure all work but the longpoll work item gets discarded when we call
-discard_stale from restart_threads.
-- Do not attempt to remove the stratum share hash after unsuccessful submission
-since it may already be removed by clear_stratum_shares.
 - Use stratum block change from backup pools as an alternative to longpoll for
 pools that don't support LP.
 - Round some more static string arrays to 4 byte boundaries.
